Taking their existing endurance road bike platform to the dirt, the all-new Trek Domane Gravel borrows the IsoSpeed flex points but with larger tires to make it fully capable off the beaten path. Or, at least, off the paved path.

2018 Trek Domane Gravel SL5 carbon fiber gravel road bike

Using the same frame and fork as the road-going Domane, the Gravel version subs in wider Schwalbe G-One Allround 700x35c tubeless tires and specific spec builds suitable for offroad use. Specifically, they come with Bontrager’s tubeless ready wheels or rims, 50/34 compact gearing and disc brakes.

Three levels of frames are available. The Domane Gravel SL5 carbon, shown above, is the upper mid level offering in a line of three options with their 500-series OCLV carbon. It comes with a full Shimano 105 group with flat mount brakes and has IsoSpeed on the frame and fork. Retail is $2,499, claimed weight is 20.22lb (9.17kg).

2018 Trek Domane Gravel SL6 carbon fiber gravel road bike

Upgrade the frame to a 600-series carbon Domane Gravel SL6 and you not only get better, lighter carbon, but also the adjustable rear IsoSpeed decoupler, letting you custom tune the amount of added compliance the system provides.

It also gives you a full Ultegra mechanical group with hydro disc brakes, starts at $5,499.

2018 Trek Domane Gravel SL6 Project One carbon fiber gravel road bike

The trick is, to get the SLR6 Gravel, you’ve gotta go through their Project One program, available only with the SL6 frame. This one’s got army green paint with SRAM Red eTap and will definitely cost more than $5,499.

2018 Trek Domane Gravel AL5 alloy gravel road bike

For the more budget minded, there’s one alloy option called the Domane Gravel AL5. You still get the IsoSpeed on the frame and the IsoSpeed carbon fork, and a Shimano 105 group, but it subs in mechanical Tektro brake calipers. Retail is $1,789.99, claimed weight is 21.23lb (9.63kg, size 56).

If you need convincing it’s totally awesome, there’s this video:

All three are available now. Or, if you already have a disc brake Domane, just throw some bigger tires on there.

    Just a lame stop-gap effort by Trek since they decided to ignore making a dedicated gravel bike.
    I expect they will have something legit in the very next year.

    Get the Boone or Crockett, their cross bike with geo very close to a “gravel” bike – 68mm bb drop, 72deg headtube angle on a 56 frame. $3300 for the Sram Rival 1×11 version.

    Why are people always skidding in these d*mn marketing videos? I ride gravel all the time and never do this crap they seem to imply is part of the riding style. I have disc brakes for crying out loud.

    Contrary to all the comments, this bike actually is compelling. There is nothing about gravel riding that requires a “slack” geometry. This bike provides the tire width to handle majority of gravel roads while maintaining an agressive all-round geometry that’s fun on the road but dialed down from crit sharp. IMO, the slacker “gravel” bikes are just hipster marketed rigid mountain bikes

      The Domane’s geometry is plenty slack & stable enough for gravel riding, and it doesn’t ride poorly, like so many of the new “gravel” bikes out there now. I’m most excited about the paint jobs. Finally some good bikes that aren’t covered in racer-boy graphics…

    It may check a few of the boxes to work as a gravel or all road style of bike, however, it is still sold by a company that doesn’t play nice with independent bicycle dealer’s. That is reason enough for me to never buy a bike with that logo on it. Additionally, there are plenty of other bikes sold by companies with integrity that are most assuredly more capable when the going gets rough and loose.

    Too little too late.
    Trek needs to be a little more bold. Finally able to use a 34 tooth small chainring, 4 years too late. Not enough room for 40C (or larger) tires, 2 years too late. They make awesome products, very slow to react….

      Finally? Maybe I’m living under a rock, but hasn’t the domane always been able to run a compact crankset (34t inner ring)?

      The only limiting factor is really the braze-on style clamp hanger, and I really really doubt Trek limited that to a 53t or 52t chainring (as FD are adjusted on the big ring…their geometry allows them to drop down).
      I can see being limited to a 50t big, but for the majority of people, this is fine (34t inner). Its a rough ROAD bike that will work very well in normal dirt/light gravel roads. Roads people have been running regular road bikes, shod with 25-28mm tires, for ages. Its not a bikepacking bike. Gearing below a compact doesn’t match the bikes intent.

    Please check the accuracy of the specs listed in this article. I spotted so many inaccuracies, it would take too much time to list. Bikeradar has it right.

