Product Highlights


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


A meticulous layup allows this carbon material to infuse stiffness and compliance into the frame.


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 SLR 7 Disc Road Bike 2021

With race-proven performance, the Trek Domane SLR 7 Disc Road Bike brings speed, comfort and versatility in this third-generation design. Adjustable IsoSpeed damps the harshest fatigue-inducing surfaces, while wider tyres ensure you'll roller faster over rough roads. The 700 Series OCLV carbon construction keeps stiffness high and Trek's Endurance geometry optimises your position for longer rides and races - it's still fast but slightly more relaxed. Aerodynamics were also considered in the tube shapes so, together with the sleek internal cable routing, drag is significantly reduced.

Ultegra Di2 is Shimano's second-tier electronic groupset and there's just a very small weight penalty over the flagship Dura-Ace model. Shifting is smooth at just a light touch of the lever, while hydraulic disc braking adds control and inspires confidence at speed. On longer rides, you'll appreciate the option to store tools and gear in the downtube in a dedicated internal storage compartment.
