With trail bikes in Trek’s lineup reaching five-digit prices, it is nice to see the industry giant offer a full-suspension trail bike that doesn’t break the bank. Trek was kind enough to send us the Fuel EX 5 to ride and review in our budget-bike shoot-out. At just under $2,500, the Fuel EX 5 is one of the most expensive bikes on test. We were excited to get the Fuel EX 5 out on the trails and see how it stacks up against the others in our test bike group.

ABOUT THE TREK FUEL EX 5

Many of us are familiar with Trek’s trail-busting Fuel EX line. The Gen 6 Fuel EX saw added travel – not to mention a new frame design – but that doesn’t mean there isn’t room for the shorter-travel younger sibling out on the trails. With 140/130mm of travel and relatively moderate geometry, the Trek Fuel Gen 5 has been a trail bike many have reached for years.

FRAME AND FEATURES

Trek’s Fuel EX 5 features Alpha Platinum Aluminum. Trek boasts their aluminum “is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.” The Fuel EX also has Trek’s Knock Block headset system, which prevents the handlebars from hitting the top tube and causing damage in a crash. Cables are internally routed, and the frame is offered in two color options: black, or the black and yellow we received.

The Fuel EX is offered in seven sizes, from XS to XL. X-small and small frame sizes come with 27.5-inch wheels and a pronounced dip in the top tube to help with standover height. Sizes medium and up are all equipped with 29-inch wheels. If you are familiar with Trek’s sizing, you will know that they also offer a medium/large size for those in between the two sizes. This is the only “in-between” size offered.

Trek’s Mino Link allows you to change the Fuel EX’s geometry. Switching from high to low will slacken the bike by 0.5°, drop the BB by 6mm, and shorten the reach by 5mm. While the bike comes with a 140mm travel fork, Trek gives allowance for bumping up to 150mm to improve descending capability.

The Fuel EX is essentially a linkage-driven single-pivot with one key difference—a pivot at the rear axle. Trek calls this their Active Braking Pivot (ABP) design. On most suspension designs, braking is considered to negatively impact the rear suspension’s ability to absorb impacts and provide traction. Trek’s ABP design aims to allow the rear suspension to remain more active under braking forces.

The Fuel EX 5’s geometry remains relatively moderate compared to today’s trail bike trends. For clarity’s sake, I’ll share the geometry in the “high” setting of the geometry-adjusting Flip Chip. The head tube angle is 66.5° and is paired with a 75.5° seat tube angle. The Stack Height ranges from 559mm to 623mm and Reach lengths range from 400mm to 500mm. Our size large came in at 609mm and 475mm respectively..

The BB height is 341mm in X-small and small, then 346mm for medium and up. Similarly, the BB drop is only 14mm below the axles on the two smallest sizes, and 28mm on sizes medium and up to account for the larger wheels. 436mm chainstays feature across all sizes. Our size Large Wheelbase totalled 1211mm.

BUILD SPECS

For the Fuel EX 5, Trek only offers two build options: a higher-end, 9.8 AXS Gen 5 and the budget-friendly EX 5 they sent us at $2,499. Leading the charge on our test bike was a Rockshox Recon Silver with the Motion Control damper and lockout. In the rear, there was a X-Fusion Pro 2 shock with “open” and “climb” positions.

The drivetrain is a complete Shimano Deore M6100 12-speed build, with Shimano’s 10-51 tooth cassette and a 30-tooth chainring. Shimano also handles the brakes, with 2-caliper hydraulic stoppers and 180mm rotors. 35mm width Alex MD35 wheels are laced to Bontrager hubs, and roll on wide 2.6 Maxxis Rekons. Bontrager makes up the rest of the build with tires, cockpit, and saddle—with the exception of a TranzX dropper post at a short 130mm drop length.

With a brand name as large as Trek, our expectations with the Fuel EX 5 were reasonably high. Even with a more budget-friendly component build, we figured Trek’s proven platform would shine through, regardless of the parts hanging from the frame.

When we tested the Trek Fuel EX 5 on the trails, we found it best suited for riders looking to put in miles. Its very moderate 66.5° headtube angle—the steepest of any of the bikes on test—puts the rider’s body more toward the front of the bike. This allows for a comfortable pedaling position, especially on climbs, which the Fuel EX 5 did reasonably well on. That forward-heavy position also provided good handling on the relatively techy bits of the climbs.

