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, evolving the front end, and going on a bit of a diet, making it an even more potent partner for the fastest riders in the world. 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.
Cervélo and Reserve co-developed the new Reserve 57|64 Turbulent Aero wheels specifically for use in the S5 frame. The offset of the wheels perfectly matches the asymmetry of the S5 seat tube,
and they tuck right into the wheel cut outs. This ensures that air flows smoothly over the entire bike, and Reserve’s Turbulent Aero approach makes them incredibly stable, even in crosswinds.
