Review of Trek Domane SL 5: Carbon Road Bike for Endurance Rides

Trek Domane SL 5 is a step up from an entry-level carbon bike, featuring high-quality components and Trek’s patented IsoSpeed frame.

Trek’s Domane SL 5 carbon road bike features its unique 500 Series OCLV Carbon frame with front and rear IsoSpeed to absorb shock and reduce fatigue.

The IsoSpeed system is the result of years of research and development to create a frame with unprecedented comfort and maximum efficiency.

The Domane range of carbon road bikes is slightly heavier than typical carbon frame racing bikes due to the additional strength and comfort features.

These include thicker tires, heavier rims, and hydraulic brakes.

Trek Domane SL 5 Quick Overview

Main features, is the trek domane sl 5 the right choice for you, is it worth the money.

Trek Domane SL 5 Gen 4 is fitted with high-quality, lightweight components that complement its OCLV carbon frame.

This, coupled with IsoSpeed technology, makes for a surprisingly tight yet smooth ride. 

• Frame : 500 Series OCLV Carbon IsoSpeed
• Fork : Domane SL tapered carbon steerer
• Front Derailleur : Shimano 105, R7000
• Rear Derailleur : Shimano 105, R7000
• Rims : Bontrager Affinity Disc Tubeless Ready
• Number of Gears : 22
• Brakes : Shimano SM-RT70
• Tires : Bontrager R3 Hard-Case Lite, aramid bead, 700x32c
• Weight : 19.69 lbs / 8.93 kg

Get From Trek

Rather than just a well-equipped carbon frame bike, the Domane SL 5 fits together specific features to create a light and comfortable road bike that can also tackle rough terrain.

The carbon IsoSpeed frame is supported by a Shimano 105 groupset and hydraulic disc brakes.

IsoSpeed carbon frame

Trek’s IsoSpeed system features front and back decouplers with a rocker cup that allows flex in the seat tube and steerer tube.

This helps to provide a smooth ride without losing solid road contact and stability.

The frame uses optimized endurance geometry to give the rider a confident, controlled feeling in the saddle.

When it comes to carbon frames, its 500 Series OCLV is on the heavier side which is most noticeable on hills. However, it makes up for this but cutting through bumpy surfaces with ease.

Performance Cable Routing

The rear gearing and brake cables are internally routed through the bike’s carbon body, keeping the frame neat and clean.

This not only protects the cables but makes everything more attractive and aerodynamic.

Unfortunately, the front disc brake cabling is not routed through the fork, leaving a rather untidy zip-tie solution running down the left fork.

An odd choice for a road bike in this price range but it works just as well, albeit a bit less easy on the eye.

Shimano 105 groupset

Trek’s decision to use Shimano’s 105 groupset for the Domane SL 5 was an excellent choice and suits its high-quality carbon frame.

The complete Shimano groupset includes the shifters, chain, hydraulic brakes, front and rear derailleurs, and an 11-speed cassette.

The complete set works together to provide excellent, fault-proof mechanics and seamless operation that lets you focus on the road ahead.

Shimano 105 is one of the most reliable drivechains available and has been a firm favorite of cyclists around the world for decades.

The Domane SL 5 incorporates Bontrager Paradigm rims for their strong, durable nature.

Wrapped around the Domane SL 5’s Paradigm rims are Bontrager R3 Hard-Case Lite 700x32c tires.

The extra-large tires are an unusual choice for a carbon road bike, further solidifying its purpose as an all-terrain machine.

Endurance geometry

The endurance geometry used in the Domane range of road bikes is designed for long-distance rides, with a slightly higher headtube.

It attempts to balance speed and comfort, providing a more relaxed seating position than is commonly found on carbon racing bikes.

The sloping top tube reaches the seat post at an angle that makes it appear to move almost continuously into the seatstays.

The thicker-than-usual downtube also has an ever-so-slight bend that creates an appealing profile view.

It’s a marriage of technical perfection and high-quality materials to deliver a truly unique carbon frameset.

The Trek Domane SL 5 comes in 9 different sizes to fit heights of 4’11 to 6’2.

• 44 : 4’11” – 5’0″
• 47 : 5’0″ – 5’2″
• 50 : 5’2″ – 5’4″
• 52 : 5’4″ – 5’6″
• 54 : 5’6″ – 5’9″
• 56 : 5’9″ – 5’11”
• 58 : 5’11” – 6’1″
• 60 : 6’1″ – 6’3″
• 62 : 6’3″ – 6’5″

Trek’s Domane SL 5 is a serious carbon-framed road bike for dedicated riders looking to cover long distances on a regular basis.

It would suit semi-professional cyclists and triathletes looking to train regularly for competitions and events.

Sure, if you’re just a weekend rider and can afford it, you’ll love it.

However, a bike of this quality deserves to be put through its paces by those aiming for the podium.

It’s tough, fast, comparatively light, and most importantly: it provides a beautifully smooth ride.

High-quality carbon frame: check.

High-quality Shimano components: check.

A price tag under $3,500: check.

I would say, yes, the Trek Domane SL 5 is most certainly a piece of equipment that ticks all the right boxes to offer excellent value for money.

There are faster and lighter carbon road bikes in a similar price range, and there are tougher bikes too, but none of them find the balance quite as well as the Trek Domane SL 5 does.

This is a long-lasting bike that will seldom require any repairs or upgrades.

Trek Domane Generation Four—What is New

My biggest knock against the third-generation Domane was the weight. It was an excellent and feature-rich bike but a little hefty. So, I am happy to report that one of the most significant changes to the fourth generation frame is it is lighter by about 300 grams (more than half a pound. A large part of the weight savings came from simplifying the bike’s signature rear IsoSpeed Decoupler and eliminating the IsoSpeed Front system that debuted in the previous generation Domane.

When asked why Trek eliminated IsoSpeed Front, Jordan Roessingh, director of road bikes, stated that much of the system's benefit—which never offered the same compliance improvement as rear IsoSpeed—was made redundant by riders' increased adoption of higher volume tubeless tires run at lower pressures. Combined with the system’s weight penalty, Trek decided the juice was not worth the squeeze and punted IsoSpeed front into the dustbin of history.

Meanwhile, at the rear, Trek removed the adjustment from the SLR’s top tube IsoSpeed. All frames now have fixed compliance. Reggie Lund, a design engineer at Trek, said that it found, “A lot of our riders were never taking advantage of the adjustability on the previous generation bike,” so they decided to remove the feature which simplified and lighted the frame. Roessingh stated that the new Domane’s fixed compliance is in line with the previous generation SLR’s IsoSpeed set to the most compliant position.

SL-level frames also see a change to their rear IsoSpeed system. Trek has multiple iterations and generations of IsoSpeed. While third-generation Domane SLR frames had adjustable top tube IsoSpeed, third-generation Domane SL frames had non-adjustable seat tube IsoSpeed. SL and SLR fourth generation Domanes get the new non-adjustable top tube IsoSpeed.

Roessingh said that one of the drawbacks of the third-gen Domane’s non-adjustable seat tube IsoSpeed was that the system got more rigid as the seat tubes got shorter. In short, smaller and likely lighter riders experienced a rougher ride than larger riders. Top tube IsoSpeed eliminates this compromise and lets Trek tune compliance per frame size, said Rosseingh, so all riders experience similar levels of comfort.

Another signature feature of carbon framed Domane models that went to the dustbin was Trek’s No Cut semi-integrated seat mast. Instead, all models now use a seat post, although a proprietary D-shaped post instead of being round. Thankfully, Trek offers two lengths (280 and 320mm) and two offsets (five and 20mm) to help riders dial in fit. The seatpost clamp hides under a snap-on cover on the top tube, which helps clean up the lines of the new Domane.