Even with a steeper headtube angle, the Fuel EX 5 wasn’t overly twitchy on faster descents. With 130mm of rear travel, it tackled some rough and chunky trails reasonably well, but finding its limit was quite easy for our aggressive riding crew. It also jumped decently, although the suspension had been firmed up quite a bit. This was done out of necessity, to add support to prevent harsh bottoming out on harder hits. Less aggressive riders looking for a more conventional light-duty trail bike may not feel the need to do the same.

One thing that seemed to hold the Trek Fuel EX 5 back while descending was the dropper post. Our size large EX 5 came with a 130mm dropper, a much shorter length than we’re used to for a size large frame. This meant having quite a bit less post insertion to get proper saddle height for climbing. When it was time to point the EX 5 downhill, the seat, even when dropped all the way down, was high enough between your legs to make handling the bike uncomfortable.

Initially, the expectation was that the Trek Fuel EX 5 might be the most efficient and best pedaling bike on test. However, we found that this wasn’t the case once we hit the trails. The bike’s geometry teased that as the case, but something seemed to be holding it back. After several of our testers spent considerable time on the Fuel EX, we concluded that the rolling weight of the wheels made the bike seem sluggish. We’re not sure why a trail bike is spec’d with 35mm inner width rims, but that, combined with 2.6 width tires, surely hurt the Trek’s performance when it came to rotational efficiency.

As with many of the other budget bikes in the field, the suspension and brakes were also where the Trek Fuel EX 5 came up short. The Fuel EX 5 shared the same suspension, and many of the same issues, as the GT Sensor Sport. The fork and shock both seemed sticky, and there were very few adjustments. The air pressure X-Fusion recommended for me (Travis) essentially turned the bike into a hardtail. When I let air out to get an appropriate SAG, the shock bottomed out hopping off a curb. Regarding brakes, the Shimano 2-pistons performed better than some of the other brakes on the budget bikes, but they still left us wanting a bit more power.

High value, high performance, and impressive versatility– those are three features many would love to see in a mountain trail bike. But does Trek Fuel Ex 5 hold up to its marketing in a review– or are there better options?

Trail mountain biking is nothing new. But in the past decade, trail mountain biking has steadily grown from a niche activity to one loved by many. You only need to look at 2020 mountain bike riding statistics to get a picture of just how impactful trail biking has become and what it means for many. 

Trail riding is unsurprisingly the most popular of all types of mountain biking , including enduro, downhill , and more. In a survey, over 92 percent of cyclists participated in the trail ride, a little over 56 percent in enduro, and 30 percent in downhill in 2 years. 

But what’s driving so many to hit the trails? Trail riding is the most accessible for new riders, requires less heavy-duty equipment, and poses a lower risk of injury vs something like downhill riding. Mountain biking of all forms is a means of exercise, exposure to fresh air, and enjoying the community. 

But even though the survey also indicated mental health benefits– with over 92 percent of respondents saying cycling helps balance negative emotions–there remains a barrier. Mountain biking is expensive, and not everyone can afford the equipment. But even if you can, you don’t want to overspend– and you also want to find a bike that will provide a smooth, stable ride.

That’s why I want to look at Trek Fuel Ex 5 , a trail bike that claims to be of great value. This guide will tell you my selection criteria for finding the best trail bike and review how Trek Fuel Ex 5 compares.

Fuel EX 5 is a full-suspension trail bike that's ready to handle it all. The Fuel EX 5 hits the mark as a high-value, high-performance mountain bike with exceptional versatility.

What is trail mountain biking?

When you think about mountain biking, you may picture steep inclines and declines and even jumps. But in between that rigorous biking and road biking is trail mountain biking. Trail riding is a general term that encompasses off-road riding.

Dirt and grass path away from a hectic life. Unlike with road biking, you’re not going to encounter cars– though you could encounter other cyclists if you pick a popular TRS that are most common, and they may feature twists, turns, and inclines or declines– but that isn’t the main focus.

The concept of trail riding is providing timail. You’ll contend with various terrain, and trail mountain biking is more challenging in terms of technique and balance– but also slower than road cycling. 

Is mountain biking a better workout than road biking?

Whether or not mountain biking is considered a better workout vs road biking, as you can imagine, is somewhat a matter of perspective. That is: how do you define a good workout? For some, it’s calories burnt. Others are worried about muscle gains or enjoyment.

All of these, and, of course, cardiovascular fitness, are valid factors. Mountain biking is more ideal for muscle development and a full-body workout. You’ll use more upper body strength, while road riding is mostly focused on lower legs and cardiovascular endurance. 

