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.
