Cervelo S5 Force AXS - 2026

The new S5 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, completing the aerodynamic system.

The new S5 is 6.3 Watts faster than its predecessor. These gains are realized primarily at the front end of the bike, but the integration of the asymmetric profiles of the seat tube and rear wheel are a significant source as well. Cervélo has long been the aerodynamic leader in the peloton, and they’re confident that the new S5 is at least 5 Watts faster than the bikes of their competitors.