You can cover more ground more quickly road cycling, but the ground you’re covering riding on trails is more challenging. Holistically, mountain biking is considered a slightly better workout– with the added advantage of scenic and quiet locations. Still, road biking can be an excellent workout if you enjoy it more or if that’s simply what you have access to. 

Do I need a trail bike?

The first step is to assess whether or not you need a trail bike. Chances are if you’re considering a trail bike, it’s for good reason. If you already have a road bike it may be tempting to take it out on a trail- but that’s not a good idea. While bike categories may seem arbitrary, they exist for a reason.

Road bikes are typically made with a lightweight aluminum frame or other lightweight material, slim tires, and dropped geometry. A road bike is designed to reduce friction and optimize speed– so it’s not going to hold up well on uneven terrain. Road bikes simply don’t provide the traction and control you need for trail riding.  

What is the difference between a trail bike and a mountain bike?

Mountain bike is an umbrella term for many types of bikes. A trail bike is a form of a mountain bike, so it’s a misnomer to say the two are different. So instead, I want to take a look at specific bike types and how they compare with a trail bike. 

What is the difference between enduro and trail MTB? 

Enduro mountain bikes are hardy bikes designed for downhill riding. They’re notable for their long travel and also accelerate at steep inclines. Enduro bikes are bulkier than general trail mountain bikes but are also more efficient, designed for trail racing competitions. You should get an enduro if you plan on racing or want to take on steep descents and inclines.

If you just want to ride recreationally on moderate trails, a trail bike will save you money, storage space and is a bit easier to learn how to ride.  All-mountain bikes are included in the general category of enduro (which refers to racing), so the differences between trail and all-mountain bikes are the same as for enduro. 

What’s the difference between a trail bike and a motocross bike?

Motocross bikes have a very specific purpose. These bikes are a form of a motorcycle and are ridden on muddy tracks with controlled conditions. Not only are they motor-operated, but they also feature bulky tires and handlebars and are bulky.

Dirt bikes are in between– nonmotorized bikes meant to tackle muddy conditions with knobby tires and a heavy frame. Trail bikes are far lighter and a bit more versatile, meant to tackle different trial types, and also designed for riding in fair to moderate conditions. 

What’s the difference between XC and trail?

XC, or Cross Country , is a popular mountain bike type known for its versatility. XC bikes are ridden on trails and roads, making them a great crossover bike– though they’re more efficient on trails and not meant as a replacement for road bikes. It depends on the model you’re looking at.

Still, XC bikes are more lightweight and accelerate more easily than your average trail mountain bike. XC bikes are used for tortuous paths, but they’re not equipped for climbing or descending as much. XC bikes are used more for racing, while trail bikes are used for general rides and focus on control and greater shock absorption. 

What is a trail bike good for?

A trail bike is the most popular type of mountain bike for a good reason. It’s less specialized than other mountain bikes and can be used for most trails. Trail bikes can climb up or descend, though they aren’t intended for racing or especially steep inclines and declines or as inclement weather. Think of a trail bike as a recreational bike that’s harder than a road bike and offers more stability than a racing XC bike. 

Can you jump a trail bike?

Technically you can jump just about any bike, but there are bikes designed for jumping. Trail bikes are not a great option for jumping, as they don’t have the acceleration and inertia to get much air. And while they offer control, that control isn’t designed for performing jumps. At most, you could do some modest jumping. If your main objective is to find a bike for jumps, I recommend a dirt bike. 

Can I take a trail bike to a bike park?

While trail bikes are more versatile than some mountain bikes, they aren’t designed for road or bike parks. Trail bikes do perform at their best on trails. 

Can you use a trail bike for downhill?

Trail bikes climb and descend efficiently. They offer control, but they’re not meant for the very steepest trails, nor are they designed for purely downhill biking. The key here is to understand that trail bikes value control over speed.

You can’t expect to do downhill racing, but a good trail bike can handle inclines and declines. 

How do I choose a trail bike? ( My Buying Criteria)

If you’ve decided that a trail bike is the right type of bike for you, make sure that you find a bike that’s going to last and provide stability. Before I review Trek Fuel Ex 5, here’s a succinct guide to my selection criteria for finding a great trail bike. 

What trail mountain bike size should I get?