Another way Trek cleaned up the Domane’s appearance is with a new stem with a cap that hides the hoses and housing before they enter the frame through the upper headset cover. But while the bike appears to have fully integrated routing, you can swap stem lengths without pulling the hoses or housing. The bike is compatible with a standard handlebar, and riders can use standard stems. However, if you want to install a standard stem, you will need to acquire a different upper headset cover from Trek, and you will probably want to zip-tie your hoses and housing together underneath the stem.

Trek’s Domane stem comes in sizes 60 to 130mm in minus-seven degree rise and 60 to 100mm in plus-seven degree rise. The faceplate features a single bolt mount for a computer/light/camera. Unfortunately, the Domane stem’s one-bolt mounting standard is different from Trek’s one-bolt mounting system for the Madone and Emonda and also different than any of the other stems with this feature (3T, Cervelo, Fizik, Specialized, Felt, Easton).

Trek also states that the new Domane is more aerodynamic than the previous generation due to the updated shape of the fork, downtube, seat tube, seat stays, and more-integrated cables in the front. However, Trek did not provide any data on the aerodynamic improvements. When I asked Roessingh for time or watt improvements, he told me, “I don’t think we have a specific claim other than saying we do know the bike is faster. But it’s not a huge amount so it’s not a claim we’re labeling as one of the headlines of the launch.”

One small new feature added to the Domane is a mount in the top tube for a feed bag. What has not changed is the Domane has clearance for up to a 38mm tire, hidden fender mounts, the threaded (T47) bottom bracket, and the in-frame storage accessed through the hatch in the downtube.

SL and SLR frames are compatible with mechanical drivetrains. But, there is a catch outlined in Trek’s FAQ, “The frame does not have a front derailleur housing stop, which means that you are limited to front derailleurs with a built-in stop, like Shimano toggle front derailleurs.” That means the frame is not compatible with SRAM or Campagnolo mechanical-shift drivetrains.

Trek Domane Four—SL Versus SLR

There are two grades of Domane frame: SL and SLR. According to Roessingh, “SL and SLR are essentially identical from a feature set perspective and frame shape perspective.” The biggest difference is the carbon: The SL uses Trek’s “500 Series” carbon while the SLR uses “800 series” carbon. That material difference results in a 200-300 gram reduction in frame weight. According to Trek, this puts the SL frameset at 2,500 grams and the SLR frameset around 2,200 grams.

Trek Domane Four—RSL for the Racers

Although Trek’s professional racers ride a Domane in some events, typically the cobbled classics, they do not ride the standard frame. Instead, they use the Domane RSL (Race Shop Limited). It is the frame ridden to victory in the 2022 Paris-Roubaix Femmes by Elisa Longo Borghini , and it has a few notable differences from the mainline frame.

The primary distinction is fit. The RSL fame is much lower and longer than the SL and SLR Domane. Using a 56cm frame as an example the RSL’s reach is 21mm longer (395 versus 347mm) while the stack is 43mm shorter (548 versus 591mm). The RSL also has a much shorter trail length (51mm compared to 61), likely because of the increased weight the RSL’s geometry places on the front wheel.

Other changes include eliminating the top tube bag mounts and in-frame storage hatch—you do not need those things when you have a fleet of team cars behind you—and the fender mounts. These changes help shave weight off the frame compared to the standard Domane. The RSL frame also has less tire clearance—its maximum tire width is 35mm instead of 38mm—but will fit larger chainrings (RSL: 2x 54/40, 1x 54T; SLR and SL: 2x 52/36, 1x 50T) than the SL and SLR models. Another noteworthy difference: The RSL is only compatible with electronic shifting.

Trek only offers the RSL as a frameset ($4,200) and only in sizes 52 to 60cm, four fewer sizes than the mainline frame. Claimed frameset (frame and fork) weight is 1600 grams for the RSL. On paper, that makes the RSL a whopping 600 grams lighter than the SLR. But when I fact-checked that weight delta with Roessingh, he told me, “The way we measure ‘frameset” weights in those metrics isn’t apples to apples. It includes a bunch of hardware and components. The RSL frame weight is only about 100g lighter than the SLR’s.”

Trek Domane Mk.IV—Geometry

Most of the Mk. IV Domane models carry forward the Mk. III’s endurance geometry with no changes. It is a shorter reach and a taller stack fit, with a longer wheelbase and mellower handling than a race bike. Trek offers nine sizes, from 44 to 62cm.

The RSL version previously mentioned features a lower and longer fit race fit that is even more aggressive than the Madone and Emonda race bikes with the brand’s H1.5 geometry. The RSL is only offered in five sizes, from 52 to 60cm.

Trek Domane Mk.IV—Builds, Prices, and Weights

Trek’s rolling out the new Domane with 11 models: five SL builds priced between $3,500 to $7,500 and six SLR models priced at $8,000 to $13,200. Only one model, the $3,500 SL 5, has a mechanical shifting drivetrain (Shimano 105); all the rest have electronic drivetrains from Shimano and SRAM. The SL 5 is also the only 11-speed bike; the rest are 12-speed.

All models come with Bontrager tubeless-ready wheels and Bontrager’s R3 folding-bead, tubeless-ready tires in 32mm.

Claimed weights start at 8.93Kg (19.7 lb.) for the SL 5, with the lightest complete bike coming in at 7.25kg (16 lb.). One interesting note on prices and weights: For the same relative equipment level— Ultegra Di2 versus Force eTap AXS —most Shimano-equipped bikes are less expensive and lighter than the SRAM-equipped bikes. There is a big “but” because all SRAM-equipped Domanes from the SL 7 eTap and up have power meters while the Shimano builds have standard cranks. The other exception is the SL 6 ( Shimano 105 Di2 ) and SL 6 eTap ( SRAM Rival eTap AXS )—the Shimano bike is $600 cheaper but slightly (10 grams) heavier.

As always, the Domane will eventually, though not immediately, find its way into Trek’s Project One customization program for riders who want to pick their parts and paint. Trek also offers the SL ($2,499), SLR, and RSL (both $4,200) framesets for purchase.

Trek Domane Mk.IV—Ride Review

Trek’s Domane has been a favorite of mine since the first generation, but the third generation was flat-out amazing. Comfortable, practical, and fun, it had most of the speed of a race bike without the bullshit that makes race bikes so limited and limiting. It fits big tires! You could run any bar and stem! It could store a burrito in the downtube! And it was fast .

So when Trek told me they were sending me the new, fourth generation, Domane I hoped and prayed that they found a way to make it better without messing up what made it so great. And friends, my hopes and prayers were answered because riding the fourth generation Domane was like reacquainting with a dear old friend, but one who lost a bunch of weight and now goes to therapy. Because this bike is everything the gen-three Domane was, but better.

You can read what I said about the third-generation Domane when I reviewed it and when I wrote it up as our 2020 Bike of the Year and take all of the good stuff and apply it to the new, fourth-generation Domane. But my complaints about it being a little heavy are gone. And with the weight reduction, the gen-four Domane unlocks new performance levels.

The biggest difference is the new bike is quicker, snappier, and just flies. When you hear someone talk about a comfortable road bike, it usually suggests a bike that is squishy and slow feeling. But when you get on a bike that is fast, quick, and communicative but also floats and coddles the rider like a newborn baby, well, that is a special bike. And that is what the new Domane is: Special. A great bike made better. A bike for the modern road rider: Freaking fast, wonderfully comfortable, and oh so practical.

A gear editor for his entire career, Matt’s journey to becoming a leading cycling tech journalist started in 1995, and he’s been at it ever since; likely riding more cycling equipment than anyone on the planet along the way. Previous to his time with Bicycling , Matt worked in bike shops as a service manager, mechanic, and sales person. Based in Durango, Colorado, he enjoys riding and testing any and all kinds of bikes, so you’re just as likely to see him on a road bike dressed in Lycra at a Tuesday night worlds ride as you are to find him dressed in a full face helmet and pads riding a bike park on an enduro bike. He doesn’t race often, but he’s game for anything; having entered road races, criteriums, trials competitions, dual slalom, downhill races, enduros, stage races, short track, time trials, and gran fondos. Next up on his to-do list: a multi day bikepacking trip, and an e-bike race.

