Trek Doman Disc

Trek has rolled out a disc brake-equipped version of its popular Domane endurance road bike. The new rig comes in 4.0 and 6.9 iterations, has post mount disc brakes, and thru-axles front (15mm) and rear (12×142). It’s the Wisconsin-based company’s first disc-equipped road bike.

Like previous versions of the frame, the new bike utilizes Trek’s IsoSpeed decoupler, which separates the seat tube from the seat stays, allowing for subtle flex during rough road conditions.

To keep wheel options as wide open as possible, Trek’s employing its “Closed Convert” drop-out technology, which allows for conversion back to traditional quick-release set-up.

The top-tier Domane Disc 6.0 (MSRP: $7,900) has a 600 Series OCLV carbon frame outfitted with a Shimano Dura-Ace Di2 drivetrain and Shimano’s R785 hydraulic brakes and levers, and Bontrager’s new Affinity Elite TLR Road Disc tubeless-ready alloy wheels.

The 4.0 version (MSRP: $2,100) uses a 400 Series OCLV carbon frame spec’d with a Shimano Sora 9-speed drivetrain, Bontrager wheels and tires, and TRP HY/RD cable/hydro disc brakes with 160mm rotors.

Standard rim brake Domanes will continue to be offered in five versions. Here’s full spec details for both new bikes.

    That was my first reaction, too. They could have gone with 105 and made it a bit less insulting for the price. The only component worth keeping are the brakes.

  • John says:

    Shimano won’t be shipping their new 11-speed mechanical shifters w/ hydraulic brakes until August.
