The 10 Best Hardtail Mountain Bikes For Ripping Trails and High-Performance

Whether you want a lightweight cross-country rocket or a cheap trail ripper, one of these picks will work for you.

A “hardtail” is a mountain bike with front suspension but no rear suspension. This design can be lighter and less expensive than a mountain bike with rear suspension, as well as simpler to maintain. Think of a hardtail as the workhorse of the mountain bike world.

Sometimes hardtails are simply the best tool for the job, depending on the circumstances. For instance, those just learning to mountain bike may prefer the handling of a hardtail. Kids are often better off with a hardtail for several reasons, particularly the reduced weight. Sometimes the terrain where you ride simply doesn’t warrant a full suspension bike. Or, finally, it might be personal preference drives your desire to ride a hardtail.

Whatever the case, hardtails are alive and well, and we take a closer look at a wide range of bikes to suit your needs from the most basic to advanced racing machines.

What to Consider in a Hardtail Mountain Bike

Why you can trust us, how we tested hardtail mountain bikes, our full hardtail mountain bike reviews.

If you are looking for the best high-performance mountain bikes (full suspension and hardtail, electric and analog), check out our Bike Awards coverage. You’ll find 11 exceptional, award-winning bikes rigorously vetted by our editorial team.

If you’re in search of an efficient race machine, a carbon fiber hardtail might be the bike for you. Hardtails also make great adventure bikes for bikepacking off-road and other long-distance riding shenanigans. Build a hardtail with a longer-travel fork and wide tires and you’ll have a fun ripper for romping around your local trails —and you’ll save money and weight compared to many full suspension options.

For decades, hardtails have appealed to riders due to the infinite ways you can build them up and for their simplicity. Here’s what you need to know about hardtail mountain bikes.

You almost always get more bang for your buck with a hardtail. The design allows manufacturers to either reduce the bike’s overall price or include better components than you would find on comparably priced full-suspension rigs.

Hardtail frames lack rear shocks, pivots, linkages, and the associated hardware. Thus, they are generally lighter than comparable full-suspension frames. For riders who climb a lot, the weight saving can make a difference—both physically and mentally. 

Carbon fiber frames have the best strength-to-weight ratio of any material but are typically more expensive than metal-framed bikes. Despite this, there are desirable characteristics in all frame materials.

Wheel Sizes

Hardtails come with many wheel sizes and gearing options. You’ll find wheel sizes of 29- or 27.5-inches, standard tire widths (up to 2.6-inches), plus-size (2.8- to 3-inches), and fat tires (3-inches and wider). Some hardtails will accept different wheel and tire sizes, allowing you to swap out options to suit your riding needs.

Great for Kids and Tweens

The explosive growth of youth cycling programs and NICA (National Interscholastic Cycling Association) racing got a ton of kids onto the trail and needing mountain bikes. With their combination of lightweight, lower cost, and wheel size options, hardtails make ideal bikes for young riders starting out or teens who quickly outgrow bikes.

Maintenance and Durability

Fewer moving parts mean fewer things that could potentially go wrong, and higher-quality parts mean those parts are less likely to need fixing. The simplicity of not having a rear shock and rear suspension system increases the durability of the bike as it requires less maintenance and fewer replacement parts.

Ride Quality

A hardtail can feel more responsive than a dual-suspension bike when pedaling. The lack of rear suspension creates a more efficient-feeling pedaling platform, so acceleration feels more immediate. 

Climbers especially appreciate the extra responsiveness, though you lose some traction (especially under braking) without the rear suspension. Still, for a fast, efficient ride, nothing beats a hardtail.

Find the Right Fork

After the frame, the fork is arguably the most important part of a hardtail's build kit. You’ll find suspension forks with as little as 80mm of travel on some cross-country bikes, while trail or all-mountain hardtails may have forks with 140mm of travel or more. 

Some hardtails still use forks that lack any suspension. These rigid forks are typically the lightest weight and require no maintenance.

Build One Up

Hardtails also make an excellent second, third...or 10th bike to have around—to loan to friends, for when your primary bike is in the shop, or for dabbling into other areas of riding. 

Many brands (particularly small or mid-sized) offer frame-only options that you can build up on your own or with the help of your local shop. Perhaps you have some old parts kicking around and collecting dust. Well, hardtails are a simple and cost-effective way to put those parts to use!

Bicycling has been vetting and reviewing bikes, gear, and accessories for more than 50 years. The bike recommendations here are based on the extensive work of the test team, which includes Deputy Editor Tara Seplavy, Senior Test Editor Matt Phillips, Test Editor Dan Chabonov, and Maintenance Editor Gabe Ortiz. Together, they have more than 60 years of ride-testing experience and insight that they bring to every recommendation they make.

For hardtail mountain bikes, Tara Seplavy oversaw these selections based on the team’s collective testing experience, as well as her own extensive knowledge of the category.

Chris Case has been riding and racing all manner of bikes for over 30 years. His first “real” bikes were mountain bikes; his racing days began on the rooted trails of southern New England. Formerly the managing editor of VeloNews magazine, he now guides gravel cycling and bikepacking tours with his company Alter Exploration . His garage is filled with his family’s precious collection of bikes, neatly organized and maintained for daily riding, racing, and adventures. Follow him on Instagram at @chrisjustincase .

Many of these bikes were tested by Bicycling 's team of gear editors, which mapped out rides featuring most of the trail elements that you’ll likely encounter. Bikes were pushed hard on flow trails, up steep climbs, down pucker-worthy rocky descents, and through rock gardens. Editors rode these bikes on the terrain best suited for each bike, as well as terrain entirely unsuitable, to see how far the limits could be pushed.

The bikes that weren’t ridden by Bicycling ’s editors were carefully chosen based on their value, quality of parts, our experience riding similar models, and how the overall package meets the needs of the intended rider.

We also consulted with hardtail devotees and coaches who work with junior riders to assess the best choices for younger and beginner cyclists.

Specialized Rockhopper Elite 29

The Rockhopper has been a mainstay of Specialized’s product line longer than most mountain bikers have been alive. The brand spent decades perfecting the Rockhopper into the well-rounded mountain bike platform it is today. And that experience—paired with learnings from its World Cup-winning high-end bikes—translates into a refined quality on the trail.

“The Rockhopper Elite climbs efficiently, is quite capable on singletrack, and isn’t too nervous when descending,” said test rider Tara Seplavy, Bicycling ’s deputy editor.

That is to say, it does everything decently—a quality many buyers in this price range want and expect from a mountain bike.

While the Rockhopper’s frame lacks a tapered headtube and thru axle rear end, the bike strikes a modern and lightweight appearance. The frame has routing for a dropper seatpost (if you wish to add one), its cables route internally on the front triangle, and it has rack mounts.

The components on the Rockhopper Elite don’t jump out, but they also don’t let you down. The air-sprung RockShox Judy TK fork does not perform to the level of the higher-end Recon fork model (more flex under braking and harsher riding). But it is easy to set up for different weight riders and has a crown-mounted lockout for pavement sections.

Specialized offers a bevy of Rockhopper models between $650 and $1,400. We consider the Comp ($950), Elite ($1,150), and Expert ($1,300) models most suitable for trail riding. Specialized also has 27.5-inch wheel Rockhopper variants in these models to fit shorter-height riders.

Aventon Ramblas

With its torquey mid-drive motor, name-brand components, and $2,700 price tag, Aventon’s Ramblas hardtail looks to flip the script and change the perception of hardtail e-bikes—and it succeeds.

At the heart of the Ramblas is Aventon’s all-new A100 motor. The mid-drive unit features 250 watts of sustained power/750 watts of peak power and 100 Newton/meters of torque. It is cleanly mounted to the Ramblas’ front triangle, low-slung on the frame but with sufficient clearance for riding over rocks and logs.

“The bike felt comfortable, proportional, and balanced from the first rip around the trailhead,” Seplavy said.

The Ramblas is well-appointed for its price. Overall, the components are well-suited for a trail-use mountain bike—1x12 SRAM Eagle drivetrain, 4-piston SRAM brakes, 35mm stanchion RockShox fork, dropper seatpost, and 2.4-inch-wide tires. They are all underpinnings of a solid mid-range trail bike—and for a $2,700 hardtail e-MTB, these features are unmatched in the market.

“After riding the Ramblas and checking out other hardtail e-MTBs over the past several years, I think Aventon just reset the entire category with this bike,” Seplavy said.

Trek Roscoe 7

There is so much to love about this bike that it’s hard to decide where to start. The 12-speed Shimano Deore drivetrain (with a 30T chainring and 10-51T cassette) provides a massive range, with gearing low enough to ease the pain of climbing steep hills. Its 29-inch wheels (27.5-inch on XS size) carry speed while maintaining maneuverability on technical trails, and the 2.6-inch tubeless-ready tires offer great traction and a plush ride.

The 140mm travel RockShox Recon SL SoloAir fork has plenty of travel for getting rowdy and can be locked out for added efficiency, such as when climbing a paved road. And speaking of rowdy, a dropper post is a very cool addition and adds to the Roscoe's versatility.

Salsa Rangefinder 29 Deore

The Salsa Rangefinder is one of the least expensive bikes in this test and one of the heaviest. Neither significantly takes away from its abilities on the trail.

“I was pleasantly surprised by the Rangefinder’s performance in most situations,” Seplavy said.

The Rangefinder’s extra heft comes from its oversized aluminum frame, heavy 120mm SR Suntour XCM fork, extra-wide range cassette, and 29x2.6-inch Maxxis tires. These parts, though, also make the Salsa more confident and capable on the trail than the bike’s weight might suggest.

On dirt, the Rangefinder lumbers along. It’s also not light or race-oriented. As Seplavy put it: “The Salsa is not a ‘go fast and take chances’ style bike.”

The Rangefinder's slightly upright positioning, steep seat angle, and low gearing allow you to sit and spin up climbs, despite the bike’s weight.

The Rangefinder is capable, though not fully confident when descending. The wide Maxxis Rekon tires and thru axle fork provide extra grip over roots and precision when picking a line through rocky sections of trail. But the Tektro Gemini brakes with 160mm rotors are insufficient at higher speeds or when the gradient pitches steeply downward. The fork’s lack of damping adjustment also made the fork ping-pong off of rocks when they came in quick succession.

