Trek brings you the brand new Domane series and now this bike is faster than ever before, ready to take you to new heights of performance. Featuring Trek's IsoSpeed technology now means you can ride further, faster and longer while experiencing less fatigue. With front AND rear IsoSpeed, the shock absorber means your arms don't get as fatigued and the energy your body normally wastes here can now be used more efficiently so you can achieve tons of personal bests! The Domane can now fit tyres with up to a width of 38c to give you a faster-rolling speed and more confidence on the road. Trek has also added an internal storage compartment to allow for all your puncher kit to be placed inside the frame, meaning you've got more space for everything else you need on those long training rides. The Domane features Trek's 500 series OCLV lightweight Carbon frame to bring you a great upgrade from an aluminium road bike. Finally, with hydraulic disc brakes that allow for smooth and controlled braking, you're all set for a fast and furious riding adventure!
Domane SL 4 Disc is the introductory carbon model in the family, but when you make the small jump up from aluminium models, you get a big jump in tech, including a much lighter frame, Front and Rear IsoSpeed, a full carbon fork and the added stopping power and tyre clearance that disc brakes provide.
All the Technology
A 500 Series OCLV Carbon frame with road-smoothing Front and Rear IsoSpeed, a stable Endurance Geometry, powerful flat-mount disc brakes and a 2x10 Shimano Tiagra drive train. Plus, a micro-adjust seat mast, mudguard mounts and Tubeless Ready wheels wrapped in wider 700x32 tyres. Internal storage and cable routing add to the bike's capability and sleek look.
The unique IsoSpeed Carbon fork, swoops forward toward the dropouts and absorbs vibrations from the road so your arms won't fatigue as quickly. Riding over cobbles becomes less of a shock to you and a lot smoother as well as making those bumpy roads less of an issue and now a more comfortable experience.
