Product Highlights


Lightweight and stiff, OCLV 500 carbon soaks up road vibrations and provides a comfortable ride.


This 11-speed gear configuration rivals top-tier groupsets with its smooth and crisp gear shifts.


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 5 Disc Road Bike 2021 

Suited to the endurance rider looking for a perfect blend of performance and practicality, the Trek Domane SL 5 Disc Road Bike is fast, compliant and has additional storage inside the downtube. Aerodynamics have been considered in the tube shaping and, together with the benefit of internally routed cables, you can put in faster times for the same effort. Both front and rear IsoSpeed are now even more effective and with space for tyres up to 38mm, will ensure the roughest roads feel smoother with less of the fatiguing shocks being transferred into your body.

Shimano's 105 components offer reliability and performance. The hydraulic disc brakes make for excellent stopping power no matter the conditions, plus bring improved control at speed, while the drivetrain has a compact chainset coupled with an 11-34 cassette so you can make light work of the longest climbs.