Determining the right size is important for comfort and control, but it can also be tricky. Different brands have different sizing standards. Smaller frames or sizes may vary from manufacturer to manufacturer, so the best idea is to refer to that brand’s sizing guidelines. Click Here for Trek Mountain Bike Sizing . 

How important is bike standover height and the top tubes?

Another sizing consideration is the standover height. A bike’s standover height refers to the length of the top tube to the ground and most commonly included within sizing information. This is important and also can lead to a better fit.

A standover height that’s too great can risk injury, while a too short height can leave you feeling cramped. For straight handlebars, I recommend an inch to two inches of clearance

. This provides a good fit and proper visibility. A sign a bike is too small is if you’re sitting on the bike and easily able to touch the ground with your feet.

Is a 27.5 or 29er tire better for a trail bike?

For the tire size, your most common options are a 27.5 vs a 29er. Both are fine, but I mean more towards a 29er for a trail bike. A 27.5 tire is generally more efficient at accelerating, but a 29er is going to provide a bit more traction and control.

But size isn’t the only factor in finding the best tire type. A dual compound improves durability. You’ll want a tread pattern that offers grip and traction for turning corners and some sidewall support. Puncture resistance is ideal for trail riding too. 

What material is best for trail cycling?

You’ll have an option of aluminum, carbon, steel, and titanium for most mountain bikes. Of these, I’d recommend carbon the most for a trail bike. While titanium is a bit smoother and lasts just as long, it does get quite pricey, and may not be necessary for a trail bike.

Carbon is lightweight and, unlike steel, not prone to corrosion. Aluminum is attractive for being lightweight and budget-friendly– but I’d prefer aluminum for something like a road bike, as it’s more prone to damage. 

How many gears should a trail bike have?

Considering that mountain bikes can have up to 40 gears, it can feel like you need as many gears as possible, but that’s not the case. For a solid trail bike, I recommend around 20-27 gears.

This provides more control and versatility- needed for trail riding– but doesn’t require you to search long and hard and pay top dollar. Aside from the number of gears, also pay attention to the type of gears.

You’ll also have the option between single, double, and triple drivetrains. 

Of these, I recommend a double drivetrain. It’s a nice balance for a trail bike. You’ll have situations where you may need more than a single, but you also aren’t using a trail bike the same way you would an enduro bike. 

Are disc brakes better on a trail mountain bike?

Between disc brakes and rim brakes, I recommend disc brakes for trail bikes. They’re smoother, more reliable, and less likely to become damaged when riding on trails. Some even consider a bike on a trail without disc brakes to pose safety hazards– I’d consider this feature nonnegotiable.

But you will need to decide between mechanical vs hydraulic brakes. Hydraulic brakes use fluid for stopping power, while mechanical brakes are purely based upon traditional brake chain force. Hydraulic brakes tend to be smoother and more expensive, and they’re quicker to respond.

I prefer hydraulic brakes for a trail bike, especially if you get caught in inclement weather. That doesn’t mean mechanical brakes are bad– they’re just not as efficient. 

Is a hardtail mountain bike good for trails?

Full suspension tech is better for a trail bike if you have the money, though you can argue it’s not a must-have. With the full suspension, you’ll get both rear and front shock, equipping the bike with greater traction, steering control and making for a more comfortable ride for bumpy trails

. You’re adding weight and cost, but for many, those trade-offs are well worth it, especially since trail bikes aren’t intended for racing and quick acceleration. With a hardtail, you have a rear shock and a lighter setup. If you opt for a hardtail bike, I recommend sticking to even trails. If you’re doing fairly light trail riding, a hardtail may be just fine. 

How much travel do you need for trail riding?

Bike travel is measured to determine the distance from the front or rear suspension that will absorb force. Thus, the greater the travel, the more shock resistance.

Bikes with greater travel may not accelerate as quickly, but they provide a smoother, more controlled ride for uneven trails. 100mm is the minimum I’d go, but 120mm to 130mm is a great range.

Above 140mm isn’t necessary for a general suspension trail bike. 

How much is a trail bike?

As you can imagine, the price of a trail bike ranges depending on materials, construction and brand. Trail bikes are more expensive than road bikes, but they’re also less expensive than something like an enduro bike.

You’re unlikely to find a trail bike that quality features for under $1,500, but spending a bit more leaves room for some great upgrades. 

Are dropper seatposts worth it?

Dropper posts are sometimes used for mountain bikes to provide greater adjustments than your Seatpost. This can provide greater visibility and comfort, and for some avid cyclists, it’s worth it. However, for a trail mountain bike, it’s not usually necessary. 

