2015 Trek Domane Disc brake endurance road bike

The new Trek Domane Disc ushers in the latest road bike stoppers on a bike that was all but made for such things.

The Domane, which we’ve reviewed here, uses Trek’s IsoSpeed coupler at the seat- and top tube junction to separate bumps and vibrations from the rider and create a suspension effect. The bike’s made for the Classics like Paris-Roubaix, with clearance for big tires…and this new version adds spacer for even bigger rubber and fenders than before.

It also adds 15mm and 12×142 thru axles front and rear, but, the rear’s able to be converted to standard quick release thru axles to work with the vast majority of wheels currently on the market. Brilliant!

2015 Trek Domane Disc brake endurance road bike

The Domane Disc will initially be available in 4- and 6-series trims, which primarily means a difference in quality of OCLV carbon fibers used.

UPDATE: It also means the use of a seat mast design on the 6-series, which Royce Beckon, Trek’s assistant road brand manager says makes a massive difference in overall compliance compared to the 4-series’ standard seatpost design. The 6-series also gets their asymmetric steerer (ovalized just above the crown to be wider side to side than it is front to back, giving it better fore/aft compliance without hurting steering precision), full carbon fiber fork. That’s versus a symmetric standard carbon fork with alloy steerer on the 4’s.

UPDATE: While they mention room for bigger tires in the initial PR, we’ve been told the officially recommended maximum size is 25c in order to comply with CPSC and CE clearance guidelines. That said, you’re free to do what you want (at your own risk), and the pics suggest there’s plenty of room in there.


The Closed Convert Dropouts have been used on the Superfly hardtails, and now they make their way to the road, and to the front of the bike but only for the rear. Fork is 15mm thru axle only…which means new road disc wheels from Bontrager. Read on…

UPDATE: The fork also uses the Closed Convert dropout system, allowing for a switch between 15mm thru axle and standard quick release. Even better, the dropout inserts can be used on either side, letting you run the thru axle’s clamp on left or right, depending on your preference. For those new to disc brakes, the skewer/axle on the front is typically inserted from the right so the lever is opposite the disc brake caliper, a switch from standard rim brake setups.

As impressive as the top level Domane Disc 6.9 is, the 4-series is just as exciting for it’s $2,099 price point. So we’ll start with that:




Retail on the Domane Disc 6.9 is $7,899.99 and is decked out with pretty much everything you’d want. The upgrade path on this bike is short, and certainly not rushed. And while almost 8K seems like (is) a lot, in this day and age for a top level rig, it’s pretty fair.



What’s important to note here is that you get an OCLV carbon frame, tubeless ready wheels, the convertible dropouts and IsoSpeed tech with quasi-hydraulic brakes for just $2,099.99. That means a very budget bike that’s entire upgrade worthy as resources allow. The drivetrain would be at the top of our list since it’s apparently how they’re bringing it to market for so cheap: Sora 9-speed. Yes, nine speeds. Remember those?

Now, the bad news: If your local Trek Dealer hasn’t already ordered one, particularly the 6.9 series, word on the street is there will be a slight delay in you getting one of the more common sizes.



Bontrager’s been doing road tubeless for quite a while, and now they have a fresh upper mid-level alloy wheelset to go with the road bikes. The new Affinity Elite TLR Road Disc use their stacked, straight pull spoke system at the hubs with asymmetric placement at the rims for better bracing angles and a stiffer wheel.

The hubs use interchangeable axle caps, with options available separately, letting them run on various bikes. Our guess is they’ll show up on the Crocket before too long. Which brings up an interesting point…this new Domane is their first road/cyclocross offering to get thru axles, but we suspect the ‘cross bikes won’t be far behind.

The rim is drawn from 6061 aluminum and measures 23mm wide (17.5mm internal) and is laced with DT butted spokes. Both are laced with 24 spokes. Claimed weights are 740g (front) and 915g (rear), putting the total at 1,655g. They’re 10/11 speed compatible and a Campagnolo freehub body is available separately. No rider weight limit.



  1. There’s a new wheelset for them on there aswell! Affinity elite, more than likely tubeless and a wider than average profile, looks like the rhythm elite hub too.

    New paradigm RXL there by the looks of it too, bridge the £100 gap between the rl and rxxxl

    Takes a lot of things from the Boone, Inc cable routing and looks like the fork too.

    I’ll be a fan if more than a handful are brought to the UK!

