Feb 2023 · James Huang
Trek’s latest iteration of its Domane all-roader packs more performance than ever, but there are also some big missteps that give me pause.
Superb rear-end ride quality, stiff and efficient-feeling under power, excellent handling, sleek aesthetics, competitively weight.
Ride quality still a little imbalanced, creaky IsoSpeed/seatpost area, exposed headset bearing, internal housing rub, disappointing tires.

Neat, low-maintenance integrated cockpit
Oh boy is it pricey
I would hope for top-spec tyres at this price

The Domane is a tremendously smooth bike thanks to Trek’s IsoSpeed rear damping system and high volume, 32mm tubeless tyres
The new Domane is everything great about the old bike, plus lighter and quicker.
Trek Domane SL 6 review
The versatile and comfortable Trek Domane SL 6 put to the test
- Sign up to our newsletter Newsletter
The Trek Domane SL 6 is a do-it-all bike that offers amazing comfort over long distances. It may not be the most sprightly bike out there, but it's a versatile machine that won't let you down, and comes with a great spec at a competitive price.
Slightly sluggish on steep hills
You can trust Cycling Weekly. Our team of experts put in hard miles testing cycling tech and will always share honest, unbiased advice to help you choose. Find out more about how we test.
The Trek Domane SL 6 enters Editor's Choice 2019 thanks to its superb versatility and great spec that provides comfort over any endurance ride. I've done century rides, touring rides and fast paced group rides with the Domane SL 6 never letting me down. A reliable bike that is a pleasure to ride, the Domane SL 6 is well worth it's place in this year's Editor's Choice.
The Trek Domane SL 6 is a very different kind of bike to the super-stiff frame and racey geometry I'd usually choose to ride. It's endurance setup and all-round capabilities won me over though and I was left hugely impressed after putting in a lot of miles on it.

The Domane is Trek's endurance offering, with its ride-smoothing IsoSpeed frame technology the unique selling point over other brands. The SL 6 is the mid-range offering, retailing at £3,200 with the most expensive version (the SLR 9) retailing at over £9,500.
The front and rear IsoSpeed is certainly the most noticeable thing when first riding the bike. Coming from a super-stiff frame, it's instantly noticeable how forgiving this bike is over rough roads and was perfect for the varying quality of British lanes in the early winter.
The IsoSpeed decouplers sit at the rear of the top tube and in the head tube, but unlike the higher end models in the Domane range you aren't able to adjust the rear IsoSpeed for more stiffness or more comfort on the SL 6. It would be a nice option to be able to adjust the bike to the style of riding your doing, but the comfort offered here on the fixed setting felt great nonetheless.
One concern ahead of riding the SL 6 was whether the dampening technology would compromise any power transfer or how fast the bike would feel. The SL 6 carbon fibre frame has some quite bulky tubes, and was responsive to seated and sprint efforts along the flats and draggy inclines. The aerodynamic shaping of the tubing also added to that feel.
Really steep climbs with efforts out of the saddle was the bike's weakest point however. It didn't feel sprightly - particularly in comparison to the Specialized Tarmac and Giant TCR I'd just ridden - and wasn't inspiring any attacking on the harsh ramps. But the Domane isn't really designed for that, though it features a wide range of gearing (50/34 at the front with 11-34 rear) that did allow me to get over anything with no trouble.
The best thing about this bike is definitely it's versatility. I used it for short commutes, long weekend rides, some short fast rides and even for multi-day touring. Trek has helped this feeling of versatility by building in neat features like the down tube storage compartment for your tubes, tyre levers and CO2 canisters, as well as built in mounts front and rear for Bontrager lights; all great touches that helped on those long rides and while touring.
Wheels can often be a mixed bag at this sort of price range, but I was impressed by the Bontrager Paradigm Comp 25 wheels provided on the Domane SL 6. With a rim width of 25mm, the wheels came shod with 32mm tubeless Bontrager R2 Hard-Case Lite tyres that I thought rolled really well and felt plenty fast considering their size and shallow rim depth. Moreover, the wheels felt stable and robust, adding to the comfort factor for endurance riding. I had no punctures or issues with the wheels at all over hundreds of miles of testing. The frame also allows you to add up to 38mm tyres if you want to as well as mud guards, perfect for winter or taking the bike over cobbles or light gravel paths.
The SL 6 comes with mechanical Shimano Ultegra R8000 which as usual performed brilliantly with crisp and reliable shifting. The bike uses flat-mount Ultegra hydraulic disc brakes which really added to the feel on long or technical descents.
In terms of value I think the Domane SL 6 is in the expected range for what its offering, coming in £200 cheaper than the comparable Specialized Roubaix Comp for example. Although this isn't the kind of bike I would usually ride, I was genuinely taken with what the SL 6 offered with it's all-round capabilities.