How do I choose the right mountain trail bike seat?

There is no perfect saddle for a trail bike seat, as we all have different bodies and different personal preferences. There are three general categories for mountain bike saddles: performance, racing, and recreation.

Since trail bikes aren’t used for racing, opt for a recreation saddle, or a performance saddle if you like a little versatility. You’ll want some cushioning and shock absorption, with gel offering the best cushioning and foam second.

A synthetic material like nylon that’s weather-resistant is wise for a trail bike. A center cut-out will provide a lighter profile and some breathability. Still, a saddle without a cut-out has more overall cushioning. 

What is Trek known for?

Now that you know my criteria for finding the best trail bike, I want to examine Trek as a brand. If you’ve considered buying a mountain bike before, chances are you’ve heard the Trek name, and for a good reason. Trek is one of the most popular makes for mountain bikes of all kinds.

Trek is also known for its wide selection of entry-level bikes, which some competing brands don’t offer to the same extent. That is of course tied to the fact that Trek is the largest US-based cycling company. The Roth Distributing Company owns Trek. 

Where are Treks made?

Up until 2017, Trek bikes were all manufactured and shipped from Waterloo, Wisconsin. Now they outsource some of their manufacturing to Asian countries, so none of their bikes are fully made in the United States. 

Is Trek a good movie?

Trek retains its reputation as a solid brand for entry-level and more specialized mountain bikes. One way they’ve done so is by staying on top of new biking technologies while still offering bikes at an accessible range of prices. Their diverse inventory and willingness to improvise both highlights why Trek bikes remain well regarded and popular. 

How long does a Trek bike last?

Trek bikes don’t all last the same time because that depends on the materials used and how heavily the bike is used. There’s so much variability– for all brands– for these and other factors that it can be difficult to estimate.

While most Trek bikes are well made, you’re not guaranteed that a bike will last a certain length of time. Regular bike maintenance is critical for whatever model you purchase. 

Is the Trek Fuel Ex 5 Worth It?

Trek Fuel Ex 5 is a striking but approachable bike, marketed as a high-value and high-performing option. With a dropper post and other great features, is it all hype or worth your money?

What type of bike is the Fuel Ex 5?

The Fuel Ex 5 is a mountain trail bike equipped with a blend of higher-end and accessible materials and features. It’s touted as a gateway to a mountain bike. The wording makes me think that the Fuel Ex 5 is trying to cater to those new to mountain or trail biking, or perhaps those who want great features but not at an eye-watering price point. 

How much does a Trek Fuel Ex 5 cost?

Still, the price is higher than some trail bikes by a good $1,000, so it’s important to investigate every feature offered. Prices are subject to change and vary based upon your make and specifications. Still, you’re looking at spending roughly $2,500 as of the end of 2021/ early 2022. 

What material is the Trek Fuel Ex 5 made out of?

The Trek Fuel Ex 5 features a lightweight aluminum frame, which surprised me for a few reasons. For one, at the price point, I expected perhaps a carbon fiber frame. But it also is a little heavy for its make.

Aluminum isn’t a terrible choice if you’re starting suspension trail riding. It is reasonable for moderate trails– but it can dent and become damaged by impact and debris. I do appreciate that aluminum won’t easily rust. 

How much does a Trek Fuel Ex 5 weigh?

The Trek Fuel Ex 5 comes in at 34 pounds and 6 ounces for medium frame size. This is interesting because the average weight for a full suspension trail bike with an aluminum body is between 29 and 33 pounds.

This makes the Trek Fuel Ex 5 a bit heavy for what you’d expect, especially considering it’s not a full-suspension bike. I would argue this isn’t the biggest problem for a trail bike, but it still should be noted.

Your ride will feel a little less springy than you might expect from an aluminum body. 

How much travel does a Trek Fuel Ex 5 have?

Here’s where the Trek Fuel Ex 5 shines: the travel. You get an impressive 140mm of travel, providing a smoother and more controlled ride. This is generous for a general trail bike, and an advantage over some competing bikes. 

Does the Trek Fuel Ex 5 have a dropper post?

The Trek Fuel Ex 5 likewise has a dropper post. By opting for a dropper post, you’re getting more versatility out of your seat positioning, as well as offering a slight advantage for visibility. While not a must-have, it’s a nice feature to have if you know how to use it effectively. 