  2. There is actually a pretty big difference to ride quality from a 4 to a 6 series – I think you missed the change from seat post (4 series) to seat mast (6 series). Makes a huge difference to ride feel beyond the difference to quality of OCLV fibers.

    But this is certainly a cool development.

  3. With that obnoxious correction out of the way, I’ll say that this looks like a very nice Gran Fondo bike. For my own purposes, I wish they made the Classics Edition geometry a standard feature, as I feel like I’m sitting in a recliner when I’m on the regular Domane. But that probably just means I’m not really the target buyer for this one.

  4. forgive me my ignorance, why are the thru axles coming into use more and more frequently?
    Also would love to hear more information re: the post / mast (ElPablo) impact on ride quality.
    assume mast would isolate rider better then post??
    Lastly comments regarding the tubeless wheel tire set up? vs tubes … anyone??

  5. We’ve just built one up – very cool… Comes with all the adaptors for QR too, but the new wheels look solid. Total weight – 7.5kg. (more pics on the Cycles Galleria Facebook)

  6. Hey Tyler: it is called IsoSpeed…not IsoPulse. And according to their launch info, both the front AND rear are convertible to QR, not just the rear. And just like ElPablo said, the differences between the 4 Series and 6 Series frames lie much more than just the level of carbon used.
    All that being said, I’m very excited about this bike. Hopefully these will sell like crazy and Trek will bring discs to more models!!!!

  7. Get real. $2100 for a budget minded road bike is absurd. Some of us in the real world ride on our own dime. How soon do you want me to upgrade to a thru-axle standard for road bikes? Oh, just for the rear wheel? Gimme’ a break.

  8. Finally, thru-axles front and rear on a disc road bike! I love my Spec Crux Pro Disc, but I often get disc rub from the front when cornering hard (no matter how much I carefully true and align the rotor). Never happens on my mountain bikes with thru-axles. New I should have waited one more year to buy my first disc road bike…

  9. Gumby – just taking a spin with flat pedals on a 4 series vs. a 5/6 series you can tell a noticable difference. The 6 series even feels like you might have to adjust saddle height for sag (a la mtb rear suspension). Certainly a larger impact for that style of bike and imho worth the money upgrade.

    Richard Johnson – $2100 for a budget carbon road bike is not bad at all, current entry level carbon road bikes are in the $1400 range but you make concessions from group set, cockpit parts, wheels, ect. Once you hit $2K you at least get to current standards and features (short of Di2) just without the fancy weight weenie bits & considerations. And again just my $.02 and always, imho.

  10. Not a big fan of the zip ties on the fork. Why not make it internal like on some I’ve seen. It feels a bit cheap to me. Might be easier to service but the rest of the cables are internal.

  11. So I get all warm and fuzzy about this bike and I click the Trek website. And SUPRISE, this bike isn’t on the darn webpage. So I guess I’ll do the usually and just wait until March 2015 when the bike actually becomes available. Oh Christ do I hate this aspect of the bike industry. Hey Bike Rumor, do us a favor, only review products that are actually available to buy at the time you review them….

  12. The Disc Domanes are actually already available. Trek has every size in the 4.0 in stock, and some sizes on the 6.9.

  13. In the uk we have the boardman pro carbon which is an excellent bike , ideal for upgrades and only costs $1400

  14. I really hate SORA! Why would they not offer a Domane with the new 11 speed 105 5800 and the new shamano mechanical hydraulic disc brakes?

  15. Pretty much my dream bike. I’d buy one in an instant if these came in a Di2 Ultegra build. At my level I just can’t justify the Di2 Dura Ace price point. LOL!

    @Doug McKibbon: The 2014 Di2 Domanes have been coming stock with internal batteries via seat post mounts. The Di2 Boones came with a new internal battery mount option in the seat tube but just above the bottom bracket. I would like to see the underside of the bottom bracket or the back of the seat tube to see if the Disc Domanes got the same treatment. Hopefully this link works: bikeradar.com/uk/road/gallery/article/exclusive-trek-boone-9-disc-first-ride-review-39503/17/

    That said, any guesses on how long it will take for the Boones to get these same thru-axles?

  16. @Casey: The Shimano ST-RS685 hydraulic/mechanical shifters aren’t due out until August, I’m guessing we won’t see the 6800 or 5800 groupsets on these bikes until then.

  17. @John: I am wondering when the Boone will get thru axles as well. They only released the Boone at the end of the US CX Calendar last year and you would have figured it would have been part of the equation. For me that is the only thing lacking.