Salsa provides options for riders seeking a Shimano-equipped Rangefinder or one with plus-sized wheels. It offers three other Rangefinder models between $900 and $1,500. Each model has 27.5+ or 29-inch wheel variants. There are Shimano Deore 10 -, 11 -, and 12-speed drivetrain Rangefinder models.

Eastern Bikes Alpaka 29

The Alpaka boasts features that try to emulate a high-end experience at an entry-level price. The aluminum frame is paired with a 100mm travel spring coil fork with a mechanical lockout feature. Stopping power comes from 160mm hydraulic disc brakes with adjustable reach levers.

The 9-speed X-Gear drivetrain is compatible with Shimano and SRAM aftermarket parts. But the 11-34-tooth cassette matched with a 32-tooth chainring up front will limit your ability to climb the steepest pitches.

While the bike‘s quick release hubs are not as secure or fashionable as thru axle wheels, they get the job done at the price. And though the Kenda 2.2-inch tires provide ample traction, the frame is designed to accommodate up to 2.4-inch rubber if you need more cushion and grip.

The cockpit comprises Eastern-branded contact points along with a Velo saddle and grips, completing the package with a touch of comfort not often seen at this price.

Giant Talon 29 1

The Giant Talon 1 is the biggest sleeper in our testing. The Talon’s frame doesn’t have an aggressive trail bike silhouette. It does not look oversized and burly. The plain black paint and blue logo also help to subdue the Giant. Appearances and first looks are often deceiving.

“Once on the trail, the Talon 1 surprised me with its capabilities. It rides like a bike that should cost a couple of hundred dollars more,” Seplavy said.

The Giant’s good ride feel comes down to its fork. The house-brand 100mm travel SXC-32-2 RL fork features 32mm aluminum stanchions, an alloy steerer, and an air spring. These shave weight off the bike while improving stiffness and steering precision. The fork’s rebound adjustment and air spring help you tune the fork for your weight and local trails—a big plus for a bike at this price.

The Tektro M275 brakes on the Talon 1, however, were underwhelming. They slowed the bike down but lacked modulation and a good feel at the lever. The Deore 10-speed drivetrain shifted smoothly but was over-geared for steeper hills compared to the other bikes tested.

Giant offers three models in the Talon range, with the Talon 1 as the most expensive and best equipped for trail riding. For a more premium Giant hardtail trail bike, check out the Fathom 29 models . Starting at $1,500, the Fathoms have longer travel forks, tubeless tires, and dropper posts.

Liv Lurra 2 27.5

The Lurra 2 is Liv’s latest creation for the value-minded hardtail fan.

Designed for performance-minded trail riders who want to rip singletrack, the Lurra offers dedicated frame geometry for the XS and S frame sizes which boast 27.5-inch wheels. Up front, the 130mm Giant fork and 2.6-inch Maxxis tubeless tires offer grip and comfort for roots, rocks, and ruts, and the Giant Contact 100mm dropper seatpost is a nice touch, allowing you to get low and ride with more control. Equipped with a Shimano Deore drivetrain and Tektro disc brakes, the pair offer dependability rather than flash.

The Lurra is generously adorned with multiple water bottle mounts: a set underneath the top tube allows for secure mounting of a small gear pack to fill with snacks or tools or other small items, while a trio on the downtube and another set underneath the downtube allow for multiple mounting positions of two water bottles.

Zize Yonder

While most brands make bikes rated for riders up to 200 or 250 pounds, Zize exclusively focuses on bikes for heavyweight riders. With its chromoly frame and fork, heavy-duty wheels, and Clark's hydraulic disc brakes, the Yonder accommodates riders up to 550 pounds.

The Yonder also features a 100mm wide bottom bracket shell and 3-inch wide 26-inch WTB tires for added rider stability. The bike has a dependable Shimano Deore 10-speed drivetrain, but the gear range is not low enough for optimal riding up steep hills. Though the Yonder is expensive, consider this bike if you're a heavier rider looking to get into off-road riding.

Specialized Riprock

The Riprock 24 is an excellent bike for kids who want to take their riding skills off-road. Designed to accommodate riders between 3-foot-11 and 4-foot-8, this bike comes with 24-inch wheels, a 1x9-speed MicroShift group, and hydraulic disc brakes.

While many mountain bikes for kids use a suspension fork, the Riprock 24 features an aluminum rigid fork. Most bikes at this price use heavy suspension forks that don't work for lightweight riders, but the Specialized’s rigid fork saves weight and looks great. This makes the Riprock 24 well-equipped for young riders' trail riding adventures. Offered in four colors, this bike is also available with 20-inch wheels for riders between 3-foot-5 and 4-foot-4.

Cervélo ZHT-5 GX

Yes, you’re reading that right: Cervélo makes mountain bikes. Though the brand may be more famous as the bike sponsor of the Tour de France-winning Visma-Lease a Bike race team, Cervélo has created this podium-worthy ride for ripping on the dirt.

Sporting a 907-gram (claimed) carbon frame, 69-degree head angle, and long reach top tubes, the ZHT-5 is made for speed. This SRAM GX Eagle 12-speed equipped model also comes standard with a 100mm travel RockShox Sid SL Select fork, e.thirteen TRS Race tubeless wheels, and a RaceFace cockpit.

Expert Chris Case On When to Go Full Suspension Versus Hardtail And Whether to Choose Aluminum Or Carbon.

Is full suspension better than a hardtail.

It depends on the application and terrain. Of course, there are certain types of riding when a full suspension bike is going to provide a faster, safer, and more enjoyable experience—for example, on rockier, more technical downhills. 

Conversely, some situations and locations are better suited to hardtails, for instance, in places where non-technical trails are abundant. If bikepacking is your thing, hardtails can be easier to load up with gear since the opening of the main triangle is easier to fill with a frame bag. But that’s not to say a full-suspension rig won’t work for bikepacking.

Much of the time it’s either personal preference or budget.

Aluminum or carbon?

There are pros and cons to every frame material. Carbon is typically lighter, can dampen more vibrations, and so forth, but if you’re hard on your equipment or crash often, the chances of causing irreparable damage to a carbon frame are higher than with metal frames.

Aluminum is often heavier, and some will say it offers a stiffer, less comfortable ride. But when you factor in saddle choice, tire size and pressure, and the comfort of other touchpoints, it’s hard to isolate the variable of the frame as the only factor on how a bike feels.

I prefer riding metal bikes (titanium) because we have enough disposable stuff in this world already. And carbon is ultimately disposable. Eventually, there will come a time when it is either outdated or broken, and you can either dispose of it or hang it on your wall. I look forward to the day when I can give my titanium bike to my daughter for her to ride.

What do the pros ride?

It used to be that XC racers wanted the lightest machine possible, which was often the hardtail model. Now, however, though many of them still care about weight, there are incredibly light full-suspension race bikes, and having suspension is helpful on the manufactured and natural courses that pros tend to race on (at World Cups, for example).

Chris Case, former managing editor of VeloNews magazine, has been riding, racing, and adventuring by bike for nearly 30 years. His cycling pursuits have taken him to destinations across the U.S. and Europe, Taiwan, Costa Rica, Israel, and beyond. He has stood on the podium at several cyclocross national championships, and is a silver medalist at master’s cyclocross worlds. Today he guides adventurous gravel cycling and bikepacking tours through his company, Alter Exploration.

As Deputy Editor, Tara Seplavy leads Bicycling’s product test team; after having previously led product development and sourcing for multiple bike brands, run World Championship winning mountain bike teams, wrenched at renowned bicycle shops in Brooklyn, raced everything from criteriums to downhill, and ridden bikes on six different continents (landing herself in hospital emergency rooms in four countries and counting). Based in Easton, Pennsylvania, Tara spends tons of time on the road and trail testing products. A familiar face at cyclocross races, crits, and bike parks in the Mid Atlantic and New England, on weekends she can often be found racing for the New York City-based CRCA/KruisCX team. When not riding a bike, or talking about them, Tara listens to a lot of ska, punk, and emo music, and consumes too much social media.

Which Trek mountain bike is right for you?

• Benjamin Haworth
• October 3, 2017

Get to know your Remedy from your Fuel

We have a look over the 2018 range of Trek mountain bikes to see who suits what in a range featuring the Fuel EX, Remedy, Marlin and Powerfly models.

>>> All our recent Trek mountain bike reviews

Getting to grips with 2018 Trek mountain bikes

If you pop over to Trek’s website and click on ‘mountain bikes’ more than 120 bikes appear in front of you. It’s rather daunting. Choice is good but can be bewildering. So we’ve boiled Trek’s MTB range down to the basics to get you started.

>>> Trek road bikes: which model is right for you?

What type of bike do you want?

We think it’s best to split the whole range into three categories and then go from there: hardtail , full suspension and electric .

What type of riding will you be doing?

Once you’ve chosen one of the three categories you can refine it to the type of riding you want to do: cross-country, trail or downhill.

With those two category types chosen you’ll be left with a much smaller pool of Trek models to consider.

We’re going to assume that you already know the type of mountain bike you want. We’re not going to go into any debates or theorising (hardtail vs full suspension, 27.5 vs 29 , Plus vs Fat etc etc).

Trek hardtails

There are five hardtail models in Trek’s range: Marlin, X-Caliber, Roscoe, Procaliber and Stache.

Trek use their own proprietary frame materials. Their aluminium stuff is called Alpha. Their carbon stuff is called OCLV.

Some of their high end hardtails have the ‘IsoSpeed Decoupler’ configuration where the seat tube is designed to flex for compliance.

The Trek Marlin is an entry level cross-country focussed hardtail ranging from £370 up to £550. Thee are four models in total (the Marlin 4, 5, 6 and 7). The frame is Trek’s ‘Silver Alpha’ aluminium.

The Trek X-Caliber cross-country range starts from £650 and tops out at £1,150. The frame is Trek’s ‘Gold Alpha’ aluminium. The frames have internal routing for stealth dropper seatposts. The components are of a higher quality than the Marlins.

