Trek Domane 4 Series Road Bike

trek domane 4 series

Domane 4 Series flies past any other carbon endurance race bike in its class, with IsoSpeed for race comfort, endurance geometry for stability, and Power Transfer Construction for speed.


Smooth ride

Saddle White bar tape Heavy wheels

The ride is very smooth through the saddle, but a lot is transmitted through the handlebars. The bike is very stable on downhills up to my max of 44 mph. Upgraded the cassette and chain to Ultegra and shifting the rear became much smoother; cheapest maintenance change to do when your chain is worn. Upgraded the wheels to Dura Ace and lost about 1.25#; climbing instantly became better. Next upgrade is carbon handlebars 46cm and hopefully I'll get less road transmission into my arms. The dirty white bar tape will go away. The saddle was replaced early on with a Brooks. I average about 200 miles per week and do a significant amount of moderate climbing. So far there is about 7000 miles on the bike and I really enjoy it. I didn't give it a 5 overall because there is always something better out there, but this is the bike I'll be riding for a few more years at least. One of my better purchases. I recommend this for anyone looking for nimble, comfortable ride. Probably not for a racer, because lighter models are available.

No longer care if there is chip seal. Smooth ride for your butt. Good component set.

Race light wheel spokes do not hold up. Remember you are isolated from a lot of the impacts the bike is absorbing. Hands and feet still vibrate. Section of road with caterpillar track damage hurts my feet but the vibrations don't get to my seat. White bar tape immediately looks dirty. Bontrager seat is not comfortable. 4 series carbon not so light. Notice seat movement with cadence over 105. (but smoothed out stroke, originally noticed movement over 90 cadence). Carbon bike: SKS raceblade fender mounts mar the surface finish. I need to get the Trek fender mount accessory pieces.

Smoooooth! Good commuter and distance ride. Bet you will change out wheels and seat. Reliable and takes a beating so you don't.

Very stiff, very smooth, great handling. 6800 ultegra group is brilliant. Wheels feel excellent, stiff durable and smooth. Spokes are standard dt which will make replacements cheap and easy to source.

Seat hurt me, but others may like it...not a deal breaker.

2014 Trek Domane - I've been riding and racing for about 15 years, have owned 1 custom steel, 2 aluminum, 1 carbon and a scandium alloy bikes. This is a huge step up! The marketing jargon is true, the bottom bracket is as stiff as any bike I've ridden. However the isospeed REALLY works, I was even pedalling seated across stock grids! It handles great, and all (except stock saddle) the bits feel spot on. Oh and it looks great. It's actually a really nice pearlecent white which you can't see on the website. I test rode giant defy advanced, cannondale synapse, specialized roubaix. All the others were good, but this was the best, I don't want to change anything other than the seat. This was also the cheapest. Oh yeah I'm not little either with a fighting weight of 90 kg if it can be this good for me, I reckon it's pretty darn good. Highly recommend it.

This is a great bike. I like riding it.

Ultegra/105 components, superior seat vibration relief, light and stiff frame, metallic paint scheme.

None so far after 500 miles

Great mix of Ultegra and 105 components for this price range. The standout though is the Iso Speed decoupling, its no gimmick and definitely smooths out road chatter and bumps from uneven pavement. Its not a miracle cure and your hands still get rattled up on rough pavement but coming from a Synapse using the same saddle, there is a HUGE difference in what you feel transmit to your seat. The frame is beefy and offers great comfort for up to 63 miles, my longest since owning it, with just slight discomfort which I know my upcoming fitting will remedy. The frame has a BB90 bottom bracket, hidden fender bolts, a chain dropping prevention device (I've dropped mine 3 times, LBS says it needs adjusting) and will take 28mm tires which is my next upgrade and has been highly recommended. The other Bontrager RL components seem like good pieces so far.

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.

trek domane generation four

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 domane generation four

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.

domane 4 sl slr geometry

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 domane four

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.

Trek Domane 4.3 review

Vibration-damping road bike with IsoSpeed tech

We were blown away by the premium 6-Series Domane , which introduced us to the pavé-pancaking IsoSpeed fork at the front and decoupler technology at the rear. You get these on the 4.3 as well, and the bike finished in the top five of our 40 Cycling Plus Bike of the Year contenders :

Trek domane 4.3

Tech ed Warren Rossiter talks through the Domane 4.3

Ride & handling: Comfort without compromise

Any worries that a lower grade of carbon or spec would dilute the effectiveness and performance of the 4.3 are unfounded – it’s 1.8kg (4lb) heavier but also £5,200/US$4,430 less than the 6.9, and for £1,800/US$2,499 you get a simply astonishing frame and an addictive ride quality.

