Cervelo R5 Ultegra Di2 Disc Road Bike 2021
Cervelo's stiffest ever climbing bike, the R5 Ultegra Di2 Disc Road Bike is designed to help you climb with ease, and enjoy your descending to the full. The extremely lightweight All-Carbon frameset is stiffened in key areas to ensure acceleration is instant and responsive, while the bike handles predictably and is stable at high speed. The Pro Fit geometry features a low stack height to help you get in a fast, aerodynamic position as favoured by professional riders.
The Shimano Ultegra Di2 Disc groupset provides a superb electronic shifting experience, allowing you to find the right gear at the touch of a button. Stopping power is second to none too, with the hydraulic disc brakes allowing for uniform performance in any weather.
The 50mm deep Reserve 50 rims add a dash of aerodynamics to the bike's performance but are impressively light to allow for a fast climb. These wheels also really look the part on the bike, and come paired with Vittoria Corsa tubeless-ready tyres. The carbon fibre seatpost, stem and handlebar all combine to maintain a really lightweight build that absorbs road chatter for a smoother, more comfortable ride.