Domane SL 5 frame design and size: 

Trek's IsoSpeed system includes front and rear decouplers as well as a rocker cup that allows the seat tube and steerer tube to bend. This contributes to a smooth ride without sacrificing road contact and stability.

The frame's endurance shape is developed to provide the rider a secure, controlled feeling in the saddle .

When it comes to carbon frames, the 500 Series OCLV is a little heavier, which is especially evident on hills. It compensates for this by easily cutting through uneven surfaces. 

With a slightly higher headtube, the endurance geometry used in the Domane range of road bikes is designed for long-distance rides.It aims to strike a compromise between speed and comfort, with a more relaxed seating position than other carbon racing bikes. 

The slanted top tube meets the seat post at an angle that gives the impression of moving virtually continuously into the seat stays.

The downtube is also slightly thicker than typical, with a small curve that produces a pleasing profile view. A true one-of-a-kind carbon frameset is the result of a union of technological perfection and high-quality materials.

The Trek Domane SL 5 2022 is available in eight distinct sizes to accommodate heights ranging from 4'11 to 6'5.

What are the different parts included in Trek Domane SL 5?

Trek's choice of Shimano's 105 groupsets for the 2022 Trek Domane SL 5 was a wise one, and it complements the bike's high-end carbon frame.

Shimano's 11-speed cassette, shifters, chain, hydraulic brakes, front and rear derailleurs, and front and rear derailleurs make up the entire groupset.

The entire set works together to deliver outstanding, fault-free mechanics and smooth operation, allowing you to concentrate on the road ahead.

The Shimano 105 is one of the most durable drive chains on the market, and it has long been a favorite of cyclists all around the world.

The rear gearing and brake lines are run internally through the carbon body of the bike, keeping the frame clean. This not only covers the cables, but also improves the aesthetics and aerodynamics of the entire system.

Unfortunately, the front disc brake cable is not routed through the fork, leaving a tangle of zip ties running down the left fork. It's an unusual pick for a road bike at this price bracket, but it performs just as well, albeit with a less appealing appearance. 

How does it feel to ride Domane SL5? 

The Domane SL5 is perfect for everything. It's not often that we find a decent, comfortable riding posture right away, but the  Trek has a very upright stance that feels like it'll respond to a lot of power.

The sharp seatpost places us directly over the front end, while Shimano's hydraulic brake hoods provide a comfortable resting spot for our hands.

The Domane's 32c tires are a game-changer – it's eye-opening to spend so much time on such wide tires.

Their high-volume, low-pressure setup removes all road grit, leaving us refreshed enough to skip the cafe.

Second, although it may appear to be a minor point, the Domane's handlebar tops are fitted with foam pads before they're covered in tape, which means you can ride for miles with your hands on the bar tops with no vibration traveling up your wrists.

What We Like

• IsoSpeed, which provides smooth rides over obstacles.
• Serves a variety of purposes, from racing to adventures and club rides.
• Comes with a storage compartment.
• Comfortable over long distances

What We Don't Like

• Can be a bit slow on steep hills.
• At this price, it's heavier than most bikes.  

Why should you buy a Trek Domane SL 5 road bike?

The Trek Domane SL 5 is a serious carbon-framed road bike for serious riders who regularly travel great distances.

It would be ideal for semi-professional cyclists and athletes who regularly want to prepare for contests and events.

You'll adore it if you're simply a weekend rider and can afford it.

A bike of this kind, on the other hand, needs to be put through its paces by podium contenders.

It's durable, fast, fairly light, and, most importantly, it's incredibly smooth.

Is Domane SL5 Trek bike value for money? 

• Endurance frame geometry that has been scientifically proven and tested. 
• Shimano components of the highest quality.
• A budget of less than $3,000.

Yes, the Trek Domane SL 5 is unquestionably a piece of gear that fulfills all the boxes and provides outstanding value for money.

In a comparable price range, there are quicker and lighter carbon road bikes, as well as tougher bikes, but none of them strike the right balance quite like the Trek Domane SL5.

This is a bike that will last a long time and will require little maintenance or improvements.

Is Trek Domane a good road bike?

The Domane 3rd generation is one of the top road bikes on the market. The Trek Domane's third generation is not just the best Domane, but also Trek's best-ever road bike. And it's currently one of the greatest road bikes on the market.

Is the Trek Domane SL 6 a good investment?

The Domane SL 6 is a durable bike that is also fun to ride, earning it a spot in this year's Editor's Choice. The Trek Domane SL 6 is the kind of bike with a super-stiff frame and race geometry. 

Is The Domane too heavy?

Yes, it's a heavy bike, but it climbs well, feels robust, and has no power loss. The weight penalty is due to the frame tubes' compliance and aerodynamics. It's not because of the Isospeed of the bike.

The Endnote:

The Trek Domane SL 5 is a road bike that dares to go where no other bike has gone before. This is due to the fact that, unlike some road bikes , its features are made of high-quality materials to ensure efficiency.

The Trek Domane SL 5 is a road bike with a 500 series OCLV carbon frame with IsoSpeed, high-performance gear, Shimano hydraulic disc brakes, and big, comfy tires. A storage box, blender compatible stem, fender mounts, and a micro-adjustable seatmast round out the bike's versatility.

Trek domane sl 5 disc 2017 review.

The Domane range has been around for many years and continues to evolve past the traditional norm for endurance road bikes. It's a hugely popular model for Trek and the 2017 Australian line-up features 15 different models incorporating a Race Shop Limited edition, SLR, SL and S versions, disc and non-disc equipped options, and two aluminium versions.

We tested the Domane SL 5 Disc which features front and rear IsoSpeed technology, huge 32mm tires, flat-mount disc brakes, race-ready Metron Vision wheels and comfortable geometry. Trek has made the bold move of prioritizing wheels over drivetrains, with no better example than the model we tested. Read on to see if that decision is a good one.

• Who’s it for: The everyday rider that wants more performance and doesn't want to make any after-market upgrades.
• What we like: Impressive handling, serious smooth ride, upgraded Vision Metron wheels and 32mm tires.
• What we don’t: Shimano 105 drivetrain at an Ultegra price.

The Domane is positioned as Trek's endurance bike and so adopts the 'endurance fit', which has a longer headtube and shorter reach to put the rider in a more upright position.

A quick look at how the Domane stacks up against the Madone and Emonda and the endurance direction is obvious. For a 58cm frame, the headtube is 0.5cm taller, head tube angle almost 2 degrees slacker, chainstay length over a centimeter longer and the wheelbase 3cm longer, resulting in a taller stack height and reduced reach. All of this aims to put the rider in a more upright position and improve the stability of the bike.

The Domane's 500 Series OCLV Carbon frame is stacked with features that not only compliment the endurance geometry but ensure the bike still has plenty to offer those wanting to ride hard. 'OCLV' carbon is Trek’s patented carbon fibre process and comprises of five 'series'; 700, 600, 500, 400 and 300. The 700 series is reserved for Trek's top-tier creations, while the 600 series features on 'SLR' Domane versions and the 500 series featuring on 'SL' versions.

The foundation of the Domane range is Trek's proprietary 'IsoSpeed' technology which first started with the Domane and has since made it's way onto the aero Madone and even the Procaliber hardtail mountain bike. The idea of this technology is to separate the seattube from the toptube, allowing for greatly increased flex (compliance) in the seat tube, all without sacrificing resistance from twist (flex). For 2017, the Domane sees the IsoSpeed decoupler technology added to the front of the bike, this allows the steerer tube to move independently from the head tube reducing the impact from big bumps in the road. Trek say this new technology 'delivers an additional 10% of front-end compliance over a traditional road bike'.