What kind of drivetrain does the Trek Fuel Ex 5 have?

Trek Fuel Ex 5 has a Shimano 1×12 drivetrain. You’re getting 12 gear speeds and a single cassette. The 12 gears are sufficient for a trail bike for moderate trails, even if it’s not as generous as some models.

Shimano is a respectable brand and usually makes quality products. Their 12-speed drivetrain provides a stable and clean stop with new Hyperglide technology that’s meant to improve the single drivetrain experience.

For a single drivetrain, it’s a solid option, but I do wish they added a double drivetrain. 

What type of brakes does Trek Fuel Ex 5 have?

Hydraulic disc brakes are used for this model, which is a great upgrade for a mountain trail bike. The breaks are also manufactured by Shimano, which is another plus.

Is the saddle comfortable on the Trek Fuel Ex 5? 

The saddle is a Bontrager Arvada . This is a performance saddle seen on both road and trail bikes and is made with microfiber. Microfiber is known to be lightweight and fairly durable. While it’s not fully weather-resistant, it can repel water.

The rail is made out of steel, which is strong but also can corrode over time. The cut-out is designed for pelvic rotation and is focused on balancing comfort and efficiency.

It’s a reasonable saddle choice– not a stand-out, but suitable for regular trail riding. 

Arvada Comp adds comfort and reduces soft-tissue pressure by creating a strategic cut-out in the saddle shell. 

What are the tires like for Trek Fuel Ex 5?

The tires are a  27.5” Bontrager XR4 Comp , with a 30 TPI. The size is designed a little more for acceleration than traction. 30 threads per inch for the tire is on the low end. Utility tires are around 15 tpi, while the high end may be 120 TPI.

For general trail riding, you want a tire that falls between 60 and 120 TPI, and it is always a trade-off and balance. The highest tapis has less rolling resistance, while the lower end is less likely to puncture.

If you do buy the Trek Fuel Ex 5, you may want to consider if you can swap out the tires for a bit higher tpi. 

The XR4 Team Issue TLR tire offers incredible grip and fast-rolling efficiency in a new and improved tread pattern with 120 TPI casing. Save yourself from punctures with our Inner Strength sub-tread protection while squeezing out every bit of cornering traction with the 61a/50a dual-compound rubber. 

Frequently Asked Questions

Answer: This depends on the model you’re considering. If you look at a newer model of both, you’ll be getting a carbon body with either bike. They also both feature full suspension for a general mountain bike. The main difference is that the Trek Fuel Ex 9.7 and the Top Fuel 9.7 are in the wheels, travel, and gear capabilities. The Top Fuel comes with either 27.5 or 29ers, while the Top Fuel Ex has 29ers and more gear capabilities. The Ex is better for a trail bike, while the Fuel could be argued for as an XC bike. 

Answer: Ther Trek Fuel EX 9.8 features a carbon frame and weighs 28.94 pounds for a medium frame. 

Answer: This Trek model is a versatile trail bike with a platinum aluminum frame and 150mm travel. It weighs 31.92 pounds for a medium frame. 

Final Thoughts

The Trek Fuel Ex 5 has some great features going for it: hydraulic brakes, a dropper post, impressive travel, a respectable saddle, and well-designed gears. It is a bit limiting in other ways.

For example, an aluminum body frame but a heavier than average weight and low TPI tires make this bike a bit mixed in terms of features. It’s a decent bike for general light to moderate trail, and what’s here is mostly well done– I do wish it was a little cheaper.

2020 Trek Fuel EX ditches Full Floater suspension, gets progressive geometry and onboard storage

The trail-orientated Fuel EX gets a modern makeover to appeal to more riders with a broad range of build kits and new features

The new Trek 2020 Fuel EX has been designed from the ground up, ditching the brand's signature Full Floater suspension system, adopting more progressive geometry, gaining onboard storage and getting a more broad selection of build kits to suit all budgets.

First launched nearly 15 years ago, Trek’s Fuel EX has somehow managed to span the range of being an entry-level mountain bike while at the same time appealing to hardcore all-day epic trail riders.

• Marin Rift Zone 1 review

Since the bike first launched we’ve seen plenty of changes in the range including suspension technology and travel — initially the bike was offered with just 100mm of travel, growing over its lifespan and the bike’s seen the addition of Trek’s different suspension technologies such as the Full Floater, RE:aktiv, Mino Link and Thru Shaft.

