Cervelo R5 Frameset 2026

Description

Cervelo R5 Carbon Frameset 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 all-new R5 frameset weighs a mere 949 grams including the fork.

Lightweight Cervelo R5 Frame

In size 56, the R5 weighs 5.97kg, 900 grams below the UCI minimum. The frame is 651 grams, the fork 298 grams, and refinements to every component cut a total of 326 grams across the bike.

Cervelo Race-Ready Fit Geometry

Handling geometry is largely unchanged, aside from a minor bottom bracket adjustment for 29mm tyres. Fit geometry now matches the S5, keeping riders in an optimal position for fast group rides.

Cervelo One-Piece Handlebar and Stem

The HB18 handlebar and stem drop 150 grams and improve aerodynamics by two Watts. Drawing on S5 insights, it delivers comfort, stiffness, and speed, ideal for long days and sprint finishes. All sizes remain UCI-legal.
