    2020 Domane Gravel build

    2020_Domane_ProEndurance_60cm_side.jpg


    With the 2020 Trek Domane SLR gaining so much tire clearance, I saw that it fit my needs for a gravel race bike perfectly. I don't bikepack but I'm looking forward to running fenders on it for wet winter road rides. Integrated fender mounts make this a breeze.

    Standard Domane Endurance geometry was too tall for me. The lower Pro Endurance geometry only available through their Project One custom site. Splashed some flashy paint on it while I was in there

    60 CM Pro Endurance geometry
    Dura Ace Di2
    D/A power meter 180mm cranks
    Ultegra 46/34T
    D/A 140mm rotors
    Ultegra RX805 clutch derailleur
    D/A front derailleur
    XT 11-40T cassette
    Bontrager 42cm x 12cm XXX one piece carbon bars
    Specialized power saddle
    Crank Bros Egg Beater 11 pedals
    Carbon cages

    DT240 hubs
    Sapim CX ray spokes
    Light Bicycle 23mm internal carbon tubeless
    Michelin Power Gravel 35c

    Weighs about 18.5 lbs. I knew the build would be a bit heavy but comfort and durability is far more important at mile 150 in Dirty Kanza than a few grams here or there.

    Tire clearance in rear is 54mm. The Michelins measure 37.2mm on my wheels. Easily room for a 40c pushed out to 42mm on a wide rim. Running fenders will require smaller tires of course. Winter road plan is 28c GP500 tubeless

    Build notes:
    FD adjustment slot would not go low enough for 46T chainring. Had to file it about 2mm lower to get correct FD height.

    Cables are easy to run despite being all internal. Didn't even need my Park IR 1.2 cable routing kit that every other IR bike I have built required.

    On all my Di2 bikes I install the wireless transmitter between the bars and TT. This allows easier service but also lets me unplug shifters from battery. For any Di2 owners who have inadvertently drained their battery by storing the bike against a Di2 trigger..

    T47 threaded BB is awesome!

    Storage roll in DT is way too small for gravel tube. Barely enough room for road tube. I plan to find a small pump that will fit in there. Ordered the Bontrager BITS multitool that clicks into the cover on the inside.

    Better yet, get a 650b wheel set so you can run larger tires with the fenders.

    I have no need for large tires with fenders. Only need fenders for road riding in the rain on 28's.

    Personally, I have no interest or need for tires wider than about 40c. Everyone has their own preference, riding style and preferred terrain.

    Sweet build. I'm not a flashy orange kind of guy, but everyone has their color preferences. I really like your choice of components, and the nice clean look.

    I abso-freakin'-lutely love the color choice! Being a child of the '80s when neon colors became a thing, I've always wanted a bright orange bike.

    I can only dream that my boring black 2020 Domane will somehow magically change colors

    OK, I misunderstood and thought you may have wanted to keep a similar tire width that you use without the fenders.

    I like it. I identified the same potential when I saw a SL version in a local shop. I also see people are doing something similar at a much lower price point with the new Giant Contend AR, which has the same tire clearance. Both seem like great mixed terrain bikes. Specialized has to be hating themselves for limiting the new Roubaix’s tire clearance to 33mm now.

    Beautiful build! And 18.5 is not heavy by any means for a gravel bike. I personally want room for more tire in the front, not the rear but everyone has their own preferences. Sure wish someone would come out with a good sub compact crank dual sided power meter. Did you build it from a frame up? If so curious why you didn't choose GRX components and a more gravel specific handlebar?

    Rashadabd,

    Yup. The days of the single purpose road bike might be over. The folks that don't race aren't even aware of the massive tire clearance, aren't concerned with a few grams of extra weight and oh looky, rack mounts!

    Thanks. The cranks on this bike are dual sided power with a 46/34. Not cheap but flawless function and will last forever. As a bonus, Ultegra rings are way less expensive than D/A. I imagine a non series or Ultegra power meter crank is on its way from Shimano. Cranks are a fraction of the cost though, the expense is in the meters.

    Yah, frame up build. If I am only switching one or two components, it's cheaper to buy a complete bike. In my case, I wanted everything but the shifters, FD and calipers to be custom.

    Not a huge fan of the flared GRX shifters. Still prefer road hoods even for gravel. JD/A is also quite a bit lighter. Just personal preference.

    Also not a fan of flared bars. I ride gravel like I do road. I race cyclocross and use standard road bars there too, 3T Ergonova carbon to be precise.

    The 46/34 is still a compact crank not sub compact which is what I would like to see. 46 or 47 / 30 or 31 combinations are perfect for gravel IMHO but it depends on the grades you have around you - if there's nothing long over 10% compact gearing works fine for me.

    I didn't realize the GRX Shifters are flared, thought that was just the bars? Personally I like the 785 shifters better than the current versions of Di2 Hydraulic because they are wider and distribute the weight better, but haven't had a chance to put my hands on the GRX shifters yet. I like that the GRX shifters put the hidden button on the inside instead by the thumb of the top, that's a great design change they should do with their road shifters too.

    The asymmetric 110mm BCD on 11s Dura Ace / Ultegra / 105 allows anything from 34-44t inner and 42-56t outer. I run the exact same crank on my road bike (Cervelo S5 disc) with 52/36 and will run a single 42t ring on my cyclocross race bike. Quite versatile.

    Dura Ace have the hidden buttons under the hood. That's where that feature made its debut several years ago. Not sure if Ultegra has them. I use that button for switching pages on the Garmin.

    Visit the Shimano site for more info.

    i am very familiar with compact cranks and the Dura Ace power meter - I want a crank based SUB compact power meter like a GRX crank not compact / 110BCD. There's probably a dozen options for compact / 110 BCD crank based power meters, I already of 2 of those (Power2Max and Pioneer). Sub compact small rings are 30/31/32, not 34.

    Ah. That's sorta MTB territory. I ran XTR 2x cranks on my gravel bike for a while just for that reason but those were single sided. Used Wolftooth custom rings. Had a 28/44 on XTR 10s. That's a tough one, 31t and dual sided. I'd start a new thread on the MTB section to see if anyone has an option. Good luck.

    nobody makes them right now, lots of people looking for them. My money is on power2max or Easton to be the first to the market with a set. For now I use my power2max compact.

    40c on 2020 Domane

    Got the 40c Ramblers fitted, 41.2mm actual on these rims. Roughly 6mm clearance on either side, both front and rear. That's at widest point. Chainstay clearance is curved so less clearance at other points on casing. Plenty for slightly muddy conditions. Wouldn't want to go much bigger in heavy mud. Guessing you could safely stuff a 44mm tire in there in dry conditions for a light to medium rider. Heavy riders tend to flex wheels more thus more likely to get tire rub out of the saddle.

    None on that particular route. It's pretty much all Cleveland National Forest.

    Good coffee in OC though. Scouting some more urban/mixed gravel routes for a ride I want to put on. Start/finishes at a brewpub with 40 taps, french bakery at halfway point. Should be fun.

    4000 to 6,000 ft range about 20 miles inland, southern California. Eastern border of Orange county. I live and work at the base of the Western slope. In the distance is the 1500 ft coastal range where I rode the Domane yesterday. Spectacular panorama's of the hazy blue Pacific. Tough living but someone has to do it