First ride impressions are fairly conventional, until you realise that the usual road chatter and vibration is muted to the point of being barely noticeable, although the road feel, so crucial to precise handling, is unaffected.

Arguably, the road feel was accentuated because the Domane seems to be in contact with the surface more of the time. Turning into corners on roughly patched tarmac was refreshingly undramatic, the wheels seeming to tuck in and bite instead of skipping across the surface.

With such impressive stability and poise, exploring the Domane’s limits becomes de rigueur on almost every ride. Go looking for rough stuff expecting to lose fillings and instead you’re cosseted by a sublimely floaty feeling.

Of course, on the most extreme roads there’s still an element of vertical movement, but sudden kicks and general vibration are removed. Not beating about the bush – the Domane’s ride is little short of astonishing.

Frame & equipment: IsoSpeed tech with functional kit

The IsoSpeed system doesn’t have a threshold below which it feels inert. There is no intrusive movement that could affect your pedalling action, as the active component of the Domane is the whole seat tube, not just the seatpost.

The decoupler is basically a rotational pivot attaching a lug on the front of the seat tube to the top tube, allowing the tube to bow and flex along its length in isolation from the frame, with no more effect on seating position than a slim carbon seatpost. The increased active length results in several times more shock absorption without the need for excessive movement in a restricted space.

Complementing the rear end is the IsoSpeed fork. This has a 1 1/8in to 1 1/2in tapered steerer tube for huge rigidity, and a constant radius curve that continues slightly ahead of the dropout to maximise its bump-smoothing ability.

Despite sounding like a full suspension bike, the Domane sports an oversized down tube and muscular asymmetric chainstays, which envelop a simply massive BB90 bottom bracket shell, and combined with the fork’s lateral stiffness make it as responsive as any fast road bike out there.

As ever, at this price there are some parts we’d quickly upgrade, and with so much technology in the Domane’s frame the wheels are the obvious place to start. The Bontrager Approved hoops roll well and resisted the worst we could fling them at with no problems, but they aren’t on the same level as the frame and are a little sluggish.

Shimano’s 105 was faultless as ever, though Trek still include an integrated chain catcher to prevent it dropping between chainset and bottom bracket. The exclusively Bontrager finishing kit is all competent stuff, but could benefit from judicious upgrading when budget allows.

That said, we’d gladly choose to take the Domane out more often than more exotic machinery because the frame offers so much comfort with no performance penalty. A stunningly simple but superbly accomplished design.

This bike was tested as part of Cycling Plus magazine’s 2013 Bike of the Year feature – read the full results in issue 273, available on Apple Newsstand and Zinio .

Review: Trek Domane 4.5 – A High-End Frame and Smart Build Kit

trek domane 4 series

While many brands have introduced “endurance” road bikes over the last few years, few have taken the idea to quite the extreme as Trek.

Trek Domane 4.5 – A High-End Frame and Smart Build Kit

The Domane was developed with considerable input from Swiss pro cyclist Fabian Cancellara , who is known for his steam-engine riding style, using his massive power output to crush cobblestones in the fabled Spring Classics. He is said to enjoy the bike so much that he rides it year-round, even in the Tour de France, choosing it over Trek’s racier Madone model.

The frame features the intriguing IsoSpeed decoupler , an ingenious system that separates the seat tube from the top tube and seatstays, and allows the seat tube to flex and pivot at the mounting point. If you stand next to the bike and put your weight on the saddle, you can see the seat tube flex slightly, but while riding it is imperceptible until you hit a bump.

A High-Performance Machine

Make no mistake: IsoSpeed is not a suspension system, and this is still a high-performance machine. If you’re expecting something akin to a suspension seatpost, think again. The frame’s ride quality is distinctly carbon—a muted road feel with less of that high-frequency vibration you feel from some aluminum frames, but still generally stiff.

Iso Speed makes itself most noticeable when crossing railroad tracks or other high-speed, sharp impacts that would normally require you to lift or shift your weight on the saddle to avoid being bounced. Not having to do that means you can keep your cadence smooth and the power high. The system seems so extreme some might think it’s a gimmick, but I’m convinced. Trek is as well—the technology will soon be adapted to its line of hardtail mountain bikes .

