Description:
The 2027 Cervélo S5 Dura-Ace Di2 is an elite, aerodynamic carbon road bike featuring Cervélo frame updates, a Shimano Dura-Ace Di2 12-speed groupset, and Reserve 57|64 carbon wheels. It is built for pure speed, making it a top choice for WorldTour sprinters and high-speed road racing.
Designed For:
The Cervélo S5 Dura-Ace Di2 is designed for pure speed, elite-level road racing, and WorldTour sprinting. It targets riders wanting to get to the finish line first through maximum aerodynamic efficiency and intense lateral stiffness.
Highlights:
The S5 is a sport-wide benchmark for speed and aerodynamic efficiency—with the race results to back it up. From Wout van Aert winning the Green Jersey by the biggest margin of victory in modern history, to Simon Yates riding himself into the maglia rosa, S5’s iconic V-stem and bayonet fork are a fixture at the front of the professional peloton. The new S5 builds on that legacy of speed by getting even faster.
The new bike is over 6 Watts faster than its predecessor, 124 grams lighter, and retains the handling, poise, and stability that riders everywhere love. The biggest changes are at the front of the bike, where the most significant aerodynamic performance comes from. The fork legs and head tube got quite a bit deeper, and the all-new, one-piece handlebar/stem builds on the original V-stem concept—and gets even faster.
Despite an increase in surface area, the new S5 is 124 grams lighter than its predecessor. While the increase in fork and head tube depth added weight, we optimized the layup and hardware to make the system lighter.
The new Reserve 57|64 wheelset was co-developed by Reserve and Cervélo, and designed for use in the new S5. The rear wheel’s asymmetry matches the seat tube, ensuring air flows smoothly over both. The new wheelset is 3 Watts faster than the 52|63 wheels, and weighs the same.