Geometry trends have changed, too, and the Fuel range has reflected this. Starting out as an XC-orientated bike, the Fuel EX has morphed into something that’s likely to be more at home on a wider variety of trails. Trek even mention the ‘e’ word in its marketing spiel — yes, the Fuel EX even has enduro riders in its sights.

2020 Trek Fuel EX updates and changes

What has Trek changed on the new model, then?

2020 Trek Fuel EX geometry

In the same way riders chase the proverbial perfect trail, most bike companies are chasing the longer, lower and slacker mantra with their bikes. Trek’s new Fuel EX is no exception to that rule.

Aiming to appeal to more riders, and quite possibly more extreme riders, from the outgoing model the bike’s gained a 10 to 20mm reach increase (depending on size), a 1-degree slacker head angle taking the figure down to a respectable 66 degrees and, most impressively yet, a steeper seat tube angle that’s climbed to 75 degrees.

• What’s the future of MTB geometry?

These figures should mean the bike’s more at home when you’re riding harder and faster — offering a more stable chassis. There’s no detrimental effect for beginners, either, who’ll reap the benefits of a bike that doesn’t feel like it’s jumping around like a cat on a hot tin roof.

There’s also a broad range of sizes that start at extra small, running through to extra-extra-large. In the range, there are two small sizes: one for 27.5-inch wheels and one for 29-inch wheels.

In a welcome move, a medium and a medium-large size also rear their head. This bridges the gap between the medium and large bikes for people who’d normally sit between the sizes. Top work, Trek!

You also get a high and low setting thanks to Trek’s Mino Link flip-chip that’s located on the seatstay to rocker link. Changing from low to high adjusts the head angle from 66 to 66.5 degrees, the seat tube angle from 75 to 75.5 degrees and reduces the bottom bracket drop, shortens the chainstay and the wheelbase among other numbers.

• Seat tube length: 450mm
• Seat tube angle: 75/75.5 degrees (low/high)
• Head tube length: 105mm
• Head tube angle: 66/66.5 degrees (low/high)
• Effective top tube: 634/633 mm (low/high)
• Bottom bracket height: 346mm
• Wheelbase: 1,211/1,210mm (low/high)
• Standover: 748/754mm (low/high)
• Reach: 470/754mm (low/high)
• Stack: 613/609mm (low/high)
• Notes: Measurements for size large bike, full measurements available on Trek's website .

2020 Trek Fuel EX frame details

Not only has the bike’s geometry been modernised — Trek has also worked hard to accommodate the modern, discerning mountain biker.

You can now fit a 29 x 2.6-inch tyre on the back of the bike and Bontrager XR4 2.6-inch wide rubber is standard on all models of the Fuel EX.

Trek has also managed to increase the range of dropper travel possibilities on its bikes. The extra-small and small bikes get 100mm travel posts, while the medium and medium-large bikes have a 150mm travel post. The large, extra-large and extra-extra-large sizes are treated to a 170mm post.

In another welcome move, the Fuel EX gets on-board storage in the bike’s down tube. The storage’s hatch doubles up as a bottle cage and every Fuel EX is supplied with a Bontrager tool roll that’s got handy compartments to store your bits and bobs — a similar system was adopted on the very recently released Trek Domane road bike .

The Fuel EX comes in two materials: a cheaper alloy version and a full carbon affair that has a carbon mainframe, seat and chainstays. The carbon model gets a dedicated down tube protector, too.

You’re also treated to Trek’s Knock Block system, which physically stops the bars turning beyond a certain angle to stop the bars, shifters or brake levers and fork crowns damaging both the top or down tubes.

There’s Trek’s Control Freak internal cable routing throughout that’s also Di2 compatible, so if you’re looking to upgrade in the future you’ve got the option of doing away with antiquated analogue gear shifting.

Trek also states that all of its Fuel EX bikes have a lifetime warranty.

2020 Trek Fuel EX suspension details

In a rather bold move Trek has done away with its signature Full Floater suspension system that has been seen on the Fuel for some years. This arangement mounted the shock to both the linkage and the chainstay in front of the main pivot, which meant that the shock didn’t have a fixed mounting point — as the suspension compresses, so did the shock’s relative position.

Now, though, the rear shock mounts to a fixed point on the down tube at the junction of the seat tube, like traditional suspension designs.

Trek claims that doing away with its Full Floater technology means that the frame can be stiffer, tyre clearance can be increased and there’s no loss in suspension performance.