At the other end of the bike, the fork deserves some of the credit. It was developed with an asymmetrical steerer tube that is slightly thicker side-to-side than front-to-back, giving it a touch of compliance, but it never felt soft or shuddering.

The difference between the Domane 4.5 and the higher-end models is in the stiffness of the carbon fiber itself, and that this version uses a standard 27.2mm seat post rather than a seatmast that is integrated into the frame. I actually prefer the standard post, as it can be swapped for countless alternatives and provides an easy spot to clamp the bike in a work stand.

Trek’s DuoTap Hidden Speed

Other frame details include a spot for Trek’s DuoTap hidden speed and cadence sensor, an integrated chain guide to eliminate dropped chains and more generous tire clearance than most frames. It also has removable fender eyelets, so you can keep the clean look if you’re not using them. For an even smoother ride, you can ditch the tubes and set up the Bontrager Race wheels tubeless—another technology that is easy to dismiss until you try it.

It would be a mistake to write off the Domane as a “comfort” bike for weekend warriors. Despite accommodations for a smooth ride, it is as stiff and race-worthy as I could ask. Yet the slightly longer wheelbase makes it extremely stable, and it’s one of the few bikes I’ve ever plunged downhill at 40mph with a crosswind while still feeling relaxed. The fit adds to the comfort factor, as the slightly taller head tube gives you a more head’s-up position than Trek’s race bikes. Paired with a set of shallow-drop Bontrager handlebars , I felt great in each of the riding positions, an essential element of a long, comfortable ride.

Domane: Initial Acceleration is Direct and Instant

The adage “laterally stiff and vertically compliant” has gone beyond cliché to become something of a running joke in road bike circles. The notion that a bike can be a stiff-as-heck race machine and still be comfortable over rough pavement on long rides is not unlike a unicorn—a magical beast that surely can’t exist. But on the Domane, initial acceleration is direct and instant, with the massive, squared down tube and BB90 bottom bracket all but eliminating lateral flex.

Back in Issue #16 I reviewed the Volagi Liscio, which also features an unusual seat tube arrangement—the seatstays bypass the seat tube and connect to the top tube. While the Liscio was smoother than the Domane in a straight line, it can’t compete with the Domane in terms of power transfer and handling accuracy. The Domane makes no sacrifices in these areas.

The Shimano Ultegra build kit performed flawlessly, as I expected. The compact crankset paired with an 11-28-tooth cassette offers tons of range for tackling the steepest pitches. The 105-level brake calipers offer power to spare, as a single finger is often enough to bring the bike to a stop.

Hitting the street for less than $2,800, the Domane 4.5 struck me as a steal, considering the high-end frame technology and the smart build kit. While it will likely be pitched to riders looking for a high-performance ride for centuries and gran fondos, the Domane is a race bike at heart that won’t beat you up on the weekdays.

A Versatile Road Bike: Trek Domane 4.0

If you can only own one bike, this Trek might be the most versatile out there.

Trek Domane 4.0 $2,100,

Unless you’re planning to own multiple bikes, you’re going to have to decide between a triathlon-specific bike and a well-rounded road machine. The Trek Domane, however, offers a compromise.

This smooth-riding road bike is suited to finding the sweet spot between traditional road and tri positions. Slapping aerobars on a road bike often forces the rider into a scrunched position, resulting in a loss of power. The Domane’s geometry—handlebars higher above the ground and closer to the rider than many race-tuned road bikes—creates a conservative road position and facilitates an efficient aero position when coupled with clip-on aerobars.

Trek Domane SLR 9 AXS Gen 4 Review

Jason Mitchell

The 2023 Trek Domane went on a serious diet for its 4th generation. Now with just half the IsoSpeed as before, wider tires and a comfort-tuned carbon layup make up the difference on the Gen 4 Domane. In review for almost a year now, the Domane SLR 9 AXS is likely a shoe-in for 2023 bike of the year honors.

