Lightweight and stiff, OCLV 500 carbon soaks up road vibrations and provides a comfortable ride.
Reliable, precise and efficient, this 11-speed setup never misses a gear change.
Dampening units in the seat tube and head tube markedly reduce rough road vibrations.
Room to fit high volume 38mm wide tyres allows the Domane to tackle the roughest roads.
Trek Domane SL 6 Disc Road Bike 2021
Trek's latest Domane SL 6 Disc Road Bike includes updated IsoSpeed front and rear as well as clearance for 38mm tyres. This is a bike designed with an Endurance geometry that gives up nothing in terms of performance. The aero tubes and internal cable routing keep drag low, while the carbon construction is light and stiff. Supplied with tyres of a 32mm width, rolling is fast and smooth, but you can go wider still - up to 38mm - and benefit from improved comfort on the roughest roads. Trek has introduced internal storage on the downtube - enough to fit everything you need to fix a puncture - so you can store only what you need close to hand in your jersey pockets.
Shimano's second-tier Ultegra groupset brings smooth and fast shifting and reliable, powerful braking from the hydraulic discs for confidence at speed in all conditions.
