Trek unveil disc-equipped Domane 4.0 and 6.9

American firm's first road bike with disc brakes breaks cover

Trek have unveiled the Domane Disc. The American firm’s first disc-equipped road bike is available in two models – the Domane 4.0 Disc for £1,600 and Domane 6.9 Disc for £6,000.

The Domane was first unveiled in March 2012 and is Trek’s ‘endurance race’ bike, developed in conjunction with Fabian Cancellara and ridden to a Tour of Flanders and Paris-Roubaix double by Spartacus in 2013. The Domane uses Trek’s IsoSpeed seattube/toptube decoupler and has clearance for 28mm tyres, and adapting the frame to take disc brakes is an obvious evolution for a machine designed for comfort.

The Trek Domane Disc is available in two guises: the entry-level 4.0 and, pictured, the flagship 6.9

The updated Domane Disc frame uses a 15mm and 12×142 thru-axle at the front and rear respectively, which Trek say ensures maximum stiffness, steering precision and rigidity. The disc-equipped road bike market is still evolving and we’ve seen some bikes with standard quick release axles, and some with thru-axles, and while the Domane Disc leans towards the latter, Trek have borrowed the ‘Closed Convert’ technology from their Superfly hardtail mountain bike range to ensure both the front and rear can be converted to traditional quick releases to maximise compatibility with aftermarket disc-ready road wheels.

The Domane Disc will initially be available in two guises: the Domane 4.0 Disc and Domane 6.9 Disc, made from Trek’s 400 and 600-Series OCLV carbon fibre respectively. Disc-compatbility aside, both frames retain the same features as the regular Domane, with that IsoSpeed decoupler, hidden mudguard mounts and a BB90 bottom bracket.

The entry-level Domane 4.0 Disc is equipped with a Shimano Sora nine-speed groupset with TRP’s cable-actuated HY/RD hydraulic disc brakes, Bontrager finishing kit and ‘Bontrager Approved’ tubeless-ready wheels wrapped in 25mm Bontrager R1 tyres.

The flagship Domane 6.9 Disc, meanwhile, is dressed in Shimano Dura-Ace Di2, with the Japanese firm’s R785 hydraulic lever and disc setup, and Bontrager finishing kit. The Domane 6.9 Disc also gets Bontrager’s new Affinity Elite TLR Road Disc tubeless-ready wheelset, with a 23mm-wide aluminium rim, interchangeable axle caps and a claimed weight of 1,655g. Those hoops are shod with 25mm Bontrager R3 tyres.

Trek road bike brand manager Michael Mayer said: “The response we’ve seen from riders about the Domane has been unprecedented and adding a disc brake option further opens the door for riders to expand how and where this bike is ridden.”
