Cervelo R5 Dura-Ace Di2 Bike Info
The Cervélo R5 Dura-Ace Di2 Bike is built for climbers who demand the lightest, stiffest, and most responsive ride. Engineered with Cervélo’s advanced carbon layup, this bike offers explosive acceleration on steep gradients while maintaining stability and control on technical descents.
Weighing in at just under 6 kg in a complete build, the R5 is a featherweight performer without sacrificing stiffness or durability. Its geometry mirrors Cervélo’s pro-level aero road platforms, providing a seamless fit and handling experience for elite racers. With Shimano’s flagship Dura-Ace Di2 drivetrain, every shift is lightning-fast and precise, ensuring maximum efficiency on race day.
Every detail of the R5 is designed with performance in mind, from the integrated HB18 cockpit that reduces drag and saves weight, to the Reserve carbon wheels that balance lightweight climbing efficiency with stable aerodynamics. Wider tire clearance up to 29 mm enhances comfort and grip, while the refined bottom-bracket drop improves cornering stability.