Trek Domane SLR 9 AXS Gen 4 Features:

  • 800-Series OCLV Carbon frame and fork
  • Rear IsoSpeed only
  • Aerodynamic Kammtail tube shapes
  • Integrated frame storage in downtube
  • Full SRAM Red AXS drivetrain with Quarq Zero power meter
  • Internal cable routing for a clean look (and watt savings)
  • Bontrager Aeolus RSL 37 wheelset
  • Bontrager Verse Short Pro saddle with carbon rails
  • Bontrager Pro IsoCore VR-SF 42mm bars
  • Clearance for 38mm tires
  • T47 threaded bottom bracket
  • Weight: 16.6 lbs (56cm, actual)
  • MSRP: $13,199

2023 Trek Domane SLR 9 eTap AXS Review

Domane SLR Gen 4 stunner

This particular frame and build kit represents the best that Trek offers in their Gen 4 lineup. At a $13,199 price point, there better not be anything left to be desired. No doubt, every box is checked with their highest-level wheels, components and paint. SRAM Red AXS is the best there is and an integrated power meter is a necessity for demanding riders. Including the versatile and fast Bontrager Aeolus RSL 37 Wheelset is also a great choice — even though someone paying this much for a bike may want a set of Zipp 353 NSW wheels. (As luck would have it, I tested those on this bike too.) That said, the Domane SLR 9 is for those with deep pockets or adept budgeting skills.  For more details you can ogle over the specs on the Trek web site .

While this spec is the best of the best, thankfully much of the performance I’ve come to love can be had at lower price points. The SLR models start at $7999 while the SL models start at $3499. Trek also offers Domane SLR, SL and RSL framesets should you wish to swap parts from your existing bike and/or do a custom build.

Trek Domane SLR 9 AXS Review

Utilizing Trek’s best 800-series OCLV carbon throughout, the Domane SLR 9 AXS is light enough to go toe-to-toe with many climbing bikes, yet comfortable enough to ride all day on all terrain. You’ll notice that the simplified IsoSpeed unit is now only in the rear and absent from the head tube. That alone dropped hundreds of grams off the frame. Tube shapes are now optimized for aerodynamics as well, for a true one-bike quiver.

2023 Trek Domane SLR 9 Gen 4 with rear IsoSpeed only.

Most high-end bikes now come with full internal routing from drops to stays. While the sleek lines do make for an amazing aesthetic, most of the time that type of routing limits stack height variations or cockpit changes unless you’re a skilled mechanic. Thankfully, Trek has outfitted the Domane SLR AXS with a separate bar/stem and unique cable routing that allows for cockpit and fit changes without much fuss. The secret is the Bontrager RCS Pro Blendr Stem , with its cable-concealing cover that hides and routes brake cables neatly through the head tube. Spacers can be inserted or removed and stem length/rise can be accommodated (within a reasonable range) without brake hose disassembly.

Fit and geometry

A quick note on the overall fit and geometry of the new 4th-gen Domane. As Trek’s most popular model, the Domane is built to fit everyday riders and high-octane riders alike. You can slam it or let your body dictate the right feel. For me, the geometry is as if it was custom-built. With two 5mm spacers and a 100mm stem, the reach is spot-on and I’m in the proper position to attack all types of terrain in absolute comfort. And, because it has a separate bar and stem, I can further change the cockpit as needed.

Something to note is that if you have long legs for your frame size, you might find yourself needing a longer seatpost than comes standard. I have a 30″ saddle height and that’s within a few millimeters of the max height. I don’t see alternative lengths available for purchase, but perhaps my sample bike inadvertently came with a shorter length?

Trek Store Fit Profile System

Compared to other endurance bikes, like the Cannondale Synapse Carbon 1 RLE and the BMC Roadmachine X One , the Gen 4 Domane looks and feels pro with minimal spacers. I love the sleek look, but most of all I love that I can get into the correct body position for best performance on the Domane. It’s not always that my 48-yr-old self can have a bike that looks sleek and pro and fits like a glove, but that’s what I get with the new Domane.

Of course, your best fit starts with your friends at your local Trek dealer, who can begin with their fit system and refine from there. Or, you can get fully-dialed with a professional bike fitter for maximum performance. (I use my friend, Jeff Sherrod at Precision Bike Fit here in Sandy, UT.)

2023 Trek Domane SLR 9 AXS Review - Pushing hard

First rides and more

As you should know by now, I actually ride test bikes and products for a long time before posting a review. I have the luxury of not being beholden to editorial timelines or advertising campaigns. With this bike arriving in August 2022, I’ve had it a long time. Utah’s epic snow year did draw things out — but that’s not the only reason. The real reason is because this bike is so much fun. So, beyond a first ride impression, this is a well-rounded review of how the Domane SLR performs on all types of terrain and conditions — including gravel.