    To start with, the Domane maxes out at 32c with Discs, not the 35c listed in this article.

      Mitch, if you were to believe the Q&A on Trek’s site for the standard Domane, then yes, 700×32 would be the max recommended tire size. However, they themselves are spec’ing a 700×35 tire on this “Gravel” model, and the Q&A on the bottom of the SL5 model’s web page has Trek’s folks chiming in to say that it can indeed run the 35mm tire. So, it’s a little confusing, but it would appear Bikerumor has it right also. Thanks for reading.

    Note that the AL version comes with an “isospeed fork” which is not the same as the front (headset) decoupler on the carbon frames. Darn.

      @Tom in MN: IMO, that ALR frame — but with front (head tube) IsoSpeed — would make the best actual gravel bike from Trek (cost/comfort/durability), but my guess is that we’re at least one more model year away from seeing that. :-/

    I would rather buy the Spez Diverge over this bike, as it’s far more capable. That’s if you want something from one of the big 3. My personal choice right now would be the Lauf Grit SL for a gravel bike.

    Reply
    • Dinger on

      Capable in what way? It can handle a few mm’s more tire, but it’s much heavier and noticeably slower over anything but the roughest surfaces it can reasonably handle. For that reason, I’d call it less capable.

      The Lauf is pretty cool, but cost of entry is much higher.

      @Joey B: The carbon Diverge Comp is priced $500 over the similarly spec’ed Domane SL5 Gravel and that Spesh Future Shock needs to be serviced every few hundred miles.

      But what really scares me away from the Diverge is that Spesh has this terrible habit of dropping maintenance parts for their weird/proprietary tech. I’d want to get a drawerful of Future Shock rebuild kits if I bought one of the current Diverge models.

    They call it a gravel bike. Then they don’t do anything to make it clear tires any bigger than 35mm; if you can’t fit 40C at the minimum, you can’t call it a real gravel bike. End of story.

      What? That’s ridiculous. Just like mtb’s and road bikes there is a large range of use. Many people will run a mix of pavement and dirt. Not every dirt/gravel road is 2″+ chunk limestone. Why would one handicap frame design to run tires they will never need?
      It’s not like trek is lying about the tire sizes it can fit

      Someone can always buy a Crockett if they really want to go hardcore off-road with the bike. But honestly, how much tire do you really need on your average gravel ride?

      Reply
    • John on

      @Steve F: That front (headtube) IsoSpeed is the real deal. If the ALR bike had that, I’d say maybe save yourself the $700 but, as it is, the SL5 is far-and-away the best bang for the buck, especially considering the upgraded brakes and shifters.

    what even is a gravel bike. it’s the market that demands these artificial marketing categories.

    you cant buy a tablet PC, you have to be marketed an i-pad to “get it”.

    and why would someone run 40c boat anchors on a gravel bike? seems slow.

      Why 40s? It all depends on where you ride……

      “A 36mm-wide 700C tire works in a great many situations. A great many. But for all the riding I do east of the 101 in Sonoma County, it’s just not enough tire. There have been too many (okay, a half dozen) occasions when I’ve hit a rock hard enough to make the rim bottom out against it.”

      On some of the dirt roads in my area, I’m a lot more comfortable — and faster — on a 29r hardtail with 2.3″ tires than a cross bike with 34s. On other roads it’s the opposite. Rolling resistance on smooth surfaces and weight matter less as the roads get worse.

    I like the geometry (Boone and Crockett are two racey for me). But I do require 40s and ideally a 45 for my next gravel bike. This is too close to my road bike to justify another frame. Just buy a second wheelset. Also, cross today is a 50/34 and 11-36. I know it’s easier to do a 1x 10-42 and then pick a chainring to match. Fire roads and gravel trails around here (western VA) are too steep and rutty for anything less. Norco Search XR looks to check the right boxes, if priced about $500 more than it should be.

    It seems to me that Trek has been dabbling in the gravel market for at least three years. At one point they guided you to their cross bikes, the next year they came out with their adventure line. Which included the 520, 720, and 920 disk. Last year they had a gravel category. It included their cross bikes, three models of Crossrip(which have a tire clearance of 40mm without fenders) and all models of Domone. This year they list the cross bikes and all models of Domone. Crossrip ended up in their hybrid category. Does that mean it’s similar to a Salsa Fargo? I think most bikes can be used for gravel. Depends mainly on racing gravel. It would seem that a drop bar mountains bike like the Fargo would be the good one for a race like the Dirty Kanza.