The Trek Roscoe range of Plus-tyred trail hardtails running from £800 to £ 1,250. The frame has internal routing for dropper posts and is made from Trek’s ‘Alpha Gold’ aluminium.

The £1,300 to £6,500(!) Trek Procaliber cross-country race bike range can look a a bit confusing; there are aluminium Procalibers, OCLV carbon Procalibers and Super Light OCLV Procalibers. Although the frame material varies the intent of Procalibers is the same: xc racing. The geometry remains the same. All Procalibers have the ‘IsoSpeed Decoupler’ feature of deliberate flex.

The Trek Stache bikes are rather unique in that they are 29er Plus bikes. They roll on some seriously large rubber! Monster trucking hardtails. Price: £1,300 to £3,500.

Trek full suspension bikes

There are five Trek full susser types: Fuel EX, Remedy, Top Fuel, Slash and Session.

All Trek full sus bikes use a version of the ‘ABP’ suspension design. ABP stands for Active Braking Pivot. The rear wheel axle is also the rear pivot. The idea is to prevent the suspension from locking up during rear braking.

Fuel EX, Remedy and Top Fuel bikes also have RE:aktiv rear shock damping. This damping design claims to ‘know’ which forces are coming from the pedals/rider and which forces are coming from the trail, and it reacts accordingly.

The Trek Fuel EX 130mm travel, full sus, all-rounder, trail bikes come as either 29er or as 27.5 Plus. They can be run with either wheel size but are initially purchased with one or the other. Starting from £1,800 for aluminium versions they top out at £6,500 for the top end carbon version.

>>> Trek Fuel EX Plus 9.8 27.5 (2017) review

The Trek Remedy is the 150mm travel trail-cum-enduro bike. Prices range from £2,300 to £6,000. There are aluminium Remedy models and carbon fibre Remedy models. For 2018 they are all 27.5in wheel.

The Trek Top Fuel bikes are full suspension XC race machines. 100mm of travel at either end. Begins with the aluminium Top Fuel 8 for £2,400 and goes up to the £7,800 carbon Top Fuel 9.9 RSL.

>>> Trek Top Fuel 9 (2017) review

2018 Trek Slash

The 160mm travel enduro racing Trek Slash range is all 29in wheels and carbon only for 2018. It’s a bold move by Trek but one that makes the Slash arguably the most defined model in their range.

>>> Trek Slash 9.9 29 RSL (2017) review

The Trek Session is the downhill bike. Aluminium or carbon. And now available as a frameset as a 29er with 190mm of travel. Complete build Sessions are all 27.5in wheel and deliver 210mm of rear travel.

Trek electric mountain bikes

There are three electric mountain bike types: Powerfly, Powerfly FS and Powerfly LT Plus.

The Trek Powerfly hardtails start at £2,300 and go up to £3,300. Aluminium frames with 100mm travel forks up front. The motors come from Bosch. There is also a £4,200 Powerfly Plus with 2.8in tyres.

On the Trek Powerfly FS bikes the ‘FS’ stands for Full Suspension, 130mm of suspension to be precise. The Powerfly FS bikes are aimed at cross-country riding with a bit of rougher stuff every now and then. All but the entry level £3,500 Powerfly 5 FS come with Plus tyres.

Trek Powerfly Launch in Verbier, Switzerland

The Trek Powerfly LT Plus models have more travel (150mm) and fatter tyres (2.8in Plus tyres). These e-bikes are up for a bit more aggro riding and technical trails. Prices: £4,200 to £5,250.

>> Trek Powerfly 9 LT (2018) first ride

Trek Women’s mountain bikes

Even as stalwarts of the whole Women’s Specific Design thang, Trek (along with most other bike brands) are now seemingly moving away from design theories that assume that women’s body proportions are different to men’s.

Bikes fit humans, not genders. Rider height is the only thing you should really be factoring in when choosing a bike. It really is only saddles that need to be a bit different to men’s.

It’s fine to opt for a supposedly ‘men’s’ Trek model if it fits your height. Get the saddle swapped out for a ladies saddle at time of purchase. Sorted.

Having said that, if you want a Women’s bike because you prefer the different colourway and decals, fair enough.

• Trek Skye – entry level cross-country hardtails
• Trek X-Caliber Women’s –  lighter and fancier cross-country hardtails
• Trek Roscoe Women’s – Plus tyred trail hardtail
• Trek Procaliber Women’s – XC racing hardtail
• Trek Fuel EX Women’s – 130mm travel full suspension all-rounder
• Trek Remedy Women’s – 150mm trail/enduro full susser
• Trek Powerfly Women’s – entry level e-bike hardtail
• Top Fuel Women’s – XC racing 100mm travel full suspension

Race Shop Limited models

You may spot some Trek mountain bikes with ‘Race Shop Limited’ (or ‘RSL’) in their model name. These are essentially super high spec models. Often limited edition. And sometimes with slightly tweaked designs (a bit more travel, slacker geometry etc etc).

Mark Webber’s Top Fuel Project One

Trek’s Project One

This is Trek’s custom paint and decals option. Yep, if you have the funds and are prepared to wait a bit for your bike, then you can get a Trek in pretty much any colour scheme you want.

Be warned: you can waste hours (days!) tinklering away with the online Project One dream bike builder.

It’s only available on a few mountain bike models: Top Fuel, Fuel EX and Procaliber.

Trek XC bikes

Trek procaliber.

Wheel Size: 29” Suspension travel: 100mm front

The Procaliber is Trek’s carbon XC hardtail and its lightest mountain bike. It’s a pure cross-country race bike optimized for fast courses where maximum pedaling efficiency is essential for climbing and acceleration. It features a rear IsoSpeed decoupler that provides extra compliance over rough roots and rocks.

Who it’s for: XC riders who want the lightest, most efficient bike, or who ride less-technical terrain.

Trek X-Caliber

Wheel Size: 29” (27.5” for S) Suspension travel: 100mm front

The X-Caliber is Trek’s entry-level, aluminum XC hardtail. The lightweight aluminum frame provides lots of performance on fast courses without breaking the bank. It’s a great option for newer riders looking to get into XC racing.

Who it’s for: XC riders and racers looking for a budget hardtail.

Trek Supercaliber

Wheel Size: 29” Suspension travel: 100mm front / 60mm rear

The Supercaliber is Trek’s lightest, most efficient, full-suspension XC bike. During development, Trek kept the Supercaliber under wraps (they literally hid the rear suspension during races) while Trek’s factory race team tested it at World Cups. The Supercaliber uses a unique IsoStrut suspension system with a frame-integrated shock. This provides 60mm of suspension travel, just enough to take the edge off bumps and harsh impacts while keeping the weight, stiffness, and efficiency close to the Procaliber hardtail. The Supercaliber is designed to be the perfect compromise between a hardtail and a 100mm full-suspension bike.

Who it’s for: XC riders looking for the lightest, most efficient full-suspension race bike available.

Trek Top Fuel

Wheel Size: 29” Suspension travel: 120mm front / 115mm rear

The Top Fuel is Trek’s full-suspension marathon XC bike. The previous generation Top Fuel was a pure XC race bike with 100mm of travel front and rear. In 2020, the travel was been increased to make it more capable on descents. The Top Fuel could be considered Trek’s “downcountry” bike, a cross-country bike that balances downhill performance and pedaling efficiency. It will hold its own in fast XC races, but it’s versatile enough for trail riders who enjoy big rides on technical terrain.

Who it’s for: Marathon XC racers and riders looking for a “downcountry” bike.

Trek trail bikes

Trek Fuel EX

Wheel Size: 29” (27.5” available for XS and S) Suspension travel: 140mm front / 130mm rear

The Fuel EX is Trek’s most popular mountain bike model, and for good reason. The latest generation of this all-rounder has been refined with more suspension travel and modern geometry to make it equally capable uphill and downhill. It’s designed to suit the majority of riders and the widest range of terrain. If you’re looking for a quiver killer bike that will feel comfortable, capable, and efficient enough for all types of riding, the Fuel EX is a top choice.

Who it’s for: Trail riders looking for one bike to handle everything from XC to technical downhill trails.

Trek Roscoe

Wheel Size: 27.5” plus Suspension travel: 120mm front (100mm on XS)

The Roscoe is Trek’s basic aluminum trail hardtail with 27.5” plus tires for traction and comfort. The robust aluminum frame and affordable component builds make it a great choice for newer riders building their confidence and skills on the trail.

Who it’s for: Trail riders looking for a fun, inexpensive, easy to maintain hardtail trail bike.

Trek Stache and Full Stache

Wheel Size: 29” plus Suspension travel: 120mm front / 130mm front and rear

Discontinued in 2021, the Stache and Full Stache were Trek’s 29-plus hardtail and full-suspension models, respectively. These extra-large wheels and tires enhance rollover, traction, and comfort. These models are loved by bikepackers who need to carry large amounts of gear and desire extra comfort for backcountry riding and multi-day journeys.

Who it’s for: Trail riders and bikepackers looking for a mountain bike that maximizes traction and comfort.

Trek Farley

Wheel Size: 27.5” Fat Suspension travel: 100mm front or Rigid

The Farley is Trek’s fat bike specializing in terrain like snow and sand which require the additional “float” and traction of 4-5” wide fat tires. The newest generation of Farley uses 27.5” diameter fat tires instead of traditional 26” fat tires. Trek is a believer that using a larger diameter tire offers better performance in all conditions.

Who it’s for: Riders riding snow and sand.

Trek enduro bikes

Trek Remedy

Wheel Size: 27.5” Suspension travel: 160mm front / 150mm rear

The Remedy is Trek’s playful 27.5” trail bike. Older Remedy models were available with 29” wheels, but with the latest generation, Trek has committed to making the Remedy its sole 27.5” full-suspension bike. An ample amount of suspension travel allows the Remedy to tackle tough and steep downhill terrain while smaller 27.5” wheels make it feel easier to maneuver and throw around. It will suit riders who jump and jib their way down trails and who prioritize style and fun over all-out speed.

Who it’s for: Trail riders looking for a capable and playful bike.