As important as IsoSpeed is in the rear of the bike, it could be argued that having it in the front is even more important due to the impact felt through your hands, arms, shoulders and how much quicker they will fatigue compared to your legs. In addition, improving handling and compliance at the front should be the priority as it will have the biggest impact on control and comfort of the bike. The introduction of IsoSpeed to the front for 2017 should create a better marriage between the front and rear of the bike compared to previous models with only rear IsoSpeed.

Disc brakes are found on the majority of the Domane range, flat mount Shimano RS505 hydraulic disc brakes the choice for the SL 5. Flat mount calipers are the new standard for road bikes, providing a clean, compact and lightweight option that doesn't sacrifice on power or control when compared to earlier road disc brakes that were borrowed from mountain biking. The disc rotors are 160mm in diameter and provide plenty of stopping power and dissipate heat well to avoid excess build up on long descents.

To accommodate the disc brakes, 12mm thru-axles are used at both wheels. These have a larger diameter than a standard quick release and improve stiffness and steering as a result. It also makes tightening the wheel into position exceptionally easy, doing away with the fiddling and having to know exactly how tight to do the quick release before closing. It also means a flush lever position every time.

The Domane's bottom bracket is using Trek's BB90 system, it's a lightweight option that creates a huge bottom bracket area that allows for large tube shapes and transference of power. Earlier generations of bikes using this bottom bracket system suffered from creaking, however, a new bearing design means this noise should be a thing of the past. This test sample remained perfectly silent during the test period.

There are plenty of other features that come standard with the SL 5: hidden mudguard mounts, internal cable routing and an integrated chain keeper for the front crank. Like other premium Trek road bikes, the SL 5 is DuoTrap S compatible, meaning that the wireless cadence and speed sensor (sold separately) sits neatly tucked within the left chainstay. A Ride Tuned seat mast completes the list of extensive features, Trek uses this in favor of a traditional seat post to best complement its IsoSpeed technology. Trek' reasoning here is that traditional seat posts placed inside the seat tube create a harsh ride by effectively stiffening the seat tube.

With everything that the SL 5 has on offer, it's worthwhile pointing out two features that are exclusive to the Domane SLR range and not featured on the SL; the new rear IsoSpeed with customizable rear compliance and the IsoCore handlebar.

The new IsoSpeed features a twin seat tube design that allows you to customize the rear end stiffness by sliding a spacer that separates the seat tube and integrated seat must. This adjustment allows you to soften or firm up your ride by as much as 9%, allowing you to transition from a stiff race bike to an all-day epic just by shifting a spacer.

The IsoCore handlebar is also exclusive to the SLR range, the intention of the design is to dampen road vibration felt by the rider, while the front IsoSpeed takes care of the bigger hits. You can see an overview of the full 2017 road range from Trek that breaks down each model with specification and price, including the Domane, Madone, Emonda, Silque, Lexa and 1 series.

There's no shortage of R&D that has gone into the Domane frameset, but like any complete bike, it's a sum of all the components and how it rides in the real world that matters most. Let's delve in.

Look to nearly any major brand bike on the market, and you'll see plenty said about the frame and then the level of drivetrain components equipped. In reality, no component makes more of a difference to the ride quality, performance and general quality of a bike then the wheels, and yet, it's a part so often overlooked in a bike purchase. Trek have made the interesting decision to provide upgraded wheelsets on selected models for 2017 for those riders that are looking for added performance without having to make an aftermarket purchase.

In this case, Vision Metron 40 disc LTD wheels are used that instantly catapult the SL 5 into the performance bike category. As the name suggests, the carbon wheels are 40mm deep and feature CNC machined aluminium hubs laced with high-quality aero bladed spokes (24 front / 28 rear).

The 25.5mm width rims have a 23mm minimum tire requirement but come standard on the SL 5 with enormous 32mm Bontrager R2 Hard-Case Lite tires that we found virtually bomb proof. We measured the tire width as 31.7mm on the front and 31.8mm on the rear at 70psi.

A claimed weight of 1,675 grams for the pair puts it up there with the lightest of disc road wheel options on the market, even when comparing to major (and high priced) brands such as Enve, Zipp and Mavic.

Shimano 105 is the drivetrain of choice with a traditional 50/34 compact front crankset, paired with an 11-32 11-speed cassette of the rear. Many people would be surprised with 105 at this price point, where Ultegra is near expected.

Trek have taken the brave approach and clearly focused on ride quality and how well the bike performs for the money, not how it ranks on paper. The first upgrade for most is the wheelset, which Trek have done at the expense of the drivetrain. In this instance, Trek has taken a chance by putting the frame and wheels ahead of the drivetrain, it's a decision we agree with and time will tell if it catches on.

Ride Impressions

I mentioned that Trek has focused on ride quality over how well the bike ranks on paper, and the outcome is a huge success. This bike is the most comfortable I have ever ridden and not only in terms of fit but also in terms of smoothness on the road and the stable and predictable handling it provides.

The 32mm tires are a revelation and not as far removed from a performance point of view as the skinner tyre options as you might think. Prior to riding this bike I would have said running 28mm tires is the largest I would go, but I'm now seriously reconsidering that train of thought. The comfort is unquestionable and performance at high speed wasn't lacking as much as I thought it would. I felt at high speeds, 40kph and beyond, they required more work to keep rolling than my usual 25mm tires but aside from that they were every bit as good. They smoothed out road vibration like nothing I've ridden before and as mentioned, were indestructible. A clear point to make is that most frames and wheelsets aren't built for such large tyres, so 32mm tires aren't likely to fit your current road bike.

As well as being able to accommodate almost cyclocross sized tires, there's no doubt a large portion of the bikes performance was due to the wheelset which performed exceeding well. The larger tire volume and extended Domane geometry made things a little harder to get going but once rolling they carried speed well, weren't adversely affected in strong crosswinds and were responsive in and out of corners. There was no obvious flex during sprint efforts and at below 1,700 grams, they were hardly noticeable during any hill efforts.

While I thought the Domane would be comfortable, I didn't expect it to handle as well as it did. From the outset, I thought dropping it into corners would feel slow and require significant effort to pull it out at speed but this wasn't the case. The handling is rather sharp for an endurance bike and on more than one occasion I came out of the corner thinking I could have gone so much harder. I progressively pushed harder and harder into corners and while the bike as a whole lacked a little agility, it felt balanced, making cornering at speed comfortable and inspired confidence to go harder next time.

It's at this point we need to give some kudos to the team at Trek for providing comprehensive geometry charts on their website. Trek's geometry charts provide the rarely sighted 'trail' and 'offset' figures which give a great insight into the handling of a bike and might explain the impressive results. The Domane comes in at 6cm of trail which is a little greater than the standard for most ride bikes, providing a nice balance of stability and responsiveness. The fork offset is also slightly larger to account for the slacker headtube angle, explaining why, despite being an endurance bike, the Domane provides impressive handling. Check out BikeExchange's guide to geometry charts for more on trail and how it affects bike handling .

The IsoSpeed technology I found less noticeable on this bike than two previous Domane's I've ridden. The use of the larger tires nullifies much of the normal road vibration you feel, as a result, there is less for the IsoSpeed decouplers to do. The only time I was obviously aware of them was when cannoning into a pothole while out of the saddle with the majority of my weight over the front wheel. I felt some movement at the front of the bike but it wasn't what you might expect to feel with a loose headset, instead, it felt rather soft and plush.

I found the IsoSpeed is most noticeable when there is some form of jarring involved, while the tires handle the majority of the lesser road vibration. It's for this reason, I don't feel you're missing too much by not having the 'new' rear IsoSpeed. The additional compliance is hardly required and if it were my own bike, I'd shift that spacer to firm up the ride as much as possible.