Trek’s long-running endurance road bike , the Domane, has an impressive history of wins, including both of the most famous cobbled Classics, Paris-Roubaix and the Tour of Flanders.
Over the years, the Domane has evolved from a soft-tail road bike to a front and rear IsoSpeed suspension-equipped bike with aerodynamic shaping, inspired by the Wisconsin-based brand’s aero road platform, the Madone.
The Domane chassis, along with its suspension, also has a class-leading tyre clearance of 38mm.
All of these elements combine to create a machine that should prove the Domane capable of meeting anyone’s endurance-bike needs, and much more beyond. It’s fully deserving of its place in the endurance category of our 2022 Bike of the Year Awards
The original Domane was based around a simple idea of separating the seatstays and top tube from the seat tube, to allow the seat tube to act like a long seatpost moving fore and aft and taking the sting out of rough roads.
This was achieved via Trek’s IsoSpeed decoupler; the design constrained the seat tube laterally, but it was joined via a ‘pin’ joint that rotated around a slick bush as the seat tube flexed.
The Domane has evolved with a front IsoSpeed system that works in a very similar way. The traditional headset is replaced with a rocker cup located at the top of the headset that locks in the steerer tube laterally and, like the rear, allows the steerer to flex fore and aft, smoothing out the road.
The Domane frame routes the brake hose under the bar and stem, and around to the rear of the head tube (not dissimilar to how Cervélo routes its S-Series bikes). It’s an obvious nod to aero, though Trek hasn’t gone as far as the full integration seen on Cervélo’s Caledonia .
I like that the frame boasts some great practical features, including proper mudguard mounts (Trek has dedicated Bontrager mudguards for the Domane) and top-tube mounts for bento-box style storage.
It even has a storage chamber hidden underneath the down tube bottle bosses that’s large enough to store a spare tube, CO2 cartridge and multi-tool , plus it comes with a custom-sized tool wrap to stop any rattles.
Trek Domane SL6 eTap specifications
The SL6 might ‘only’ be available constructed from Trek’s OCLV 500 series carbon, compared to the 700 series found on the much pricier SLR models, but despite weighing a few extra grams it’s still very much a premium carbon chassis with some clever tech built in.
The drivetrain comes courtesy of SRAM’s very impressive and affordable (considering it’s electronic) groupset, Rival eTap AXS . Its shifting is a match for SRAM’s more expensive wireless offerings, and it shares the same tunability and connectivity through the brilliant, and free, AXS app.
The 46/33, 10-36 gearing combination is pitched perfectly for a bike such as this. The 46/10 bottom gear has all the speed potential I want when descending or pushing hard on the flat.
At the other end, the 33/36 offers such a light, easy-to-spin gear that I found myself actively looking for steep climbs on my test rides just to see how achievable the Domane makes climbing.
Elsewhere, as you’d expect on a Trek bike, parts are all from Bontrager (Trek’s component partner brand).
The wheels are Bontrager’s Paradigm 25s. As the name suggests, these have a shallow depth rim that’s impressively wide at 25mm (internal), and they’re shod with Bontrager’s R3 tyres in a generous 32mm width.
With the Domane, Trek was one of the first brands to properly explore wide rims and tyres on an endurance bike. It’s certainly set a trend – just look at the specification of Cannondale’s Synapse and BMC’s Roadmachine for evidence.
The cockpit combines a simple alloy Bontrager stem (compatible with the range of Blender out-front accessory mounts) and IsoZone VR-SF handlebar.
The bar is designed to work with Bontrager’s gel pad and tape combo and is, quite frankly, brilliant.
Oversized top sections fit perfectly in the hand, while the compact drop is so well shaped that, even if you’re the most hood-hanging of riders, you’ll find yourself enjoying the aero advantage of staying down in the drops comfortably.
Out back, Trek has a unique approach to the seatpost on the Domane, because the IsoSpeed system relies on the seat tube being able to flex unhampered.
Rather than using a standard post, the Domane has a shortened mast that inserts into the extended seat tube. This locks into place through an internal expanding clamp, accessed through a slot in the seat tube.
It works well, but make sure the bike is set up for you in store, because the minimal adjustment through the mast means you need to make sure you get the correct-length mast. It’s topped with Bontrager’s rather traditional-shaped and very amply padded Verse saddle.
Trek Domane SL6 eTap geometry