Wheel Size: 29” Suspension travel: 170mm front / 160mm rear

The Slash is Trek’s 29er enduro race bike. It provides the most suspension travel and slackest geometry short of Trek’s Session downhill bike. Available only with 29” wheels, it smooths out the gnarliest terrain and maximizes downhill speed. The Slash is used by Trek’s factory Enduro World Series race team and will suit riders looking for a competitive enduro race bike, or a bike that will enhance their confidence on steep and technical downhill trails.

Who it’s for: Enduro racers and riders looking for the most downhill capable bike that can still be pedaled uphill.

Trek MTB range

Trek has a huge selection of mountain bike models, and within every model, there is a wide range of builds to choose from. The hierarchy within models is described using letters and numbers that can be confusing to uninitiated buyers. Below is a guide to decoding Trek’s naming and numbering system.

[newsletter]

Trek mountain bike range

Trek mountain bike models use a number (e.g. Trek Fuel EX 9.9) to indicate the frame material and component build. Models with a 5 through 8 use aluminum frames, with 5 indicating entry-level builds and 8 indicating top-of-the-line aluminum builds.

Models with a 9 use carbon frames. To differentiate build levels within carbon models, Trek uses a decimal system that ranges from 9.5 to 9.9, with 9.5 indicating entry-level builds and 9.9 indicating top-of-the-line builds.

Higher numbered bikes cost more but are equipped with better components.

For example, a Fuel EX 9.9 ($9,499) has a top-of-the-line OCLV carbon frame, SRAM XX1 Eagle AXS drivetrain, Fox Factory suspension, and carbon wheels, stem, and handlebars. A Fuel EX 5 ($2,399) has a more budget-friendly aluminum frame, Shimano Deore drivetrain, entry-level RockShox and X-Fusion suspension, and alloy wheels, stem, and handlebars. In between are several Fuel EX models that offer different frame materials and component builds so riders can pick the bike that fits their needs and budget.

Trek suspension technology

Trek has a long history of innovation, and it has introduced several ground-breaking technologies to the sport. Here is a list of technology and features that are only found on Trek mountain bikes.

Trek RE:aktiv and Thru Shaft shocks

In 2014, Trek worked with Penske Racing to develop RE:aktiv valve technology for its rear shocks. In RE:aktiv shocks, a spring-loaded valve inside the shock body provides increased low-speed compression for more pedaling support. When the shock's shaft speed increases on rough terrain, the valve opens up to quickly absorb impacts before closing again. RE:aktiv shocks are designed to reduce the need for lockouts and compression adjustment on full-suspension mountain bikes when pedaling on smooth terrain or climbing.

In 2018, Trek added Thru Shaft to its RE:aktiv shocks. Most mountain bike shocks are designed around an internal floating piston, or IFP. When a shock absorbs a bump, a damper shaft moves through the shock and displaces oil. This displaced oil needs to go somewhere, so it pushes against the IFP, compressing a gas charge behind the IFP.

The Thru Shaft design eliminates the need for an IFP by allowing the damper shaft to exit out the bottom of the shock. The damper no longer needs to compress an IFP to create space for displaced oil. This makes the shock more responsive and reduces friction. RE:aktiv Thru Shaft shocks are currently found on the Fuel EX, Remedy, and Slash.

Trek IsoStrut

IsoStrut is a minimal, frame-integrated shock designed to provide the comfort and control of rear suspension while maintaining weight, stiffness, and efficiency that rivals a hardtail. To save weight, instead of an ABP suspension pivot, there is flex built into the seat stays to provide a virtual pivot. In its current form, it is only found on the Supercaliber cross-country bike where it provides 60mm of suspension travel.

Trek Knock Block and Straight Shot down tubes

Most mountain bike frames have a curve in the down tube where it joins the head tube to prevent interference with the fork crown. Trek’s Straight Shot down tubes, however, are straight from the head tube to the bottom bracket to increase frame stiffness and strength. This means the fork crown might hit the down tube if it spins around during a crash.

The Knock Block system prevents this with a chip in the top tube that interacts with a keyed stem, spacers, and headset top cover. The Knock Block stops the handlebars and fork from spinning, preventing the fork crown from striking the down tube. There's also a molded guard on the down tube as a redundant measure. As an added bonus, Knock Block also prevents brake and shift levers from scratching or damaging the top tube.

Knock Block can be found on all of Trek’s carbon mountain bike models and the aluminum versions of the Fuel EX, Remedy, and Slash.

Hopefully this guide to Trek mountain bikes puts you in a better place to select the best Trek MTB to suit you riding needs (and also the best build for your price range).

Understanding Trek's naming system

Trek's naming system follows a similar style to how Canyon names its bikes. Each bike's name is suffixed with a number, with higher value numbers corresponding to pricier and better-kitted bikes. Once we get to 9, Trek adds decimals to the suffix to denote changes in the bike's suspension package. All bikes with a 9 in the name get carbon frames but a 9.7 might get its suspension from Fox's Rhythm range for example, while a 9.8 will get better something from higher in the range. Also, you'll see that a lot of kit on the bikes come from Bontrager, for the uninitiated that's Trek's in-house component brand.

At the '9' level, we also see XT, XO1, and GX finding their way into the names. Yep, you've guessed it, that's the drivetrain the bike comes kitted with.

Another thing that's definitely worth mentioning is that a small selection of Trek's bike range is available through what the brand calls Project One. Project One offers the opportunity to have your bike personalised and custom painted with special, exclusive colours. This will mean you have to part ways with a heap of cash but in return, you'll get a bike that's unique to you.

As with the brand's range of bikes, the price range is vast with bikes starting from £440, right up to £9,200 and that's not even considering the Project One options. There's also a comprehensive range of gravel bikes and e-bikes.

Let's kick things off with the Slash. It's Trek's enduro bike which rolls on 29" wheels and gets 160mm of travel at the rear, paired with 170mm at the front. For 2021 it gets both an aluminium and carbon frame option all of which benefit from Trek's proprietary Knock Block system which saves your top and down tube if your front end spins during a crash. This bike also gets the Mino Link which is a geometry adjusting flip-chip, down tube guards threaded bottom brackets, an Active Braking Pivot, and storage in the downtube. As for the geometry, in the low setting, the Slash sees a 75.6° effective seat tube angle, a 64.1° head tube angle, and a 435mm chainstay. A large frame gets a 486mm reach. If you're after something a little more special, the Slash is available through Project One.

Slash 9.9 XTR

Topping the Slash range is the Slash 9.9 XTR. It gets Trek's OCLV carbon frame with the all-new RockShox Super Deluxe Ultimate shock with an updated ThruShaft damper. At the front, you'll find the RockShox ZEB Ultimate RC2 which features chunky 38mm stanchions. As its name suggests there's a full Shimano XTR 12-speed drivetrain with an e*thirteen LG1 Race Carbon crank. The brakes here also come from the XTR lineup and they come with 4-pot calipers for extra stopping power. This bike rolls on a pair of Bontrager Line Pro 30 which are wrapped with a Bontrager SE5 Team Issue 2.6" Tubeless Ready, Core Strength sidewall, aramid bead tyre at the front and an SE5 Team Issue with the same spec in 2.4" at the rear. It also gets a Bontrager Line Elite Dropper with Bontrager supplying the 820mm wide carbon bar, 35mm stem along with the rest of the build kit.

Slash 9.9 XO1

The Slash 9.9 XO1 gets all of the same trimmings as the 9.9 XTR but benefits from a SRAM XO1 Eagle drivetrain and SRAM Code RSC Brakes, along with a slightly friendlier price tag.

Slash 9.8 GX

Shaving a few thousand pounds of the range-topper is the 9.8 GX. This one is still built around Trek's carbon frame but this one gets a slightly downgraded RockShox ZEB Select+ RC with a RockShox Super Deluxe Ultimate. Here we get a SRAM GX drivetrain with a matching crankset and SRAM Code R brakes. As for the rest of the bike, it's the same as the 9.9 XTR.

Slash 9.8 XT

As its name suggests, the Slash 9.8 XT gets a very similar built kit to the 9.8 GX. However, this bike sees a Shimano XT drivetrain with SLX M7120 four-piston brakes.

Dropping a full £1.8k off of the 9.8 models, the Slash 9.7 is still built around a carbon frame and it swaps the RockShox suspension with a Fox Rhythm 36 fork and a Fox Performance DPX2 EVOL shock. The drivetrain is a mix of SRAM GX and NX Eagle and the wheels here are the alloy Bontrager Line Comp 30's. Those come shod with a Bontrager XR5 Team Issue, Tubeless Ready, Inner Strength sidewall, aramid bead 2.6" tyre at the front with a Bontrager XR4 with the same spec and a 2.4" width at the rear. Trek has also swapped the dropper post for a TransX post and there's Bontrager's own alloy finishing kit.

With the Slash 8, we no longer get a carbon frame but we do get a RockShox Lyric Select+ RC fork with a RockShox Super Deluxe Ultimate at the rear. This bike is driven by a SRAM GX Eagle drivetrain and there's a pair of SRAM Code R brakes. Everything else is the same as what you would get on the 9.7 model.

The Slash 7 rounds of the range with its alloy frame, RockShox Yari RC fork, RockShox Deluxe Select+ shock, and SRAM NX drivetrain. Here we get a pair of SRAM Guide T brakes and the rest of the bike follows suit with the 8.

Trek Remedy

The Remedy is Trek's long-legged trail bike which comes with four models for 2021. It rolls on 650b wheels and gets 160mm of travel at the front, with 150mm at the rear. Much like the Slash, the Remedy benefits from the Knock Block, the Active Braking Pivot, and the Mino Link. Geometry-wise, it gets a 65.6° head angle, a 74.2° effective seat tube angle, and 435mm chainstays in the low position. A large frame gets a 455mm reach, again in that low setting.