The braking performs as expected which is to say flawlessly. Hydraulic braking is smooth, requires little finger effort and is much more consistent than rim braking. My chief complaint with hydraulic disc brakes has always been the larger hoods which I've never been able to find a comfortable position. While I still found this to be the case on the SL 5, the size is gradually reducing as development continues and so was less noticeable than previous hydraulic disc brakes bikes I've ridden.

And so that leaves the drivetrain. As mentioned, most people looking at the price point of this bike would expect Ultegra, possibly even Ultegra Di2 at a stretch, but none of those bikes would come equipped with a quality wheelset like the Vision Metron 40's. And therein lies the conundrum, do you prioritize drivetrain over a wheelset or the other way around? The 105 groupset is considered the workhorse of Shimano's stable; durable, reliable, and the company's first real step into the performance orientated groupset market. The shifting is quick, precise and more than qualified to meet the demands of most of us. If you are looking to upgrade, it also has the ability to swap individual parts with Ultegra and Dura-Ace. And so the cost of upgrading a wheelset versus a groupset is worth consideration when weighing up the value proposition of Trek's - frame > wheelset > groupset - prioritization.

Looking past the name on the drivetrain, the compact crankset paired with the large ratio cassette is the perfect choice for endurance bikes. It provides a huge range for all day riding, and even greater range than standard cyclocross bikes if you fancy taking it on gravel roads. The 50/11 doesn't leave you short on faster road rides either which makes this ratio a great option.

Trek have invested heavily in their R&D department for many years and the fruits of their labour are clearly evident in the Domane frame. Ride quality is paramount and that shone through in my testing. From a buyer point of view, it will be interesting to see what is made of the decision to upgrade the wheelset at the expense of a higher-tier drivetrain. Either way, that shouldn't draw too much attention away from what is a well-executed endurance bike that is capable of so much.

The Trek Domane SL 5 is available in sizes 50, 52, 54, 56, 58 (tested), 60 and 62cm. The sample tested sits on the scales at 8.6kg (without pedals and bottle cages). The RRP is AUD$4,999. Sharing the same frame, there's also the Domane SL 7 (AU$5,699), Domane SL 6 disc (AU$5,699), Domane SL 6 Pro ($5,499) and Domane SL 6 (AU$4,499).

• Exceptional
• Not so good

The Trek Domane SL is a smooth-riding road bike – even an all-road bike – courtesy of IsoSpeed tech both front and rear, which helps it damp down small vibrations and bigger hits. It's not the lightest bike out there, but if ride quality is your main concern, it's a real contender.

First of all, a quick explanation of the bike we're reviewing. The Domane SL frameset arrived at road.cc built up with the new SRAM Rival eTap AXS groupset so that we could review those components too. It's not a standard build, but we've not reviewed the Domane SL before and thought we'd take the opportunity.

> Buy now: Trek Domane SL Disc frameset from Trek for £2200.00

Our 58cm bike, complete with Zipp 303S wheels set up tubeless with WTB Exposure 700 x 30mm tyres, weighs 8.82kg (19.4lb).

Trek does offer the Domane SL 6 eTap with a SRAM Rival eTap AXS groupset for £4,200, although this model is fitted with Bontrager Paradigm Comp 25 wheels.

Okay, on with the show...

IsoSpeed is the headline news here, so let's kick off with what it actually is. You can scroll down a few paragraphs if this is old news for you.

Trek first introduced IsoSpeed in 2012, although it has evolved since then. Rear IsoSpeed came first, decoupling the top of the seat tube from the rest of the frame. The aim is to take the edge off big hits and smooth out smaller vibrations by allowing a small amount of movement at the saddle, thereby keeping you feeling fresher for longer. That's the plan.

How does it do it? Although the seat tube is fixed to the bottom bracket area in the normal way, it isn't moulded to the top tube or seatstays. Instead the tubes are joined by a pivot, allowing the seat tube to flex more than would otherwise be possible.

Front IsoSpeed is a more recent introduction, the idea being greater compliance at the handlebar. Front IsoSpeed comes in the form of a rocker cup at the top of the headset that allows the fork's carbon steerer to flex backwards/forwards, but not from side to side.

Put another way, the upper section of the headset can tilt to take advantage of the inherent flex in the steerer, meaning the stem and handlebar can move slightly in response to rough roads. See? It's simpler than it sounds.

Best of three

The Domane frameset comes in three different flavours. At the entry level there's the Domane AL, with an aluminium frame. This one doesn't feature front or rear IsoSpeed although, a little confusingly, Trek does describe the carbon fork as IsoSpeed on the basis that the legs are designed to absorb vibration. Complete bike prices start at £695, although the cheapest disc brake model is £895.

At the top of the range there's the posh Domane SLR, which comes with front and (adjustable) rear IsoSpeed. Bikes are priced from £6,600.

In the middle you get the Domane SL bikes, which are made from a lower grade of carbon than the SLRs – Trek's 500 Series OCLV, rather than lighter and stiffer 700 Series OCLV. You get both front and rear IsoSpeed, neither of which is adjustable. That means you can't alter the setup according to the terrain but, on the other hand, it's simpler.

> road.cc Frameset of the Year 2020/21

The most accessible 2022 complete SL currently available is the Domane SL 6 eTap mentioned above, although the 2021 Domane SL4, with a mostly Shimano Tiagra groupset, is £2,325.

On the road

So the big question is: how much difference does the IsoSpeed technology make? Don't think that all this tech means the Domane SL feels unlike any other road bike you've ever ridden.

First of all, if you've ridden mountain bikes with loads of travel, IsoSpeed is nothing like that. Not even on the same page. Cast all thoughts of mountain bike suspension from your mind.

When you're riding on level, well-surfaced tarmac, IsoSpeed doesn't feel unusual at all, and even over rough roads it's subtle. In some ways it feels like running wide tyres at fairly low pressures... though in other ways it doesn't feel at all like that (I'll explain in a mo).

You get just a bit of movement to insulate you from what's going on beneath your wheels, and it's more noticeable at the saddle than the handlebar. Crack into a steep-edged pothole at warp speed and you still feel it – just slightly less than you otherwise would.

The main feature, though, isn't the protection from the big hits, it's the smoothing you get from the smaller stuff: little holes, manhole covers, drains, frost damage, badly patched tarmac, kerbs on and off the cycle path... you know, all those things you constantly encounter on a typical ride.

It would come in handy over cobbles too, although chances are you don't have too many of those around your way.

Again, IsoSpeed doesn't eliminate bumps and vibrations from any of this stuff, it just turns it all down a few notches. It's forgiving. The rougher the surface, the bigger the difference IsoSpeed makes. It's great on old, scuffed up tarmac and it's also pretty active on gravel roads although, naturally, the tyres make a big difference here.

> 19 of the best 2021 gravel bikes & adventure road bikes

The Domane takes a maximum size of 700 x 38mm. It isn't designed as a gravel bike – and most people would prefer something a bit wider for full-on gravel – but it's brilliant for short cuts to link up two sections of tarmac, for instance, and if you fancy riding gravel on 38mm tyres, well, you can fill yer boots.

I said above that IsoSpeed can feel like you have large, low pressure tyres – but not entirely. The big difference is that a big tyre can feel squishy and mushy when you put the power down, and that can be annoying on the road.

IsoSpeed doesn't feel like that at all. There's no extra bounce when you're out of the saddle, and no additional lateral movement. The front end tracks and steers well, with no nasty surprises when you bang it hard into a fast, downhill bend.

Speaking of surprises, the frame-integrated storage compartment is a natty addition. You flick a lever on the down tube – where the bottle cage attaches – to release a plate and access the space inside.

The cover has a multi-tool slot on the back, and Trek also offers a tool roll specifically designed to fit. It takes stuff like a CO2 canister and chuck, tyre levers, a spare tube, an emergency Snickers bar... you do carry an emergency Snickers bar, don't you?

Specialized does something similar on its Diverge gravel bikes, and while packing things in these cubbyholes is a bit of an art, it's a really handy addition for emergency essentials.

