Product Highlights


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


Shifting impeccably, this 11-speed, electronic groupset offers a professional level of performance.


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 7 Disc Road Bike 2021

Trek's third generation of Domane SL series road bikes have had a number of upgrades, making them more comfortable, more aerodynamic and more versatile. The front and rear IsoSpeed in this SL 7 now better damps vibrations, soaking up impacts over rough roads and reducing fatigue. The clearance for wider tyres - up to 38mm (35mm with mudguards) - furthers this benefit, making every ride supremely comfortable, while Endurance geometry puts you in the optimum position for longer rides and races.

Despite the incredible compliance this bike offers, it's still fast, with internal cable routing and tubes shaped to cut drag. It's perfectly complemented by the Shimano Ultegra Di2 drivetrain making shifting fast, smooth and predictable. Hydraulic disc braking brings modulated, powerful stopping that can be relied upon no matter the conditions. Bontrager's Aeolus Pro 3V full carbon wheels are strong and light with a fast engaging Rapid Drive Hub and 25mm external rim width well suited to wider road and gravel tyres. Versatility is key to the frameset's updates and the downtube now includes integrated storage. You'll be able to limit the bulk in your jersey pockets thanks to this feature - the Bontrager Integrated Tool System (BITS) stores a tube, tyre levers and CO2. You can additionally add a BITS multi-tool (purchased separately) to the storage door so you needn't leave anything important behind.