The Remedy 9.8 is the only bike in the 2021 line up that gets a carbon frame. It also gets a burly Fox Performance 38 paired with a Fox Performance Float DPX2 EVOL shock at the rear. This bike benefits from a SRAM GX Eagle drivetrain matched with SRAM Code R brakes. As for the wheels, they're a pair of carbon Bontrager Line Elite 30's and they're wrapped with a Bontrager SE5 Team Issue, Tubeless Ready, Core Strength sidewalls with an aramid bead in 2.6" with a Bontrager SE4 Team Issue with the same specs in the 2.4" width. Bontrager also supplies the dropper post with the Line Elite and the 820mm handlebar along with the 35mm stem.

As suggested by the lack of a '9' in its name, the Slash 8 comes kitted with an alloy frame. As for the fork, it's a RockShox Lyrik Select+ RC and that's paired with a RockShox Super Deluxe Select+ shock. This bike is also driven by a SRAM GX Eagle drivetrain and it gets the same brakes as the 9.8 rig. Differing from the range-topper, this build sees in a pair of Bontrager Line Comp 30 alloy wheels which get an XR5 Team Issue tyre that's tubeless-ready with Inner Strength sidewalls and an aramid bead in 2.6", also from Bontrager. At the rear, there's an XR4 with the very same specification. The rest of the bike follows suit with the 9.8 model.

Remedy 8 XT

Rather unsurprisingly, the Remedy 8 XT comes with a very similar build to the 8 but gets an XT drivetrain and Deore M6120 four-pot brakes. Everything else on this build matches the Remedy 8.

The Remedy 7 is the cheapest 2021 Remedy on offer. It gets a RockShox Gold RL fork and a RockShox Deluxe Select+ shock. There's a SRAM NX drivetrain with SRAM Guide T brakes. Apart from that, everything else is the same as what you'll get on the Remedy 8's.

Trek Fuel EX

The Fuel EX is Trek's do it all trail bike. It gets 130mm of rear travel and 140mm at the front. Just like the Slash, the Fuel EX gets built-in downtube storage and the Active Braking Pivot. It comes with a RE:aktiv shock with Thru Shaft, something that you'll only find on Trek bikes. It promises more grip and control with a shock the reacts to the ground faster than anything else on the market, says Trek. This bike also gets the Mino Link, Knock Block, and Straight Shot downtube. The Fuel EX comes in five sizes with XS getting 650b hoops and M upwards getting 29" wheels. However, size S comes with a choice of either wheel size. As for the geometry in the low setting, the bike gets a 66° head angle, a 75° effective seat tube angle, and a 437mm chain stay. A large frame benefits from a 470mm reach.

Fuel EX 9.9 AXS

Topping the range with a pretty hefty pricetag is the 9.9 AXS. On this model, you'll get a Fox Factory 36 with a GRIP 2 damper, paired with a Fox Factory Float EVOL RE:aktiv shock. Of course, we then get wireless shifting from SRAM and the AXS range along with a wireless RockShox Reverb AXS dropper. It rolls on a pair of Bontrager Line 30 carbon wheels and they're wrapped with two Bontrager XR4 Team Issue tyres with Inner Strength sidewalls and aramid beads, measuring in with a 2.6" width at the front and a 2.4" at the rear. Bontrager supplies the finishing kit with a Knock Block stem and a 780mm OCLV carbon handlebar.

Fuel EX 9.9 XTR & XO1

Next up, the Fuel EX 9.9 XTR gets all of the bling. It's built around Trek's OCLV carbon frame and gets a Fox Factory 36 fork with a GRIP2 damper. At the back, there's a Fox Factory Float EVOL, RE:aktiv. As its name hints, this bike comes with a Shimano XTR 12-speed drivetrain with matching XTR M9120 four-piston brakes. There's also an option with a SRAM XO1 drivetrain with SRAM G2 RSC brakes. This one rolls on a pair of Bontrager Line Pro 30 OCLV carbon wheels which are wrapped in a pair of Bontrager XR4 Team Issue, Tubeless Ready tyres with the brand's Inner Strength sidewalls and aramid bead. At the front, there's a 2.6" tyre with a 2.4" at the rear on both wheel sizes. Then the bike comes kitted with a Bontrager Line Elite Dropper and the rest of the kit comes from the same brand.

Fuel EX 9.8 XT & GX

Offering a saving of over £2,000 over the top of the range bike is the 9.8 GX and XT. This bike comes with the same carbon frame as the most expensive bike but sees a downgrade in suspension and drivetrain. Here we get a Fox Performance 36 with a GRIP damper and a Fox Performance Float EVOL, RE:aktiv shock. This rig comes with a choice of drivetrain with either SRAM's GX groupset or Shimano's XT. The GX build comes with SRAM G2 RS brakes whereas the XT model is stopped with a pair of Shimano SLX M7120 four-piston brakes. Everything else on these builds is the same as what you'll find on the 9.9 XTR model.

Fuel EX 9.7

The 9.7 is Trek's most affordable carbon-framed Fuel EX. It comes kitted with a Fox Rhythm 36 with a GRIP damper and a Fox Performance Float EVOL shock. The drivetrain here is a mix of SRAM NX and GX with the former making up the shifter and the latter handing the mech. Gone are the carbon wheels, unfortunately, but instead we get a set of Bontrager Line Comp 30 wheels wrapped in the very same tyres like the rest of the range. The rest of the bike follows suit with the pricier models but there's an alloy bar and stem.

Fuel EX 8 XT & GX

At the sub £3k mark Trek does away with the carbon frames and replaces them with cheaper alloy alternatives. On the priciest alloy option, we get a Fox Rythm 34 Float with a GRIP damper and a Fox Performance Float EVOL RE:aktiv shock. On this build, there's a choice of either a SRAM GX Eagle drivetrain or a Shimano XT with the former benefitting from SRAM G2 R brakes and the latter receiving a pair of Shimano MT4100 levers mated to MT420 four-piston callipers. This bike gets a pair of Bontrager Line Comp 30 alloy wheels and the rest of the build is the same as what you'll get on the 9.7 bike.

Fuel EX 7 NX

On the Fuel EX 7 NX we find a RockShox 35 Gold RL fork and a Fox Performance Float EVOL shock, note that this shock doesn't come with that special RE:aktiv tech. You've guessed it, this one comes equipped with a SRAM NX Eagle drivetrain it gets its brakes from Shimano with a pair of MT4100 levers and MT410 callipers. The rest of the bike, including the wheels and tyres on this bike, is the same as the rest of the alloy range but we see a TransX dropper on this model.

Fuel EX 5 Deore

Rounding off the fairly extensive range is the reasonably priced Fuel EX Deore. It gets a RockShox Recon Silver fork with an X-Fusion Pro 2 shock. Then there's the Shimano Deore 12-speed drivetrain with Shimano brakes made up of MT201 levers and MT200 callipers. The wheels see a downgrade from the rest of the range with an Alex MD35 rim laced to Bontrager hubs. They're wrapped in a pair of Bontrager XR4 tyres and there's a TransX dropper post. The rest of the finishing kit comes from Bontrager.

Trek Top Fuel

Like it or not, but down-country bikes are becoming more and more prolific. Luckily for those who are on board with the trend Trek has a bike for you. It comes kitted with 120mm travel up front and 115mm at the rear with 29" wheels. In keeping with the rest of Trek's bikes so far the Top Fuel also gets a Straight Shot downtube and Trek's Active Braking Pivot. It's also kitted with the Mino Link and Control Freak cable management system. Moving onto the geometry, the Top Fuel sees a 68° head tube angle, a 75.7° effective seat tube angle and a 434mm chainstay. A large frame gets a 470mm reach and those numbers have been taken with the bike in its low setting. As for frame sizes, there's a choice from XS right up to XXL.

Top Fuel 9.9 XX1 AXS

A few hundred pounds shy of the 10k mark, this bike comes with all of the top tech. It's made around a carbon frame with a RockShox SID Ultimate fork with a Race Day Charger damper and a RockShox SID Luxe Ultimate shock. There's a RockShox TwistLoc Full Sprint lockout remote too. As for the drivetrain, here we get a SRAM XX1 Eagle AXS 12-speed wireless set up with SRAM G2 Ultimate brakes. The wheels on this bike area pair of Bontrager Kovee Pro 30 Carbon hoops and they're kitted with a pair of Bontrager XR3 Team Issue, Tubeless Ready tyres with Inner Strength sidewalls and aramid beads in a 2.4" width. Finally, there's a RockShox Reverb AXS wireless dropper post, Bontrager OCLV carbon bar with a 750mm width and 35mm clamp and a Bontrager stem.

Top Fuel 9.9 XTR & XO1

Next up, the Top Fuel XTR and XO1 models get the same carbon frame but this time there's a Fox Factory 34 Step Cast with a FIT4 damper paired with a Fox Factory Float shock. This bike also gets the RockShox Twistloc remote lockout. With this model, there's a choice of either a SRAM XO1 drivetrain or the Shimano XTR set up. The XO1 model gets SRAM G2 RSC four-piston brakes while the XTR gets XTR M9100 brakes. Everything else on the bike is the same as the AXS model but the dropper, which is a Bontrager Line Elite.

Top Fuel 9.8 XT & GX

The Top Fuel 9.8 sees a saving of £2.4k and gets its suspension from RockShox with the SID Select+ RL fork and RockShox SID Ultimate RL shock. There's a choice of drivetrain on this bike too between either a SRAM GX Eagle 12-speed with SRAM G2 RSC brakes or a Shimano XT drivetrain with SLX M7000 brakes. Everything else on this bike is the same as its pricier brethren.

Top Fuel 9.7

The 9.7 model is the cheapest with a carbon frame and it comes with a RockShox Reba RL fork and a Fox Performance Float DPS shock. There's a SRAM NX Eagle 12-speed drivetrain with Shimano brakes consisting of MT501 levers and MT500 calipers. This bike makes a move to Bontrager Kovee Comp 23 alloy wheels and they get the same tyres as the rest of the range. We get an alloy cockpit and a Bontrager Line Dropper.

Top Fuel 8 NX

At this price point, Trek introduces alloy frames into the mix. With the 8 NX there's a RockShox Recon Gold RL Solo Air with a Fox Performance Float DPS. There's still a remote lockout here but it comes from Bontrager in the form of the Drop Lock. As its name suggests, this bike is driven by a SRAM NX drivetrain and it's stopped with a pair of SRAM Level T brakes. The rest of the bike is the same as what you'll find on the 9.7 model.

