Cervelo S5 Shimano Ultegra Di2 Road Bike 2026
The Cervélo S5 Road Bike is a WorldTour-proven aero race bike engineered for riders chasing maximum speed and efficiency. The latest S5 builds on Cervélo’s aerodynamic legacy with a redesigned all-carbon frameset, deeper fork and head tube profiles, and an integrated HB19 carbon cockpit, delivering a claimed 6.3-watt aerodynamic improvement while reducing system weight by 124 grams compared with its predecessor.
Equipped with Shimano Ultegra Di2 12-speed electronic shifting, Reserve 57|64 Turbulent Aero carbon wheels with DT Swiss 240 hubs, and Vittoria Corsa Pro TLR 700x29c tyres, the S5 delivers a premium race-ready package. Its distinctive Bayonet fork, asymmetric aerodynamic integration, and Plus-Four cockpit concept combine outright speed with confident handling and stability for racing, fast group rides, and high-performance road cycling.
FEATURES
Race-Proven Aero Performance: The latest S5 delivers a claimed 6.3-watt aerodynamic improvement over its predecessor, with extensive optimisation focused around the front end and rear-wheel integration.
124g Lighter Design: Refined carbon layup and hardware reduce overall system weight by 124 grams despite increased aerodynamic surface area.