My first three pre-launch rides went swimmingly. Each one was on roads and Strava segments I’ve ridden hundreds of times. At this point, PR’s and cups are hard to come by, but each ride had a handful with several other segments just barely off those top times. Call it “Domane Courage,” but my initial results had me convinced that there’s something to this new bike.

2023 Trek Domane SLR 9 AXS Gen 4 - Climbing

Let’s talk about climbing first since it’s obviously second-fiddle in that department to the Emonda. Long, mountain ascents are best served by a light and snappy climbing bike, but the Domane ascends quite capably. At 16.6 lbs, it’s not the lightest bike, but it still beats everything but the pure climbers. Aerodynamics, comfort and power transfer all add to the Domane’s climbing ability. I can settle into a rhythm and knock out even the longest climbs while seated or standing. I love mixing things up with a quick shift and standing to add variety and power through steeper sections.

Some endurance bikes feel floppy when standing and climbing, but not the Domane. The frame is rock-solid and all power is efficiently converted into forward motion without wandering or wonkiness. With all the efficiency, I still appreciated the 1:1 gearing on the steepest climbs, but didn’t use it all that often as I danced my way up most climbs.

When it comes to rolling terrain, the aerodynamic shapes and fast-rolling wheels come into play. Yes, the Bontrager R3 Hard-Case Lite 32c tires are a little wider than the Bontrager Aeolus RSL 37 wheelset, which does reduce aerodynamics, but they also aren’t the fastest-rolling treads on the market. Still, they are comfortable and durable, which usually wins the day. Back to rolling terrain… the Gen 4 Domane SLR simply shines at speed. Once you’re pedaling along at a good clip (18-21 mph), momentum is maintained and the entire bike just slices through the wind and keeps speed through undulating terrain. Not since the 2020 Specialized Venge Pro have I had so much fun on rolling roads.

Trek Domane SLR 9 Gen 4 AXS Review - Descending

Whether you’re coming back down the Utah’s Alpine Loop or descending a shorter hill, the Domane SLR delvers confidence beyond confidence on any descent. Speeds are deceiving because the ride is just so pleasant and planted. Trek has nailed the perfect combination of road feel and road dampening. It’s easy to point it where you want it and the bike follows — almost like it’s tapped into my brain. With some luck, wide open roads have been my reward and I’ve been able to open it up and spank any descent at speeds I haven’t hit in years.

Trek Domane SLR 9 Descent from Tibble Fork Dam

One of the keys to the Domane’s greatness is how well it handles. Most endurance bikes lack that race bike panache. They don’t track perfectly through tight corners while maintaining momentum or a progressive track. With the Gen 4 Domane, I have found it to handle as well as the best bikes I’ve tested. Yes, that means I’d stack it up against a Pinarello Dogma and the Specialized Venge Pro (two of my all-time favorite bikes). It’s as if the bike anticipates corners and allows me to angulate into and out of them in a whiptastic way. Momentum is maintained and it pops out of turns with speed. Winding descents are an absolute gas and I just can’t seem to get enough of them.

With excellent 1:1 gearing and stiff, responsive layup, I can climb up anything, roll through any roads and descend like a rock. Considering the Domane SLR’s body of work, I see it as the one to beat — by a clear margin. If you want an even racier Domane, you can custom-build the RSL frameset to your liking, but tire clearance is reduced to 35c on that frame.

Going from dual IsoSpeed to a singular, simplified unit does have some people saying that the new Domane feels less cushy than before. For me, it’s just right. Rolling at 55-60 psi with the R3 32c tires offers plenty of comfort and the IsoSpeed is icing on the cake. I appreciate Trek’s approach and the simplification this decision provides.

Graveling on the Trek Domane SLR 9 AXS

Domane SLR does gravel

With 38mm tire clearance, the new Domane is ready for all the local gravel routes and a wide variety of gravel tires on the market. With IsoSpeed, tubeless gravel tires and wide rims, comfort is outstanding. Instead of removing the Bontrager R3 tires, I decided to mount up a set of WTB Vulpine 36c tires to the Zipp 303 S Carbon wheels and give it a go. These tires measure out to 36.5mm and there’s plenty of clearance for even wider rubber.

I didn’t hesitate taking the Domane everywhere I ride other gravel bikes with even wider tires. Road approaches led to rolling gravel and winding singletrack. Across all terrain, the Domane responded with an adeptness I hadn’t imagined. One one of my first gravel rides, I hit a segment I’ve ridden nearly 150 times and got the third best time ever. I was floored. The Domane is not only fast and efficient on the road, but gravel too.