The Domane SL is relaxed by road bike standards. Trek calls it an endurance fit. I've been riding the 58cm model with a 54.8cm seat tube, a 56.7cm effective top tube, and a 19.5cm head tube. It's a tall bike with a 61.1cm stack height, while the reach is short at 38.0cm. That puts the stack/reach at 1.61 for this size.

Some people are going love how the ride position is more upright than a more speed-orientated bike's, such as Trek's Madone or Emonda, for instance, while others won't be down with it at all. It depends what you're after.

Trek says the current generation Domane is much more aero than previously – courtesy of truncated airfoil tube profiles – but there's only so far you can tweak your position, and that's always going to be more significant when it comes to drag. Personally, I can't see typical Domane SL buyers being over-concerned with aerodynamics, although I guess it all helps.

The brake hoses are exposed only between the ends of the handlebar tape and the front end of the top tube, just behind the stem, where they duck inside via a removable plate. This ensures a clean look and keeps them out of the wind.

As mentioned, the bike I've been riding has a SRAM Rival eTap AXS groupset so there are no shift cables/wires to worry about anyway, but if there were any, this is the only place you'll see those too.

Other features you need to know about include the adjustable seat mast that's particular to the Domane – held by an internal clamp accessed via a slot in the extended seatpost – and the T47 bottom bracket. Hooray for threaded BBs!

Mudguards? You can fit 'em easily enough. You get threaded holes on the fork legs (filled with itty bitty grub screws when not required) and another beneath the fork crown. You get more at the bottom of the seatstays, and fairly discreet mountings for a chainstay/mudguard bridge towards the top.

The only real downside to the Domane SL is that it's not particularly light. Trek claims a frame weight of 1,365g while, as mentioned, this complete bike came in at 8.82kg (19.4lb). Okay, the SRAM Rival eTap AXS isn't a lightweight groupset, but then a few hundred grams on the frame doesn't affect the ride as much as some people would have you believe.

The money bit

There aren't many road bikes designed to smooth the ride quite like the Domane. The most obvious rival is the Specialized Roubaix, which has Future Shock front suspension – a spring in a cartridge above the head tube that allows movement of the stem and handlebar.

The top-end Specialized S-Works Roubaix Team frameset is £3,700, but comparing prices with the second-tier Domane SL is unfair. Trek's flagship Domane SLR frameset is £3,500, so there's not a great deal in it.

The Domane SL keeps you comfortable thanks to relaxed geometry, front and rear IsoSpeed tech, and the ability to take tyres up to a whopping (by road bike standards) 38mm wide. It's as versatile as it is smooth, and if you want to mix up the surfaces you ride on while retaining plenty of speed, the Domane SL is a strong option.

Make and model: Trek Domane SL Disc frameset

Size tested: 58cm

Tell us what the frameset is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about the bike?

Trek says, "The lightweight Domane SL Disc Frame Set is built with 500 Series OCLV Carbon and includes road-smoothing Front and Rear IsoSpeed, so you can stay stronger for longer. This carbon endurance road frame is designed for flat-mount disc brakes, has a built-in storage compartment, and includes a headset and a Domane Disc full carbon fork."

Trek tells you everything you need to know about IsoSpeed over here: www.trekbikes.com/gb/en_GB/inside_trek/isospeed

Trek says, "IsoSpeed challenges the traditional design of a bicycle frame. Devoid of the more favoured approaches to the compliance quandary (such as suspension systems, elastomers or a vibration damper), IsoSpeed maintains the diamond-shaped frameset geometry but 'decouples" the seat tube from the top tube, allowing the seat tube to flex with the forces of the road. The result is a bike that moves with the road while maintaining the feel and efficiency of the traditional race bike design.

"One of the consistent pieces of feedback from riders that have enjoyed rear IsoSpeed was that even though they could plough unfazed through rougher roads than ever before, they could still feel the road shock through their arms from the front wheel. Our solution was to take everything that works from IsoSpeed and move it up the bike. The same technology that provides great compliance at the saddle now delivers compliance at the front end. Front IsoSpeed, located at the top of the headset, is captured in a rocker cup similar to rear IsoSpeed. This allows the steerer tube to flex, providing additional compliance at the front of the bike. The rocker cup of the upper steerer has zero lateral movement, allowing the bike to steer and handle with precision."

State the frame and fork material and method of construction

Frame: 500 Series OCLV Carbon, front and rear IsoSpeed, internal storage, tapered head tube, internal cable routing, 3S chain keeper, DuoTrap S-compatible, mudguard mounts, flat-mount disc, 142x12 mm thru-axle

Fork: Domane SL carbon, tapered carbon steerer, internal brake routing, mudguard mounts, flat-mount disc, 12x100 mm thru axle

Tell us about the build quality and finish of the frame and fork?

It's built to a very high standard.

Tell us about the geometry of the frame and fork?

Trek calls it an 'endurance fit,' and it's pretty relaxed by road bike standards. I've been riding the 58cm model with a 54.8cm seat tube, a 56.7cm effective top tube, and a 19.5cm head tube. It's a tall bike with a 61.1cm stack height, while the reach is short at 38.0cm. That puts the stack/reach at 1.61 for this size.

How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?

It's taller and shorter than an equivalent Madone or Emonda, say, putting you in a considerably more upright position.

Riding the bike

Was the bike comfortable to ride? Tell us how you felt about the ride quality.

Yeah, this is what the Domane is all about. It feels very comfortable courtesy of the front and rear IsoSpeed, and the ability to fit tyres up to 38mm wide. The relaxed geometry takes the strain off your back and neck, too.

Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?

The IsoSpeed tech allows up/down movement, but doesn't affect the lateral stiffness of the bike.

How did the bike transfer power? Did it feel efficient?

It feels pretty efficient, yes.

Was there any toe-clip overlap with the front wheel? If so was it a problem?

My shoe just missed 30mm tyres; there's a small amount of overlap with larger tyres.

How would you describe the steering? Was it lively neutral or unresponsive? It's pretty neutral

Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?

This is a bike that's more about stability and ride quality than sharp handling.

This isn't especially focused on accelerating or sprinting.

Your summary

How does the price compare to that of similar products in the market, including ones recently tested on road.cc?

The most obvious comparison is with the Specialized Roubaix, which has Future Shock front suspension – a spring in a cartridge above the head tube that allows movement of the stem and handlebar.

Did you enjoy riding the bike? Yes

Would you consider buying the bike? If ride quality was my highest priority, definitely

Would you recommend the bike to a friend? Yes

Use this box to explain your overall score

The performance is very good. Although the price is higher than many other road bikes, it's very good when you consider the tech that features here.

£2,325 for a Tiagra equipped bike is having a laugh......

It's horses for courses. I had an SL5 disc with Vison 40mm carbon rims and 105 as standard a few years ago and tbh, it's a nice enough bike but I found it dull as dishwater...as did a couple of people I know who bought better and lesser versions of the same model year.

The person I sold mine to loved it however and boasted of smashing PB's. If you can I'd advise a test ride

How upright are we talking? Can you still stretch yourself out riding the drops?

More than likely, provided you get the correct size.

The only way to answer that is to sit on one. A decent substitute is to compare the geometry to a model you're familiar with.

It's certainly taller, but not that much shorter than an Emonda say.

I have both and they're setup within a couple of mm of each other

Review: Trek Domane SL Road Bike – Quick, Comfortable, & Easy to Recommend

It's easy to see why the domane all-road bike is so popular, even if it rubbed me the wrong way at times..

• Comfortable fit geometry
• Seriously smooth ride
• Surprisingly snappy handling
• Useful downtube storage
• Price is higher than most
• Not especially light

There’s a decent likelihood that if you see someone riding a Trek road bike from the last decade or so, it was the brand’s Domane model. The ubiquity stems largely from its fit geometry, which has historically been very welcoming to riders of all abilities. Furthermore, the Domane’s unique IsoSpeed decoupling suspension system promised levels of comfort that other road bikes couldn’t quite match.