It's worth noting that, at the time it was used on the bike, Trek claimed that its Full Floater system meant that the shock’s leverage ratios could be soft off the top, give plenty of mid-stroke support and help increase bottom-out resistance. It also claimed that a Full Floater bike felt like it had more travel than it actually does.

To then go on and claim that there’s no loss in suspension performance after doing away with this system begs the question of why it was implemented in the first place.

Trek’s Active Braking Pivot (or ABP for short), unlike the Full Floater, avoids the chop on the latest Fuel EX. And like previous iterations of Trek models with the system, it claims it helps to increase suspension performance under braking.

The Fuel EX 9.8 and 9.9 models are adorned with the stiffer, burlier Fox 36 fork that hints at the bike’s capabilities and intended use. The rest of the range gets a mix of Fox 34, RockShox 35 Gold and Recon forks so there’s a good balance of intended use in the range.

Except for the Fuel EX 5 and 7, you get Trek’s RE:aktiv suspension technology on the whole range. This, Trek claims, helps to be supple on small bumps and push deeper into the travel, but is firm while you’re pedalling without having to flick levers.

From the 9.8 model upwards, you also get Thru Shaft technology. This is where Trek has got rid of the internal floating piston in the rear shock, creating a system where there’s no oil volume displacement as the suspension compresses and extends.

2020 Trek Fuel EX women’s specific models

Trek’s also launching a full range of women’s specific models that will feature two colourways on all models, a wide range of sizing options, including two small sizes with the choice of 27.5- and 29-inch wheels, and plenty of standover height.

2020 Trek Fuel EX pricing and availability

"A world-class trail bike"

"Fuel EX is a beautifully balanced and capable trail bike. The rear suspension is beautiful; as close to ideal as any bike I've ridden. It's sensitive where you want it to be, firm and crisp where it should be. It feels deep and controls big hits very well, and there's a nice platform for pedaling, and to pump and pop off when you're playing."

"Good at pleasing everybody"

"Fuel EX has a few tricks that help it keep a level head when outside of its comfort zone, and to be a cloud on rails when it's in the zone. Everything about the Fuel EX, which was already good at pleasing everybody, is now even better at it."

"An absolute trail rocket"

"Thanks to its burlier components, increased travel, and more aggressive geometry, it has become more of a shredder than ever! More performance, fun, and trail prowess."

Trek Fuel Geometry - Suspension set High

How to measure yourself, measure your height.

Our handy size charts match your height to the appropriate frame size so you need to be sure you’ve measured your height accurately.

• Take off your shoes and stand with your back against a wall.
• Make sure legs are together and your shoulders are back.
• Place a pencil on top of your head and mark the wall (the best and easiest way to do this properly is with a friend to help you).
• Measure from the floor to the pencil mark you have just made with a tape measure.

Range of Reach

For most people to get the right frame size, measuring your height will suffice. However, you may find that your height is on the borderline of the range we suggest for a particular frame. If this occurs you need to measure the range of your reach or “Ape Index”. This will ensure you get a comfortable distance between the handlebars and your saddle.

• Stand up straight with your back against a wall.
• Life your arms out horizontally either side of you.
• Measure the distance from fingertip of one hand to fingertip of the other. This will give you your arm span.
• Subtract your height from this figure to get your Ape Index.
• If the result is positive (your arm span is greater than your height) you should go for the larger size of bike.
• If the result is negative (your arm span is less than your height you need the smaller size.

Stand Over Height

You should also consider your inside leg measurement when choosing your bike to ensure adequate stand over height. Stand over height is the clearance between the top tube and the bottom of your crotch. For mountain bikes we recommend a distance of 2-4 inches and for road or hybrid bikes 1-2 inches of clearance is required. This will ensure comfort when you’re stopped and standing astride the bike.

Our bike sizing charts take stand over height into consideration but if you have a particularly long or short inside leg measurement in relation to your height you will need to bear this in mind when selecting your frame size.

Riding Style

The way you ride and the type of bike you are into will also impact the frame size you should choose. For example, a trail devotee looking for an aggressive ride may prefer a smaller, more manoeuvrable bike size. It all comes down to personal preference and how the bike feels to you.

Our sizing charts aim to be as specific as possible so you can look up the particular type, make and model of bike you’re looking for. Remember, the sizes given in our guides are suggestions and should be used for general advice only. For the best possible fit  we recommend popping in to your local Leisure Lakes Bikes store, or call 0800 083 0888 for expert advice tailored to you.