Cedar Hills to Valley Vista Trails Strava Segment

On singletrack, it feels just as capable as it does on wide-open gravels. The only thing I miss from my Open WIDE is the added flare from the ENVE SES AR Bars . Well, and I do miss a little more rubber to charge even harder on rough terrain. But, standing climbs, fast flats and descents are all tackled with capability beyond anticipation with an “endurance” bike. If you can find the right treads, I’d max them out at 38c and find yourself a second set of gravel wheels ( Bontrager Aeolus Pro 51 or Pro 3V are both great choices for easy swapping).

2023 Trek Domane SLR 9 AXS - Downtube Storage

For gravel or other long rides, the downtube storage is a huge bonus. With a flat kit in there and a few other small items, you can get away without a saddle bag and augment it with food or other items in jersey pockets. This storage compartment remains water-tight and keeps mud and dirt at bay. Plus, it includes a sleeve that’s set up to quietly carry tools and a flat kit.

Singletrack ahoy on the Trek Domane SLR 9 AXS

Alas, not everything is perfect

Now that I’ve showered the latest Domane with praise, it’s time to be nit-picky a little bit. Ultimately, my biggest grip is with the handlebar selection. In my opinion, an endurance/gravel bike should not have traditional drop bars. The Bontrager Pro IsoCore VR-SF bars included here feel like a miss-spec. Not only are compact drop bars more wildly popular, they would feel better on this bike and put riders in a more versatile position when riding in the drops. The C-curved drops feel dated and out of place on a bike like the Domane. Why the shorter and more comfortable-dropped Bontrager Pro IsoCore VR-CF bars weren’t spec’d is beyond me.

The proprietary seatpost and IsoSpeed system is greatly simplified from the adjustable one from years past and provides excellent compliance and comfort without sacrificing efficiency. However, after a few creaky rides, I had to empty a sinful amount of carbon paste on the post and seat tube to keep it from creaking. Thankfully, it did fix it. On top of that, the oddly-short seatpost for a 56cm size is a little baffling.

Fit: I’m 5’11” and 175 lbs, riding the 56cm. With the stock tires, running tubeless, I settled on 55 psi front and 60 psi rear. 

  • A beautiful combination of aerodynamics, efficiency and comfort
  • Handles as adeptly as most race bikes
  • Versatile tire clearance for all terrain
  • Simply flies down curvaceous descents
  • Tons of fun on gravel too
  • Downtube storage is an added bonus
  • Dropped a ton of weight over previous model
  • R3 tires are versatile and grippy
  • STABLE at speed without any twitchiness whatsoever
  • Creaky seatpost required a ton of carbon paste
  • Short seatpost maxes out at just over a 30″ saddle height on a 56cm frame
  • Why the compact drop VR-CF bars weren’t spec’d is beyond me

The Bottom Line: Trek Domane SLR 9 AXS Gen 4

It’s hard to imagine a better overall “bike” on the market today. The Gen 4 Domane has all the right mix of aerodynamics, comfort and speed to enjoy anything you can throw at it. At speed, it’s a hammer and it just devours mountain descents with Italian-like precision. It does yield a little to pure climbers when the roads tick upwards, but that’s only a mind game since the overall package is just so delightful.

I settled right into the new Domane like an old friend. The geometry and spec delivered a near custom-fit for my body shape and riding style. Above all, this bike is just plain fun to ride -- everywhere. While it shines on all terrain, I love the responsive, race-like handling without any twitchiness that's sometimes associated with a fast-handling bike. It's the right combination of all the things to elevate this bike to the top of the endurance bike class, in my mind. The Domane SLR 9 AXS is expensive, but the same performance can be had at lower price points.

That was with the stock Bontrager R3 TLR 32mm tires on the Bontrager Aeolus RSL 37 wheeset. When I ran the WTB Vulpine 36’s on the Zipp 303 S wheelset, I ran 38 front and 40 psi rear. You can do it!

i’m in Austin TX, i’m riding my Cervello P5TT bike, I’m about to buy a new road bike, one i won’t need to upgrade as i “want” more features. happy to spend the price tag of the Trek SLR9 gen 4, (there is a little wait on it though) just wondering if you would recommend looking at anything else in the same category ? TIA

You have some good rolling terrain and rough roads/gravel out there in TX. I can’t imagine a more versatile overall bike than the new Domane SLR 9. With it, you can ride everywhere, or just the road, if that’s all you typically ride. Trek really has checked off all the boxes here — it’s responsive and light, but also comfortable and smooth. I honestly don’t know of another overall bike I’d recommend over the Gen 4 Domane.

