Cervélo S5 Red AXS 2026 Road Bike

The Cervélo S5 is the ultimate benchmark for speed and aerodynamic efficiency, with impressive results to prove it. From Wout van Aert’s legendary green jersey victory to Simon Yates in the maglia rosa – the S5’s iconic V-stem and bayonet fork are ubiquitous in the professional peloton. The new generation builds on that success and is now even faster than ever.

With a gain of over 6 watts in efficiency, a weight reduction of 124 grams, and the same balanced handling, the S5 stays true to its roots but elevates performance to a higher level. The biggest improvements are found at the front of the bike, where a deeper fork and head tube ensure unprecedented aerodynamics.

Together with the completely redesigned one-piece stem and cockpit, the S5 forms a perfect whole. In collaboration with Reserve, the new Reserve 57|64 Turbulent Aero wheelset was developed – specially tuned to the frame – with which Cervélo has created an aerodynamic system that exudes pure speed.
