Cervelo R5 Dura-Ace Di2 Road Bike 2025
The Cervelo R5 Dura-Ace Di2 Road Bike is built for one purpose: to conquer climbs quickly. While the summit finish often steals the spotlight, the journey to get there includes numerous ascents and descents. And though races aren’t usually won on the way down, they can certainly be lost. A climbing bike that struggles in the corners is as underwhelming as a cup of decaf coffee. Now in its fourth iteration, the R5 continues to balance lightweight construction and stiffness with exceptional handling, ensuring unmatched confidence and performance on every descent.
The new R5 frame is 130 grams lighter than its predecessor, a remarkable 16% reduction from an already lightweight design. While aerodynamics weren’t the primary focus, unlike the S5 or P5 the integration of internal cable routing delivers a 25 gram drag reduction, enhancing its overall efficiency.