Top Fuel 7 SX

The Top Fuel 7 SX is the most affordable bike in the range featuring suspension from RockShox with the Judy SL Solo Air fork and the X-Fusion Pro 2 shock. There's a SRAM SX Eagle 12-speed drivetrain with Shimano MT200 brakes. This one rolls on the same alloy wheels as the rest of the range with the same tyres. In fact, apart from the TransX dropper post, everything else matches the Top Fuel 8 NX.

Trek Full Stache

While the Full Stache hasn't had an update for 2021, it seems rude not to include it as there aren't an awful lot of full suspension 29+ bikes on the market. Of course, it rolls on 29" wheels with chunky 3" tyres. It also has 130mm of travel at both ends but the frame is compatible with up to a 140mm fork if you fancy some extra lairy riding. There's also the Mino Link, Control Freak cable management and the Knock Block. It's built around an aluminium frame and gets a 67° head tube angle, a 75.5° effective seat tube and a 430mm chainstay in the low setting. A large gets a 480mm reach, again in the low setting.

Full Stache 8

With its aluminium frame, you'll find a RockShox Pike Select Plus RC fork with a Fox Performance Float EVOL RE:aktiv shock. There's a SRAM GX Eagle 12-speed drivetrain, aTruvativ Descendant 6k crank and SRAM Guide R brakes. This bike gets a pair of SUNringlé Duroc 40 SL wheels and they're shod with a pair of Bontrager XR4 Team Issue, Tubeless Ready tyres with Inner Strength sidewalls and aramid beads. We get a Bontrager Line Dropper on this bike with a 780mm wide alloy bar, also from Bontrager.

Trek Supercaliber

Filling the role of the full suspension cross country bike is the rather unique looking Supercaliber. The standout feature of this bike is its IsoStrut suspension platform. It offers 60mm of fully tunable travel and what makes it special is that it does away with a rocker link thus saving a chunk of weight. The IsoStrut is also a structural feature of the frame which Trek says prevents twisting, flex and deflection which the brand claims offers a more direct power transfer. The whole range of Supercalibers feature carbon frames rolling on 29" hoops, Straight Shot downtube and the Knock Block. The geometry on this bike sees a 69° head angle, 74° seat tube angle and a 430mm chainstay. The reach of a large frame measures in at 455mm. There are six sizes from S to XXL and an ML size which gets a longer top tube than the M. Up front there's 100mm of travel.

Supercaliber 9.9 XX1 AXS

The Supercaliber 9.9 XX1 AXS takes the crown as Trek's most expensive mountain bike. It comes dripping with top-shelf kit such as the RockShox SID SL Ultimate with a Charger Race Day damper and a Fox Factory IsoStrut shock. This bike gets SRAMs XX1 Eagle AXS wireless drivetrain with the carbon crank and SRAM Level Ultimate brakes. It rolls on a pair of Bontrager Kovee XXX OCLV carbon wheels and they're wrapped with a set of 2.2" Bontrager XR2 Team Issue, tubeless ready tyres with Inner Strength Sidewalls and aramid beads. Then the finishing kit also comes from Bontrager and the line of carbon components, including a 720mm wide handlebar.

Supercaliber XX1 & XTR

Next up the Supercaliber 9.9 XX1 and XTR get all of the same kit as the priciest model but they drop the fancy wireless shifting. Instead, there's a choice of either a SRAM XX1 Eagle drivetrain with SRAM Level Ultimate brakes or a Shimano XTR drivetrain with XTR M9100 brakes.

Supercaliber XT & GX

Seeing a considerable saving from the rest of the range, the Supercaliber 9.8 GX and XT models get a downgraded Fox Performance 32 Step-Cast fork with a GRIP2 damper. There's also that IsoStrut suspension also provided by Fox but this model doesn't get that sleek Kashima coating, coming from the brands Performance line-up. These models come with a choice of either a SRAM GX Eagle 12-speed groupset with both choices coming kitted with Shimano Deore XT M8100 brakes. Here we get a pair of Bontrager Kovee Pro 30 carbon wheels, then the rest of the kit is the same as what you would get on the other bikes.

Supercaliber 9.7

The Supercaliber 9.7 is the most budget-friendly option in the range. It's still built around that OCLV carbon frame and the Performance level IsoStrut shock but gets a RockShox Reba RL fork. This one is driven by a SRAM NX Eagle drivetrain and it's stopped by brakes from Shimano with the MT501 levers and MT500 calipers. This model gets slightly narrower Bontrager Kovee Elite 23 carbon wheels with the same XR2 tyres but the rest of the bike comes from Bontrager's alloy line of kit.

Trek Procaliber

The Procaliber is Trek's lightweight cross country hardtail. Compared to the Supercaliber it presents a mighty cash saving if you're looking for a race-ready XC bike. That doesn't mean that it's not without some cool tech, however. The Supercaliber benefits from what Trek calls the IsoSpeed decoupler which allows the set tube to rotate independently from the top tube to seatstay junction which Trek says offers some vertical compliance without sacrificing pedalling efficiency. As with the rest of the range, this bike gets the Straight Shot downtube and Knock Block too. Each bike in the Supercaliber line up comes with a carbon frame which rolls on 29" wheels and can fit up to 2.4" rubber. Here we see a 68.8° head angle, a 73.8° seat tube angle and 432mm a chainstay. A large frame benefits from a 450mm reach and there are six sizes, from S up to XL, including an ML size which gets a longer top tube than the M. The Procaliber gets 100mm of suspension.

Procaliber 9.8

Built around an OCLV carbon frame the Procaliber 9.8 comes with a Fox Performance 32 Step-Cast fork with a GRIP damper. It's driven by a Shimano XT drivetrain with Deore XT M8100 brakes but this one gets an e*thirteen TRS Race Carbon crank. The wheels here are a pair of Bontrager Kovee Elite 30 carbon wheels and there's a pair of Bontrager 2.2" XR2 Team Issue, tubeless-ready tyres with Inner Strength sidewalls and aramid beads. The rest of the kit comes from Bontrager too, with a 720mm wide carbon handlebar.

Procaliber 9.7

This model comes equipped with a RockShox Reba RL Solo Air and a SRAM GX Eagle 12-speed drivetrain with Shimano MT501 brake levers hosed to MT500 calipers. This bike gets Bontrager's Kovee Elite 23 wheels, then the rest of the bike matches the 9.8 model.

Procaliber 9.6

On the 9.6 model of the Procaliber you'll get a RockShox Recon Gold RL and a mixture of Shimano kit making up the drivetrain. There's an SLX M7100 shifter and an XT M8100 derailleur. With this model there's the move over to alloy wheels, they come from Bontrager and the Kovee's. Then there are the same tyres as the rest of the range and an all-alloy finishing kit from Bontrager.

Procaliber 9.5

Finally the Procaliber line-up is rounded off with the 9.5. Even as the cheapest bike, it still gets that OCLV carbon frame but sees a RockShox Judy SL fork. There's a full Shimano Deore 12-speed drivetrain with Shimano MT200 brakes. Then the rest of the bike features the same kit that you'll find on the 9.6 model.

Trek X-Caliber

If you're looking for a race-ready cross country bike but you're on a budget, the X-Caliber is the bike for you. Accommodating for its affordable price point is an aluminium frame rather than the carbon you'll find on its pricier sibling, the Procaliber. The X-Caliber comes kitted with rack mounts, so it's bike-packing ready, along with a mount for a kickstand. All frames feature internal routing and they all come kitted with Trek's Blendr stem. The X-Caliber comes with either 650b wheels on sizes XS and S with all larger bikes (up to XXL) roll on 29" hoops. As for the geometry, there's a 73° effective seat tube angle on sizes M and up while the smaller two sizes get a 73.5° effective seat tube angle. Then there's a 69.5° head tube angle (S and XSs get a 69.3° HA) and a 438mm chainstay on M and up, and a 425mm chainstay on the smaller bikes. Sizes S to XL get 100mm of travel leaving XS with just 80mm. Although, the frame will accept a maximum of a 120mm fork while the XS can accept a 100mm fork.

X-Caliber 9

Heading up the range, the X-Caliber 9 gets a RockShox Judy Silver Solo Air with a TurnKey remote lockout. This bike gets a Shimano SLX M7100 12-speed drivetrain with Shimano brakes made up of an MT401 lever and an MT400 caliper. The wheels on this one are a pair of Bontrager Kovees and they're wrapped with a pair of Bontrager XR3s in the 2.3" width on all sizes. The finishing kit comes from Bontrager too with an alloy bar, stem, and seat post.

X-Caliber 8

The middle of the range X-Caliber 8 comes with a RockShox Judy SL Solo Air fork with a SRAM SX Eagle 12-speed drivetrain. Stopping the bike is a pair of MT200 brakes from Shimano. As for the wheels, the rims come from Bontrager with a pair of kovees and they're laced to Formula DCL-141Q hubs. Then the rest of the bike is the same as the X-Caliber 9.

X-Caliber 7

The X-Caliber 7 gets much of the same kit as the X-Caliber 8 with the only difference in spec being its Shimano Deore 10-speed drivetrain.

Trek Roscoe

If you're looking for a trail orientated hardtail, the Roscoe fits the bill. Each build comes properly sorted with dropper posts, 120mm of travel (size S gets 100mm), 1x drivetrains and alloy frames. The bike also rolls on 650b+ wheels and tyres. They all feature internal cable routing, rack and kickstand mounts too. Onto the geometry, the Roscoe sees a 67.3° head angle, a 70.8° effective seat tube angle (with the medium frame getting a 70.7° effective seat angle and the S and XS getting 71.2° and 71.1° angles respectively), and a large frame gets a 428mm reach. As a 650b+ bike, it can run either 27.5x2.8" or 29x2.4" rubber.