My 56cm test bike has a 591mm stack, combined with a short 377mm reach. It makes for a fairly relaxed ride position compared to the Cannondale Synapse, and especially the Cervélo Caledonia.
I found myself altering the saddle position, sliding it back to the limit on its rails to extend the reach and allow myself to get a bit lower.
The 71.9-degree head angle is more relaxed than most endurance bikes, while the 73.3-degree seat angle is steeper. Trek has kept the wheelbase short, however, at just 1,008mm.
Trek Domane SL6 eTap ride impressions
The Domane is one of the smoothest road-going bikes ever made, and certainly one of the best-rolling bikes I’ve tested. That’s quite the bold statement, I know, but the way in which the Domane simply glides over poor surfaces is truly a wonder.
The Domane’s origins as a cobble-busting racer set the standard for its compliance, but its evolution makes it very much an endurance bike of today.
Not many racers would opt for a 32mm-wide tyre, but I’m sold; the R3s roll beautifully.
Yes, they may carry a bit more weight than a 26 or 28mm race tyre, and they’re wrapped around some pretty middleweight wheels in the Paradigm 25s (1,775g a pair). That may make some of you turn your nose up but, on the road, I didn’t notice any excess weight.
The Domane is a mean companion on ascents. Despite weighing close to 9.5kg, it simply wafts over rough tarmac, and the light end of the Rival gear range makes for comfortable climbing.
It breezes uphill if you’re sitting on the saddle and holding the tops, with their comfortable oversized diameter and wonderfully plush cushioning tape.
If you want to get out of the saddle up in the hoods and punch it to the summit, you’ll find a bike that responds in kind.
Descending is almost as impressive – the slightly relaxed head angle, combined with the compliance in the chassis, makes for a bike that’s so very assured going downhill at speed.
I found myself carving into corners, looking for the best line and ignoring imperfections in the road surface, safe in the knowledge that whatever I threw at the Domane, it simply smothered the bumps, swallowed the ruts and kept on tracking straight.
The Domane’s brilliant handling on rough roads, along with its generous 38mm tyre clearance, opens up the world of light gravel. Just like Cannondale’s new Synapse and the wonderfully different BMC Roadmachine X, the Domane is off-road capable – and it pre-dates both of those designs.
As part of my test riding, I took the Domane on unmetalled military roads and wide byways, and it coped admirably, swallowing ruts and lumps with ease.
As with the Synapse and Roadmachine, I wouldn’t head for technical singletrack on it, but excursions on Welsh forest fireroads, the rail trails of the Peaks, gravel roads of north Yorkshire, my home military roads of Salisbury Plain and New Forest tracks are easily within the Domane’s capability.
Trek Domane SL6 eTap bottom line
The Domane SL6 set the standard for the new breed of versatile endurance bikes. It may have been born from the needs of a few elite athletes in a few elite races, but it’s a bike that could easily be one of the most versatile on sale today.
The groupset is excellent: easy to use, packed with features beyond stopping and shifting gears, and very reliable. Although you can find it on much cheaper bikes, all of the components do their job well, yet none are particularly show-stopping.
Comfort is impeccable, even though for me the squishy padded saddle is a bit of overkill (though not uncomfortable).
The Domane, with the complexity in its chassis design, carries a bit more weight than its rivals, but none of them can match its smoothness.
Endurance Bike of the Year 2022 | How we tested
The best endurance road bikes combine a comfortable ride position with heaps of versatility – including features such as mudguard or pannier rack mounts – and speed, to create a useful platform that will fare well no matter the ride.
Testing for our 2022 Endurance Bike of the Year category began with a high-tempo 2.5-hour ride to get an early impression of a bike’s ride quality and to carry out any adjustments.
For the meat of this year’s testing, each bike was taken on the same 82-mile/132km loop through rural Wiltshire.
After this, we rode the bikes back-to-back, coming to a decision on the best by comparing how well each handled across a variety of terrain and, in a competitive market, how its spec compares with the other bikes on test.
Our 2022 Endurance Bike of the Year contenders are:
- BMC Roadmachine X
- Bombtrack Audax
- Cannondale Synapse Carbon LTD RLE (category winner)
- Cervélo Caledonia Ultegra Di2
- Trek Domane SL 6 eTap
Thanks to our sponsors HUUB , Lazer , 100% and Garmin for their support in making Bike of the Year happen.

