R5 Ultegra Di2
The Cervélo R5 Ultegra Di2 is the ultimate climbing specialist, engineered to be 130g lighter than its predecessor while maintaining the World Tour-winning stiffness and handling stability. It balances a classic "double diamond" silhouette with modern integrated tech, creating a featherweight race machine that excels on the steepest gradients and most technical descents.

KEY FEATURES

Why we like the Cervélo R5 Ultegra Di2
Supreme Climbing Prowess
We love how the 16% frame weight reduction and 13% bottom bracket stiffness increase make this bike feel incredibly reactive and "alive" as soon as the road tilts upward.
Refined Ride Quality
The combination of a D-shaped carbon seatpost and compliant seat stays successfully dampens road vibrations, keeping you fresh during high-altitude epic rides
Clean Aero Integration
The HB18 one-piece carbon cockpit elegantly hides all cables, saving 25g of drag without the mechanical complexity often found in pure aero bikes