Thanks for the first class analysis. One question I have. If you had to choose, which bike would you choose: the classic Domane or the electronic Domane +? Which did you enjoy more?

I am currently faced with the choice of which version to buy. I have some reservations about ebikes, but the prospect of riding more flexible routes and more distance in the same amount of time and still getting out there is appealing to me.

Does the + really ride like a classic bike?

Curious to hear your feedback. Jan

Thanks for the kudos and a great question about the Trek Domane+ SLR vs. the Trek Domane SLR. Both are awesome bikes for sure and the Domane+ does have many of the great features of the acoustic Domane, but it doesn’t ride like the regular Domane.

Reasons to buy the Domane+ SLR: – Covering more terrain – A little help on longer climbs – It looks and feels as close to a regular Domane as it possibly can (but it can’t match it)

Reasons to buy the Domane SLR: – MUCH lighter – Smoother overall ride – Snappier and more lively ride feel – You don’t have to worry about running out of battery (~2 hours with lots of climbing like we have here in Utah) – Handles much more adeptly – Based on your country, the Domane+ may not have the level of assist that it does in the USA (28mph here, which is great)

I really, really liked riding the Domane+. It was a really fun bike. But unless I REALLY needed an eBike, I would choose the regular Domane every time.

Bike test: Trek Domane SLR 7 ‘Gen 4’ – covering some of the basics (part of a series)

The new Trek Domane was launched a few weeks ago. It’s a ‘road bike’ but don’t let that title limit your thinking. With clearance for up to 38mm tyres* and a list of other features, it will also serve you well on the gravel and other rough stuff…

“The IsoSpeed system looks a bit more refined,” he said, and I nodded.

“It’s sealed a bit better,” explained Nash, who has worked on every generation of the Domane since it was launched 10 years ago. For the latest, there’s only one IsoSpeed on Gen 4, and it’s at the rear (rather than front and rear, as has been the case in the past) and, Nash adds: “There’s a cover that goes over everything which we haven’t had before.”

Perhaps I’ve benefitted from the IsoSpeed but it doesn’t scream out for attention. If it works, great. If it impacts the ride quality, it does so quietly and effectively.

trek domane 4 series

The Trek/Bontrager site tells me this about the 32mm tyres and the Bontrager Aeolus Pro 37 wheels :

  • Maximum pressure: 70psi
  • Tubeless ready (phew, as that’s how they are fitted)
  • Sealant volume: 45ml
  • 37mm rim height
  • 21mm internal rim width
  • 28mm external rim width
  • The wheels are “Warrantied for life”, with “no rider weight limit”

But I’m missing my punchline, because I went to find the recommended tyre pressure for my weight (as I’ve used online pressure calculators before with, for example,  Zipp wheels and Goodyear tyres , while Pirelli have a similar chart ) but Bontrager only lists maximum for these wheels: “ 70psi ”.

trek domane 4 series

Yes, you can spend hours on this bike and not feel battered. The 32mm tyres, lower pressures, and perhaps the IsoSpeed contribute to that comfort factor. But, for me, knowing that my adventure in different locations didn’t have to end because of a gravel road (or rougher) gave me confidence to explore.

When I’m in Sydney I know where I can go without having to turn around because a road becomes a trail. But this bike took me around Wollongong for the week of the world championships and, later, the Sunshine Coast while on holidays, and more than once did I find myself on gravel and dirt… and it never bothered me.

Aero or add-ons

Much has been made of Domane’s new frame shape. The “Kammtail Virtual Foil (KVF) tube shaping and an all-new integrated cockpit for improved aerodynamics,” they say in the highlight summary in the launch documentation.

It’s what we’ve come to expect from Trek. Of course there are “improved aerodynamics” (and yes, Gen 4 is lighter and more comfortable… etc), but your intended use may vary.

trek domane 4 series

The Domane frame hasn’t quite been subjected to the numerous drillings that the aluminium of the ideal bike-packing rig, the  Checkpoint ALR5  (another Trek review bike that I’ll tell you more about in the coming weeks) but it does respond to the market’s demand for accessories.

trek domane 4 series

The range of road bikes…

With each Trek road bike launch the differences between the trio of offerings – Madone, Émonda and Domane – seems to diminish. The new Madone race bike is, of course, more aerodynamic (and more comfortable, and lighter). The latest Émonda is indeed lighter (and more comfortable, and more aero). And now the Domane is more comfortable… with aerodynamic and weight-saving advantages.