"Trek’s best road bike gets faster, lighter, quicker, and better"
"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."
"The original racer, yet massively versatile"
"The ride is simply sublime. Its balance between smooth, vibration-eliminating comfort, sharp handling, and out-and-out speed combines with an ability to get off the beaten track."
"The level of smoothness on the Domane continues to impress, creating an experience akin to being chauffered around in a luxury sedan. It absorbs all road vibrations, operates quietly, and accelerates on flats deceptively quickly…I'll be in for a rude awakening after returning to a road bike without IsoSpeed."
"Fast on all terrain"
"I took the Domane on my local gravel and some select chunky bits to see how it would fare. The most notable transition from road to gravel was the sense of ease. Usually, when you roll from tarmac to stones, the bike can feel skittish and nervous (rider or bike). The Domane feels stable, and instead of holding your breath, you breathe out."
Whether you're riding solo, with a group, on smooth roads, or light gravel — here are the accessories you need to make sure your Domane is always ready.
Which generation is right for you?
Soar across long miles with our lightest Domane SLR disc yet on Gen 4 or roll with the comfort boost of front and rear IsoSpeed on Gen 3.
Dream bike. Dream build.

Born to win
Lighter, faster, and already a Paris-Roubaix champion.
The always-on team
Research shows the single most impactful measure you can take to stand out to motorists is to use front and rear Daytime Running Lights. The team uses them on every training ride, any time of day—and they’ve found that these lights truly make a difference.
There's a lot more to Trek than making the world's best bikes and cycling gear. Learn more about everything Trek is doing to make the cycling space safer, more inclusive, plus a whole lot more fun.
The smooth advantage.
Newly refined IsoSpeed soaks up fatiguing bumps and saves weight so you can ride stronger longer.
Raced to victory on the infamous cobblestones of Paris-Roubaix, the new carbon Domane is faster than ever thanks to new aerodynamic improvements and an ultra-light design.
Lighter than ever
Our best and lightest 800 Series OCLV Carbon and a new gram-saving design make this our lightest Domane SLR disc ever.
Versatile tire clearance
Comes equipped with fast rolling 32mm tires, but offers clearance for up to 38mm tires so you can confidently ride everything from smooth pavement to light gravel.
Internal downtube storage and top tube bag mounts make it easy to carry everything you need for all-day rides.
Domane is more integrated than ever, with hidden cables and a hidden seatpost clamp.
Shimano 105 Di2
With a shared Di2 platform inherited from Dura-Ace and Ultegra, sophisticated ergonomics, Shimano 105-optimized gear combinations, and an exceptional hydraulic disc brake system, Shimano 105 Di2 R7100 marks a new era of affordable, 12 speed electronic performance. You can set up the drivetrain just the way you like it via Shimano’s user-friendly E-Tube app.

Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.

Performance. Stability. Victory. Trek endurance geometry is a triple threat, maximizing control, handling, and responsiveness through perfectly tuned rider weight bias.

Flat Mount disc brakes