The IsoSpeed suspension system lives on in this latest Trek Domane SL road bike, but the rest of the package might be the biggest change we’ve seen with the Domane yet. There’s aero tube shaping, a lighter frame, and an added sense of performance that wasn’t quite there with previous Domane SL bikes.

We spent 1,000 miles on the Trek Domane to find out just how good the Domane is, whether that pursuit for speed has removed any form of comfort, and the potential downsides of living with a bike like the Trek Domane SL.

Quick hits: Seven things to know about the Trek Domane SL

• The Trek Domane lineup features three main framesets: the top-tier Domane SLR , the aluminum Domane AL , and this mid-range Domane SL carbon road bike. The Domane RSL is available as a frameset.
• Every Domane features fully internal cable routing through the headset, though the stem functions similarly to a traditional stem.
• The latest Domane SL and SLR bring a new internal storage compartment for a tube, tools, and an included neoprene storage sleeve.
• Max tire clearance is a quoted 700c x 38 mm.
• A new Domane SL frame weighs a quoted 1391 grams, 300 grams lighter than the previous Domane SL.
• Domane SL features a rear IsoSpeed decoupler to improve seated comfort, though it is no longer adjustable.
• Domane SL is available in seven sizes to fit riders between 4’11” to 6’5”.

Frame details

The Trek Domane is known for being an approachable road bike. Much of that comes down to handling geometry that values straight-line stability over race bike agility. Its fit geometry is more accommodating of a non-competitive cyclist than other bikes in its category.

The IsoSpeed seat tube flex system isolates riders from road vibration in a way few other bikes do. And while there are a number of changes to the latest Domane SL, most of those characteristics carry on.

IsoSpeed is a critical component of any recent Trek Domane road bike. Previous generations really went for it, offering not only adjustable rear IsoSpeed systems but even a front-end system to balance comfort between the two ends. This latest system essentially overhauls IsoSpeed, largely for the better.

Most notable is that this latest iteration is said to offer as much flex as the softest setting in previous IsoSpeed systems while using a simpler D-shaped seat post. Previous Iterations of IsoSpeed used a carbon seat mast to offer the flex they wanted, but it was far more fiddly to use than this simpler system.

The front IsoSpeed system is gone, as the swap from 28 mm to 32 mm is said to be plenty comfortable. The fact that this system has far fewer moving parts and wear items should result in fewer creaks and durability issues compared to previous-generation systems. Trek says the system needs no servicing for the lifetime of the bicycle, and I never had issues with it in my time with the bike.

The Domane SL isn’t a particularly light bike. Some of that comes from the addition of a downtube storage hatch located under the bottle cage mount. Inside is a neoprene mini tool sleeve as well as plenty of space to add more snacks and perhaps a vest should you need to. It’s a genuinely useful storage area, with a sturdy latch and hatch system.

Trek’s Domane continues with internal cable routing, though this system is among the more refined systems I’ve seen and worked with. Cables are external at the bars until they’re routed under the stem, leaving some slack to play with stem height. And while the spacer profiling limits what types of stems you can swap with, doing the swap itself is an easy enough process that almost anyone can manage.

The internal routing system itself is one of the better setups I’ve seen. A guide at the inside of the downtube includes a holster for the Shimano Di2 battery, with guides for brake hoses and cable housing easily accessible from the downtube storage hatch. It’s easy to work on, all things considered.

Tire clearance has always been a strong suit of the Domane, and that hasn’t changed. Max clearance is a quoted 700c x 38 mm tire. I was able to fit a 40 mm (42 mm width as measured) Pirelli Cinturato Gravel H tire front and rear without rubbing. That clearance makes light gravel and dirt road riding doable, but it would be problematic on a muddy or chunky ride.

Other bits of note include the use of a T47 threaded bottom bracket, the addition of top tube bag mounts, and hidden fender mounts. The frame gets its own integrated chain keeper, a nice touch that indicates the general user-friendliness of the bike.

The build brought in for review was the Trek Domane SL 6 Gen 4. The highlight of the bike is the Shimano 105 Di2 drivetrain. The Bontrager Paradigm 25 wheels feature tubeless-ready alloy rims with a wide 25 mm internal width. The 32 mm Bontrager R3 Hard-Case tires, Bontrager Verse Short saddle, and Bontrager alloy handlebars complete the build.

A size 56 cm bike has a quoted weight of 8.62 kg (19 pounds. My 50 cm build weighed in at 8.5 kg (18.73 pounds) without pedals and accessories but with tubes in the tires.

The Domane has a reputation for being an upright road bike with handling that might be best described as stable. While the bike is stable, the geometry is far more agile than you’d expect.

Trail figures are around 59 to 61 cm across just about every size but the 44 cm bike. Handling geometry is quick enough for most people, though the low 75 to 80 mm bottom bracket drop and 420 mm chainstays add some straight-line stability back.

Fit geometry and rider positioning can be considered as upright, with a taller stack height and short reach dimensions. These numbers are taller and shorter respectively than even most all-road bikes, but I’d argue the numbers are realistic for most riders. Those looking for a more than 6 cm of saddle to bar drop (particularly on small sizes) will be better suited to something like their Emonda or Madone road bikes.

Standover heights across most sizes are about as low as I’ve seen on an endurance road bike, which is helpful for the height-challenged among us.

Riding the Trek Domane SL

The value of the Domane doesn’t necessarily come from its cost or its tech-forward features, but rather in its promise of being a comfortable, approachable road bike. That isn’t lost here: the Domane is one of the most approachable road bikes you’ll find and an easy recommendation for anyone looking for a road bike.

The Domane rides as smoothly as it always has on smooth tarmac and chip-seal. The way the bike goes about smoothing out those small, constant vibrations is impressive. Roads I remember as feeling particularly jostling felt far smoother, both at the saddle and at the bars.

Much of that smoothness comes down to the 32 mm wide tires, which are wider than you’d find on most other all-road and endurance bikes out of the box. That said, narrower tires didn’t detract much from the bike’s smoothness over chip seal-type surfaces. Stay seated, and let the rear end of the bike do its job.

As much as I liked the Domane SL, the bike didn’t feel as eager as I would have hoped. Steeper climbs and even pedaling from a stop indicated that much of that came down to rotational weight. But with a set of carbon wheels and a good set of 30 mm tires, the Domane really woke up.

A set of Hunt Aerodynamicst 44 wheels and 30 mm Vittoria Corsa Pro Control tires gave the bike the feel of a bike far more willing to not only get up to speed but maintain it as well. If you’re itching to make an upgrade, rest assured that a decent set of carbon wheels – like their own Bontrager Aeolus Pro 37V – wake the bike up dramatically.

The stock Bontrager wheels are serviceable otherwise. They’re on the heavy side at over 1950 grams with tubeless tape and valves, but spoke tension and overall build felt like they were going to last. As serviceable as they are, however, it helps to know that you a swap to mid-range Hunt carbon wheels cut over 1 pound (520 grams) from the weight of the bike.

The Bontrager R3 Hard-Case Lite tires are grippy and seem to be long-lasting. That said, I felt the tires felt stiff and slow. A simple tire upgrade alone makes the bike feel considerably more eager.

I found little fault in the rest of the build kit. Shimano 105 Di2 works phenomenally, with quick shifts and gearing plenty low for fondos. The Bontrager Verse Short saddle is wonderfully supportive for how soft the saddle feels. The Bontrager short-reach handlebar choice deserves some praise; its 38 cm width in a 50 cm frame is smaller than most product planners choose but the right size for smaller folks.

The Domane SL rubbed me the wrong way

There was one notable fault I found with the bike, however: the IsoSpeed cover rubbed the inside of my legs on a 125 mile (200 km) road ride enough to create a rash.