On the Roscoe 8, you'll find a RockShox 35 Gold RL fork with a SRAM NX Eagle 12-speed drivetrain with Shimano brakes in the form of the MT501 lever paired with an MT500 caliper. It's worth noting that the fork comes with a flexy QR axle. The wheels here are made of rims from Bontrager and the Line 40s with a Bontrager hub at the front and a Formula hub at the rear. This bike gets a pair of Maxxis Rekon tubeless tyres with a 2.8" width and then the rest of the kit comes from Bontrager and the alloy range apart from the dropper post, which comes from TranzX with the JD-YSP18.

The Roscoe 7 benefits from most of the same kit as the 8, but this one gets a SRAM SX Eagle 12-speed drivetrain and Shimano MT200 brakes.

On the cheapest Roscoe 6 you'll get an SR Suntour XCM 32 coil sprung fork with a Shimano Deore 10-speed drivetrain and MT200 brakes. This bike then rolls on Alex MD35 rims and Formula DC hubs which get a pair of Kenda Havok, wire beaded, 2.8" tyres. As for the rest of the build, that's just the same as the rest of the range.

Trek Marlin

If a sub £1k cross country, everyday bike is more your speed then it's worth checking out the Trek Marlin. Each bike in the range comes with an alloy frame and a fork with 100mm of travel (XS frames get 80mm). There are also rack and stand mounts, the Blendr stem, and internal cable routing. XS and S sizes roll on 650b wheels while sizes M to XXL get 29" hoops. On the Marlin, you'll get an effective seat tube angle of 73.5° on the XS and S frame while everything else benefits from a 71.9° effective seat tube angle. As for the head angle, on the smaller sizes it'll measure in at 69.3° and from M upwards it's a couple of degrees steeper at 69.5°. All frame sizes share a 438mm chainstay length and a large frame gets a 451mm reach.

The Marlin 7 comes kitted with a RockShox Judy coil sprung fork with a Shimano Deore 10-speed drivetrain and Shimano MT200 disc brakes. The wheels are made of Bontrager Kovee rims laced to Formula DC hubs and they're wrapped with a pair of Bontrager XR2 Comp 2.2" tyres with wire beads. The rest of the bike comes with Bontrager's own finishing kit.

Trek Farley

Perhaps fat bikes are more your things. Allow me to introduce the Farley. There are two in the 2021 range with an alloy and a carbon option which, of course, roll on 4.5" tyres. Both bikes come with a dropper post, horizontal sliding dropouts, ideal for single speed setups and tubeless-ready tyres. As for the geometry, the Farley gets a 69° head angle, a 73° effective seat tube angle and a 455mm chainstay. The reach on a large is 441mm and there are four sizes available, from S to XL. 

The Farley 9.6 gets an OCLV carbon frame with a Bontrager Haru OCLV fork. The drivetrain on this bike comes from SRAM and the GX Eagle 12-speed shifting. As for wheels, they're Sunringle Mulefut 80 SL rims laced to Bontrager alloy hubs. Those are wrapped in a pair of Bontrager Barbegazi Team Issue, tubeless-ready tyres with inner strength sidewalls and aramid beads. The dropper kitted here is a TransX JD-YSP18 and the rest of the kit comes from Bontrager with a 750mm wide bar.

The Farley 5 is Trek's best value fat bike and it's built around an alloy frame. It gets a Shimano Deore M4100 10-speed drivetrain with SRAM Level brakes and there's a Race Face crank. It gets the same wheels as the 9.6 but the tyres here are a pair of Bontrager Gnarwhals. The rest of the kit is the same as the 9.6. It's worth mentioning that while the Farley 5 comes with a rigid fork, it'll happily accommodate a 100mm travel suspension fork.

Trek Session

The Session needs no introduction, but it's the brand's 650b downhill bike. There's only one model in the 2021 range which is built around an alloy frame. It gets Trek's Active Braking Pivot and the geometry adjusting Mino-Link. Up front, there's 200mm of travel and at the rear, there's 210mm. In the low setting, the Session gets a 63.6° head angle, a 445mm chainstay and a large frame gets a 426mm reach. There are four sizes, from S to XL and the 8 27.5 model will set you back £4,200

Trek Ticket

Finally, rounding off the Trek range of mountain bike is the Ticket. It's available as the full suspension, Ticket S (pictured) with 100mm of travel and the Ticket DJ, which is the hardtail version. Both come as a frame only with prices starting from £725, up to £1,400.

Trek Roscoe 6, 7, 8, and 9 Compared: Which One to Choose?

CyclistsHub is supported by its readers. We may receive a commission if you buy products using our links.

In this article, I’ll help you navigate the Trek Roscoe mountain bike family by comparing the Roscoe 6, 7, 8, and 9. 

You’ll learn about the differences between each model, who they are best suited for, and more. 

Plus, I’ll tell you which model gives you the best value for your money to help make your decision easier.

KEY TAKEAWAY

Trek Roscoe mountain bikes are ideal for trail riding thanks to their geometry and long fork travel. They also have dropper posts and 1X drivetrains. On the other hand, they are relatively heavy despite not having a rear suspension.

Trek Roscoe 6 vs. 7 vs. 8 vs. 9

The following table summarizes the main differences between all Roscoes that belong among the Trek hardtail mountain bikes .

Roscoe Pros & Cons Summary

I summarized the pros & cons of the Roscoe series below.

Roscoe Pros

• Trail geometry with long fork travel
• Dropper post
• Modern 1X drivetrain
• Tapered head tube
• Availability in multiple sizes and colors
• Compatible with racks, kickstands, etc.
• Partially internal cable routing
• Lifetime warranty

Roscoe Cons

• Relatively heavy
• No full-suspension
• Only aluminum frame

Roscoe Main Features

Let me now explain the most important features of the Trek Roscoe bikes.

Frame and Geometry

All Roscoe bikes have the same aluminum hardtail trail frame , available in XS-XL sizes and many colors that vary between models.

Unlike Trek Marlin bikes , all sizes have the same shape and no curved top tube.

The frame has a trail geometry . This means a slack head angle and a longer wheelbase for added stability in technical terrain. It can also fit 140-150mm forks, 29-inch wheels, and up to 2.6″ tires.

However, this geometry makes it less suitable for pedaling uphill than Marlin bikes, for example. But don’t worry. It still climbs well.

It’s worth noting that when I was writing this article, the Roscoe 6 had a different frame than the other models. The frame had wider tire clearance and a slightly different shape.

Roscoe mountain bikes have longer suspension travel ranging from 100mm to 140mm, which makes it easier to ride on technical trails.

The Roscoe 6 has a suspension travel of only 120mm, and the XS size has only 100mm travel. The other models have suspension travel of 140mm *. For comparison, Trek X-Calibers and Procalibers have 100mm travel.

*The difference is the type of fork they use, ranging from RockShox to FOX forks.

All Roscoe bikes come with a suspension lockout feature. You can lock the suspension when riding smooth surfaces to reduce energy loss when pedaling.

Wheels and Tires

The wheel size is the same on all Roscoe bikes except for the Roscoe 6, which uses 27.5-inch wheels. The other models use 29-inch wheels , which offer extra stability compared to 27.5-inch wheels.

All Roscoe models except for the Roscoe 6 have the same rims, which are the Bontrager Line Comp 30 rims. These rims are tubeless-ready.

The Roscoe 7-9 models come with Bontrager XR4 Team Issue tubeless tires. These tires have a width of 2.6 inches, which provides enough grip and comfort on rough or loose surfaces.

The groupset is one of the main areas where the different Roscoe models vary, and it’s likely the deciding factor for many people.

The primary difference between them is the number of gears . Fortunately, all Roscoe bikes have a modern 1X drivetrain .

1X drivetrains are popular because they are easy to maintain and shift, and they are also lighter than 2X or 3X groupsets. However, they have fewer gears, which means you may not always find the ideal one for your preferred cadence.

The Roscoe 6 has only 10 gears, while the higher-end models come with 12 gears . The groupsets range from Shimano Deore through SRAM NX Eagle to Shimano XT.

It’s up to you and your preferences to decide which one you choose. As a beginner, you probably won’t notice much difference in shifting speed and reliability.

Another difference between the Roscoe models is their brakes. The Roscoe 6 and 7 use Shimano MT200 hydraulic disc brakes , while the other two models use MT520 and MT6120, respectively.

The MT200 brakes are only 2-piston, while the MT420 and MT6120 are 4-piston, providing better stopping power.

If you like to push your bike to the limits or are a heavier rider, you will appreciate the additional stopping power provided by the 4-piston brakes. This is achieved by larger brake pads and braking area.

All Roscoe bikes come with a dropper post , which is especially useful on trails and descents where the saddle can obstruct you. With the dropper post, you can easily lower it (and subsequently raise it for more comfortable pedaling).

Roscoe bikes also have partially internally routed cables to improve their appearance. They have internal cable guides to prevent rattling inside the frame.

The frame also has a double-sided chainstay guard and a downtube guard for protection on rough terrain.

Roscoe frames also have mounts for kickstands and racks , making it easy to install these accessories.

You can also use a Blendr stem , which is a mechanism that allows you to easily attach Bontrager’s accessories like lights, speedometers, or bike computers.

Lastly, Roscoe bikes come with lock-on grips that are easier to install and replace than slip-on grips.

So, which bike from the Roscoe family is the best?

In my opinion, the Roscoe 8 provides the best value for the money. It features 4-piston disc brakes and an SRAM NX Eagle groupset, which are two significant upgrades compared to the Roscoe 7.

The price difference between the Roscoe 8 and 9 might be difficult to justify for less experienced riders, even though it comes with a better groupset and fork.

On the other hand, I recommend avoiding the Roscoe 6, as it has an older frame with 27.5-inch wheels and shorter fork travel.

Trek Roscoe FAQ

Trek Roscoe mountain bikes are a great option for riders who want to tackle technical trails on a budget. Roscoe bikes are reasonably priced and feature geometry designed for better stability on technical terrain. Plus, they come in various sizes and colors to ensure you find the best fit. It’s also worth noting that Roscoe bikes come with a dropper post, which is a valuable feature on technical trails. However, Roscoe frames are made of aluminum only, which makes them heavier than some other options. Additionally, the components on Roscoe bikes don’t reach high-end status. As a result, performance-oriented mountain bikers may want to consider other series.

