Cervélo S5 Frameset (2026)

The aero benchmark, now even faster.
The 2026 Cervélo S5 frameset drops 6 watts of drag and 124 g of weight versus the previous generation, sharpening the bike that wins WorldTour sprints. Deeper aero profiles, the Bayonet S5 fork and V-stem deliver free speed without dulling the S5’s precise, stable handling. Developed alongside Reserve’s 57|64 Turbulent Aero wheels, the platform is ready to turn every watt into motion.
