Product Details
Cervelo R5 Ultegra Di2 Carbon Road Bike 2026
The Cervelo R5 Road Bike is legendary. From the limits-shattering R5CA to Wout van Aert’s win on Mont Ventoux, the R5 has defined Cervelo for over two decades. The latest R5 frame weighs just 949 grams and is stiff enough to perform at the very highest level, as proven by Pauline Ferrand-Prévot at this summer’s Tour de France Femmes.
Lightweight Cervelo R5 Frame
In size 56, the R5 tips the scales at just 651 grams for the frame and 298 grams for the fork, delivering the perfect balance of lightness and strength.
Cervelo Race-Ready Fit Geometry
Handling geometry remains almost unchanged, with only a minor bottom bracket adjustment to accommodate 29mm tyres. Fit geometry now matches the S5, ensuring an optimal riding position for fast group rides and racing.
Cervelo One-Piece Handlebar and Stem
The HB18 bar and stem save 150 grams and improve aerodynamics by two Watts. Inspired by the S5, this integrated design provides comfort, stiffness, and speed, making it ideal for long climbs and sprint finishes. All bar sizes remain fully UCI-legal.

Q & A
1 question answered
Is it possible to get the bike built with a 'normal' crank rather than a 4iiii power meter? I have dual sided power pedals that I would want to use, so have no need for a crank-based power meter.
Hi there, Please contact the Sales team and they will help with this, Many thanks Joe W
