TL;DR: Trek is adding a few Domanes with gravel-specific trims to address the growing gravel segment.
Originally developed in 2012 as an endurance race bike to tackle the notoriously rough cobbled classics in Northern Europe, the Domane’s unique frame-flexing IsoSpeed decouplers have proven its worth in smoothening out those bumpy rides while going fast… exactly what one would look for in a gravel bike.
With that in mind, the Wisconsin giant decided to spec a few of the Domane bikes specifically for the gravel crowd. At its base, the frame and fork are identical to the regular endurance road brethren, but the differences are the inclusion of tubeless wheels and appropriately spec’d 35mm Schwalbe G-One tires.
There are three models of Domane Gravels to choose from:
The $1,789.99 entry-level ALR 5 gravel features an invisibly-welded Alpha aluminum frame with front and rear ISOSpeed, an ever-dependable Shimano 105 groupset and TEKTRO Spyre flat-mount mechanical disc brakes. The ALR 5 comes in seven sizes from 50 to 62cm and the bike in 56cm weighs at a claimed 21.23 lbs.
The $2,499.99 SL 5 Gravel gets a 500 Series OCLV carbon frame with front and rear ISOSpeed, Shimano 105 drivetrain with RS685 STI shifters and RS805 hydraulic flat mount road disc calipers. The SL5 comes in seven sizes from 50cm to 62cm painted in what Trek calls “Matte Shady Grey” and the 56cm bike reportedly weighs at about 20.22 lbs.
The top-flight Domane Gravel, aka the priciest of the three, uses a higher grade 600 series OCLV carbon with front and an adjustable rear ISOSpeed decoupler for a personalized tune, Shimano Ultegra mechanical group with hydraulic disc brakes, and lighter components all around to make it some three pounds lighter than the SL5.
The Domane SLR 6 Gravel starts at $5,499 only as part of Trek’s Project One custom program, but the upshot is that you can customize it anyway you like down to the paint for a fee.