And so, we’re left to wonder: when will they all merge and become one?

The Ma-Ém-Do seems to be what Trek is striving for.

I’ve ridden them all over the years. I’m yet to try the new Madone (and supply chain issues continue to impact the first of the relaunched road bikes by Trek in 2022) but I do understand the benefits – and the intentions – of each in the range. Until now, the Domane has been the Trek bike I’ve ignored the most.

It’s a combination of elements that prompts my last statement and it relates to how this review bike handles external forces, like the road surface but, importantly, the wind.

At high speeds the Domane is a pleasure to ride, with its predictability a true asset. On steep downhills, even when there’s plenty of wind blowing, I’ve hit 80km/h or faster and the bike is stable; I feel like I’m in complete control. Not once have I had any cause for concern.

Stable in a range of situations

With 37mm rims, frame angles that are slightly more relaxed than I’m used to, and a fork that is practical (ie. offering tyre clearance) while also being attractive and aero, the Domane handles better in crosswinds than my Izalco Max. At high speed this bike sings and the wheels don’t get pushed around like others I’ve used recently.

When the bike was still in the workshop, Nash said he expected that the Domane would have a longer wheelbase than other road bikes (see comparison chart, below ).

There are several comments added to a couple of RIDE Media’s YouTube videos featuring the Domane where viewers have asked for more information about frame size. And it seems Trek’s site is steering customers towards larger-than-usual recommendations.

“I’m 5’9”,” writes Craig Whittle, “and Trek website is recommending the 56cm frame but all my bikes have been size 54.”

In response to Craig, Michal Waldner wrote: “This year I have purchased a Trek Emonda in size 54 despite Trek website recommending me size 56. I was able to try both sizes at my LBS and 54 fits me way better. I am also 5’9”.”

Similar sentiment has been sent in by others who are keen to find out more about sizing, and the recommendations from Trek (so far) have all been for a larger bike than what the potential customers have previously ridden.

It was stem length that stood out the most for me once the bike came off the workstand, and it wasn’t a visual cue. The first thing I noticed when I got on the bike was how short I felt.

My saddle was positioned the same distance behind the bottom bracket as I have on my bike, but the immediate urge was to stretch out more than I could with the 90mm supplied stem. This is mentioned in my first video review ( see below ).

At around the 25km mark of my second ride, I pulled into a carpark and nudged the saddle back only a few millimetres on the rails and, voilà ! Problem solved. I haven’t felt compromised on the Trek ever since. (Note: the supplied Bontrager Arvada Elite saddle measures 270mm tip to rear, while my Repente saddle is 280mm.)

Furthermore, with the slightly higher front end than my bike (Domane: 835mm vs Izalco Max: 820mm), we decided to build the review bike with the smallest of Trek’s supplied, integrated stem spacers. (You will also notice that, rather than the neat, Domane-specific top cap over the stem, there’s extra fork length and a round top cap… because, as this is a review bike, we left some wiggle room and didn’t cut the fork too short in case the eventual owner want a slightly higher position.)

Spending longer in the drops

When I ride, I tend to switch hand position regularly: on the hoods, in the drops, and on the tops. Of course, this depends on the conditions, but I’d say my most common hand position is on the hoods… at least that’s how it has been over the last two years during the drought of review bikes.

With the Domane’s slightly higher front, I am gravitating to the drops more and more.

It’s different to my bike in many ways, but I’m comfortable on this Domane.

This is an all-day bike. It is comfortable and it does feel fast. But for me the biggest selling point is just how stable it is. It is also very versatile, and a great solution for a bike that meets many of my desires for the kind of riding I’m doing in 2022. If I wanted pure speed, I might look elsewhere in the Trek catalogue but I’m confident the latest Domane will suit more riders than the race-orientated Madone.

Trek’s ‘climbing bike’, the Émonda, might be slightly lighter and have other benefits… but, in my appraisal, the new Domane is not just a great bike for all-day comfort. It is, quite simply, a great bike. And in 2022 it is the Trek road bike that I would put at the top of my wish list.

"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."

"Smooth operator"

"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."

No image available

"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."
