Cervelo R-Series Ultegra Disc Road Bike 2021
Ride with agility and speed, whether dancing up hills or cruising down the other side on the Cervelo R-Series Ultegra Disc Road Bike. By using Squoval Max tubing on the all-carbon frameset, Cervelo have managed to maximise the stiffness to weight ratio for a ride that accelerates with ease while providing enough compliance for all-day comfort.
The full Shimano R8020 11-speed groupset boasts hydraulic disc braking for powerful and modulated stopping, as well as slick shifting from the superb derailleurs. The mid-compact chainset is paired with an 11-30t cassette to provide the gearing ratio you need for steep climbs as well as long flat sections and town sign sprints. Rolling on a set of DT Swiss P1800 Spline wheels, the 32mm deep aluminium rims deliver durability and a keen aerodynamic edge too.