A bit about me: I am fairly small at 5 foot, 6 inches and 130 pounds (59 kg) in kit. My legs aren’t particularly big, but they aren’t as lean as they could be either. I’ve received a professional fit and matched that fit onto the Domane SL to ensure my cleats (and feet) are roughly where they should be.

Here’s what the lead engineer of the Domane SL had to say:

“The Domane SL maintains the same thigh clearance as used on other road bikes. How far the max width carries up the seat tube can very slightly between models and this variation may be what you are experiencing compared to another Trek road bike. If it is an issue you could try going to a smaller size which moves his saddle up compared to the frame.”

The Domane SL top tube is wide, particularly as it approaches the seat tube junction. It’s wider at the seat tube junction than any other road bike I’ve ridden this year, though I don’t usually have problems with wide top tubes. The design weakness comes is the location of the IsoSpeed cover; the plastic cover seemed placed perfectly to rub the inside of my legs just above my knee raw.

Could I have sized down? Not really. I was on a 50 cm frame with the seat post extended to its minimum insertion point. Any smaller and I would need a drastically longer stem that would alter the handling Trek intended the Domane to have from the factory. Ultimately, some helicopter tape along the seam stopped the rub, but should I have to do that with a new frame?

Like as with any other bike, give the Domane a test ride before you buy it, particularly if you’re smaller or have bigger thighs like I do. I suspect I am in a very, very small majority of folks to experience this. Considering how many Trek bike dealers there are in the world, it should be easy enough to take the bike for a spin.

The Trek Domane SL 6 vs the competition

Call it an endurance road bike or an all-road bike, this segment is one of the most competitive segments you’ll find. The three endurance road bikes I’ve ridden in recent memory are the BMC Roadmachine , Canyon Endurace , and Cannondale Synapse . The Domane offers the most upright fit geometry, but all are fairly comfortable to ride for the average cyclist.

Surprisingly, I found the Domane to have the quickest steering of the bunch. Despite that, it feels about as stable in a straight line as the other bikes. Add in the IsoSpeed system that seemed to smooth out chipseal as well if not better than the other bikes too as well as its internal frame storage and the Domane starts to stand out.

The Endurace edges the other three bikes out on value for money, offering Shimano Ultegra Di2 and nicer tires at a lower price point. However, I wouldn’t be surprised if you were able to find the Trek, BMC, or Cannondale on sale at a local bike shop, in which case you start to find good value for the money.

I would also take a close look at the Trek Domane AL , one of the most impressive bikes I’ve ridden in recent memory. It might lack the ultimate polish and ride smoothness of the carbon bikes, but the handling, rider fit, and wide 32 mm tires are still there. It’s a fantastic bike.

Choose the Domane SL if you’re looking for about as smooth a ride as you’ll find, want internal frame storage, and need the ultimate warranty support that comes from seemingly having a Trek dealer on every block.

Long story short, I came away surprised by the bike. The latest generation Domane SL is every bit as smooth as you’d expect a Domane to be, and an approachable bike too. There’s a reason why it’s a go-to recommendation for most cyclists: the Domane reliably ticks every box for most road cyclists.

You pay for the privilege of riding the Domane, but considering how smooth the bike is over tarmac, I’m sure a vast majority of riders will be more than happy with it. The clearance for gravel bike tires, the internal frame storage, and the general refinement of the bike are all icing on what is a truly versatile all-road bike.

Just make sure you ride it so it doesn’t rub you the wrong way.

The Trek Domane SL 5 Gen 4 features a lightweight 500 Series OCLV carbon fiber frame and rear IsoSpeed, which absorbs road vibrations and ensures a comfortable ride. Its integrated bike seat enhances both its appearance and riding feel.

Now, let’s dive into the riding experience, key features, components, specifications, and other versions of the Trek Domane SL 5 Gen 4. In the latter part of this article, we will also compare it with several other top bicycle models. If you’re interested in more bike reviews, stay tuned.

Riding Experience

The Trek Domane SL 5 Gen 4 offers a lightweight and responsive riding experience, with high-performance components and generous 38c tire clearance. This allows me to tackle almost any road, from smooth asphalt to gravel paths.

For this review, I took the Trek Domane SL 5 Gen 4 on a spontaneous ride through the countryside, starting with mostly flat and open roads. As I progressed, I encountered some unpaved gravel roads, providing an opportunity to test the bike’s capabilities.

Trek Domane SL 5 Gen 4 On the Road

As soon as I hopped on the Trek Domane SL 5 Gen 4, I was impressed by its responsive pedaling feedback. The lightweight and robust 500 Series OCLV carbon fiber frame contributed to the bike’s agility and speed. The integrated design of the entire bike frame made it even more aerodynamic, allowing me to pick up speed.

When I desired a faster pace, the Shimano 105 2×11 drivetrain provided silky-smooth shifting and efficient power transfer. By increasing my pedaling cadence, I effortlessly achieved higher speeds. The bike’s excellent geometry also made it easier to maintain a forward-leaning riding posture while climbing, maximizing power output. Combined with the ample gear options, I adjusted the rear derailleur to a larger freewheel, making pedaling feel light and energy-efficient when tackling uphill sections.

After conquering the climbs, and facing a long downhill stretch, I took advantage of inertia and barely needed to pedal to maintain high speeds. The Shimano 105 hydraulic disc brakes, on the other hand, offered strong and reliable stopping power. A gentle squeeze was all it took to apply ample braking force, ensuring safety and stability during downhill rides.

Gravel Riding

The Trek Domane SL 5 Gen 4 also proved to be a capable gravel bike. Towards the end of my ride, I encountered a stretch of gravel road.

Thanks to the carbon fiber frame, front fork, and rear IsoSpeed design, the bike absorbed road vibrations, providing a smoother and more comfortable ride.

The 700c wheels demonstrated excellent rolling capability, allowing me to effortlessly navigate over minor gravel obstacles. The 700x32c tires, in my opinion, were sufficient for handling these gravel sections. However, if you still have concerns, the Trek Domane SL 5 Gen 4 supports a 38c tire clearance, which should alleviate any worries.

Specifications

The Trek Domane SL 5 Gen 4 offers a smooth, aerodynamic, and comfortable ride. Its lightweight 500 Series OCLV carbon fiber frame, combined with the rear IsoSpeed design, eliminates road vibrations and reduces rider fatigue.

The bike is available in 7 frame sizes, catering to riders with heights ranging from 4’11” to 6’2″. It covers a wide range of rider heights, making it suitable for a diverse audience.

It features the reliable Shimano 105 drivetrain, known for its smooth shifting. Additionally, the Shimano 105 hydraulic disc brakes provide all-weather stopping power, remaining dependable even in adverse conditions.

Finally, the down tube houses a convenient internal storage space for essential riding items, making it suitable for long-distance rides. Additionally, the generous 38c tire clearance allows you to ride on nearly any road surface, from asphalt to gravel.

What do we like about it?

• IsoSpeed technology and up to 38mm tire clearance absorb road fatigue and provide a smoother, more comfortable riding experience.
• Wireless 2×11 Shimano 105 drivetrain, offering excellent reliability for entry-level professional components.
• It is versatile and smooth, suitable for long rides on open roads, gravel riding, and racing.
• The internal storage compartment in the down tube offers a multifunctional space for riders to store tools and cycling gear.
• The new frame design reduces weight and offers higher riding speeds with an updated Kammtail tube shape.
• The stable endurance geometry ensures comfort on long rides while maintaining the speed of a racing bike.

What don’t we like about it?

• The limited adjustability range of the seat post.
• What is the rider weight limit for this bike?

The rider weight limit is 275 pounds, which is the standard limit for other Trek road bikes.

• Can this bike accommodate gravel tires?

It can accommodate 38mm gravel tires.

• How do I choose the right size?

These sizes are general guidelines, and the best way to find your perfect size may vary from person to person. The easiest way to determine your size is to go for a test ride.