Roscoe bikes (7 to 9) differ mainly in components like the groupset, fork, brakes, weight, and price. The Roscoe 6 has a slightly different frame and different components. I recommend reading this entire article for more information and a helpful comparison table.

Roscoe mountain bikes are an excellent choice for riders who want an affordable hardtail trail bike. They are versatile and feature modern trends like a 1X drivetrain and dropper post. Plus, they have mounting options that make adding accessories like racks and kickstands easy. The high-volume tires and long front suspension travel make for a comfortable ride by absorbing large bumps.

Roscoe mountain bikes are relatively heavy, considering their price range. They also don’t come with the highest-end components or a carbon frame. The suspension fork could also be better.

Trek Marlin vs Trek Roscoe, which Trek hardtail is right for you?

Comparing Trek's two latest hardtail mountain bikes

Katherine Moore

Choosing which bike to buy, whether it’s your very first mountain bike, an exciting upgrade or you’re looking to try something different, is always a task worth taking your time over.

While on the face of it, some bikes may seem similar, when you dig down into the bike’s geometry, frame design, suspension setup and specs, there are often key differences that go hand-in-hand with their intended use.

Take two of Trek’s most popular hardtail mountain bikes : the best-selling Marlin and the more aggressive Roscoe. On the face of it, they look very similar, but understanding the differences will help you work out which is best suited to you.

What type of riding are you doing?

Forget drool-worthy paintjobs, detailed geometry figures and component choices to start with – the most important thing to consider when choosing the best mountain bike for your needs is to align the type of bike with the style of riding that you’re likely to be doing.

Mountain biking is a broad church, after all, covering everything from multi-day cross-country stage races to four-minute downhill runs, and everything in between.

Bikes intended for these different mountain biking disciplines are designed accordingly; cross-country bikes are best for pedalling and downhill bikes are best for descending. Those in between, including downcountry bikes , trail bikes and enduro bikes , are typically built to balance pedalling efficiency and trail capability on a sliding scale between them.

The Trek Marlin is a beginner-focused hardtail that sits at the cross-country end of the mountain biking spectrum, with a 100mm short-travel suspension fork.

However, the third-generation Marlin has been updated with a number of features that make it both more trail-friendly and upgradeable.

Cleverly, the Marlin also boasts some additional mounts that make it a versatile choice beyond mountain biking, with the capability to fit a kickstand, pannier rack and bags. This enables it to double up as a rugged tourer or urban commuter for cycling to work .

With a greater level of suspension on offer (140mm on most models), more trail-focused geometry, mountain-bike specific frame features and larger tyres, the Trek Roscoe, on the other hand, is a dedicated trail hardtail built for more rugged terrain.

Both the Marlin and Roscoe are alloy hardtails, which helps to keep the prices towards the budget end of the spectrum. Expect to pay more for a lighter carbon fibre frame if you cast your eye at the Procaliber family, designed with fast-paced cross-country racing in mind.

We’ll take a look at the specific features of the Marlin and Roscoe in turn. Key to weighing up which of these hardtails is best for you is deciding what you want to do with it, whether you’re looking to push yourself on challenging trails or are looking for something that’ll help you get about town just as easily as it takes on a local off-road loop.

Because the frame design is so key to how bikes feel to ride, geometry is a good place to start when comparing bikes. You can read BikeRadar’s full guide to mountain bike geometry for more; we’ll focus on the key numbers when comparing the Trek Marlin and Trek Roscoe here.

In terms of head tube angles, while the Marlin’s geometry, updated on the newest third-generation models, has recently been slackened to 66.5 degrees, the Roscoe hardtail is designed around an even slacker 65-degree angle.

Essentially, the slacker the head tube angle, the further forward the front wheel is placed in front of you, and the more capable the bike becomes over rougher terrain.

In combination with the greater level of suspension travel, the slacker head tube angle of the Roscoe means you have to shift your weight further forwards on the bike to weight the front wheel. This results in a more aggressive riding position compared to the more upright position of the Marlin.

Seat tube angles are similar across the Marlin and Roscoe, at 73.4 and 73.1 degrees respectively, steepened to enhance pedalling efficiency for flatter gradients, pedal ups and linking sections of trail.

Both the Roscoe and Marlin offer a wide range of frame sizes, including Trek’s extra size option sitting between medium and large. However, it’s the Marlin that can accommodate the widest range of riders, catering for teens as well as adults with the XXS option.

Another point of difference between these two hardtails is the handlebar width, with the Marlin using 690/720/750mm bars (dependent on frame size), while the Roscoe is fitted with wider 750/780mm handlebars, again for added control on steeper and trickier off-road descents.

With a cross-country-oriented design for efficient pedalling, the Marlin uses a short-travel 100mm fork.

For a more trail-ready ride, the new third-generation Marlin can accept a 120mm-travel fork on all frame sizes from XS up, if you fancy upgrading your ride as you gain confidence and start to tackle larger trail features.

With a hefty 140mm suspension on offer, the Roscoe is positioned firmly in the aggressive hardtail category, best suited for trail riding.

The budget Roscoe 6 is the only exception, retaining a shorter-travel 120mm fork.

Frame features

With a more moderate level of suspension, the Marlin can double up for urban duties as well as hitting the dirt, so Trek has added a number of frame features with the commuter in mind.

You’ll find a mount for a kickstand as well as pannier rack mounts, so you can kit out your Marlin to carry luggage, whether that’s using it as a commuter bike around town or on a longer bike touring adventure.

The updated, third-generation Marlin frame also boasts internal cable routing for a dropper post, should you wish to add one later down the line. A rubberised chainstay guard comes pre-fitted to all Marlin models, to protect the frame from chain slap and minimise any noise.

As a more dedicated dirt shredder, the Roscoe doesn’t include the same rack and kickstand mounts, streamlining the frame.

Instead, you’ll find an in-built down tube guard in addition to the chainstay protector, designed to take the impact of stones and other trail debris.

You’ll also find ISCG mounts around the bottom bracket on the Roscoe, allowing you to fit a chain guide or bash guard.

Wheels and tyres

While most of the Marlin and Roscoe models on offer use modern 29er wheels , they do vary by frame size to offer the best fit for shorter riders.

For the Marlin, size XXS uses 26in wheels, sizes XS and S both use 27.5in wheels (also known as 650b ), while the larger sizes use 29er wheels.

There are slightly fewer sizes on offer with the Roscoe, starting with XS, which uses 27.5in wheels. With the exception of the Roscoe 6, which is built with 27.5in wheels across all sizes, the rest of the Roscoe models and sizes use 29in wheels.

While we’re talking rolling stock, one of the main differences between the Marlin and Roscoe is the tyre clearance, hence the width of tyres they are fitted with.

The new Marlin can accommodate up to 2.4in-wide mountain bike tyres with 29in wheels, whereas the Roscoe is fitted with plus-size 2.6in rubber, also with 29in wheels, for added traction. This wider rubber is fairly typical of trail hardtails, yielding extra grip in lieu of rear suspension .

To drop or not to drop

A dropper post is a key component when it comes to tackling trail features and steeper off-road terrain. You’ll find a dropper post included on some, but not all Trek hardtail mountain bikes.

A standard seatpost saves on both cost and weight, so with the exception of the top-tier Marlin 8, the Marlin family isn’t specced with a dropper. The good news is that internal cable routing means you can easily add one later though – a popular option when it comes to upgrading a mountain bike .

All Roscoe models are equipped with a dropper post from the get-go, correlating to their design for rowdier off-road pursuits.

With five models on offer, starting from a budget-friendly £475 / €599 for the Marlin 4 up to £1,230 / €1,349 for the Marlin 8, the Trek Marlin makes for an accessible entry to mountain biking. Third-generation Marlin models start from £760 / €849 with the Marlin 6.

The Roscoe starts at £1,160 / €1,299 / $1,199.99 for the Roscoe 6, though bikes from the Roscoe 7 (£1,620 / €1,799 / $1,899) onwards feature the latest frame, with the range topping out at £2,550 / €2,799 / $2,799.99 for the Roscoe 9.

You can expect to find an improvement in component choice and performance as you increase the amount you spend. For example, the base-level Marlin 4 is kitted out with Tektro M280 mechanical disc brakes, whereas the top-spec Marlin 8 uses more powerful Shimano MT200 hydraulic disc brakes.

It’s worth noting that Trek’s recent overhaul to the Marlin frame only applies to models 6, 7 and 8, whereas models 4 and 5 retain the previous frame design to help keep these entry-level options priced competitively.

Another good example of how the components differ between models is the wheel and tyre setup. The entry-level Roscoe 6 uses tubeless-ready rims but not tubeless-compatible tyres, the Roscoe 7 features both tubeless-compatible rims and tyres, though set up with tubes, and the top two Roscoe 8 and 9 models are set up tubeless from the get-go.

The quality and configuration of drivetrains change significantly as you move up through the models. All of the third-generation Marlin hardtails, and all Roscoe models, use modern 1x drivetrains , while the second-generation Marlin 4 and 5 use a triple chainring and double chainring respectively.

Trek Marlin vs Trek Roscoe, so which should you choose?

Despite initial appearances as fairly similar alloy hardtails, the Trek Marlin and Trek Roscoe are actually very different machines.

Choosing between them largely comes down to what sort of riding you’re planning, and whether you’d like to prioritise versatility or are seeking all-out trail capability.

Want something that’ll make for a great first mountain bike for teens and adults alike, with the added versatility to take you across town to work and back, as well as to the trailhead? The do-it-all Marlin is the smarter choice.

Looking for a ride that’ll level up to meet you as you progress over larger, steeper and techier trail features? Kitted out with a dropper post, progressive frame geometry, wide, grippy tyres and a beefy 140mm fork, the Roscoe is Trek’s dedicated trail option. There’s a reason it’s dubbed the ‘hardcore hardtail’.

Once you’ve worked out which sounds most like you, then you have a choice of four or five models, each with their own component options. Spending more as you work up through the models will give improved performance, as well as a lighter build, which will only help to widen your grin once you swing a leg over.

Can’t afford the top model from the outset? The good news is that both the Marlin and Roscoe have been designed to be upgrade-ready when the time comes.
