The Cervelo S5 Frameset 2026 is Cervélo's WorldTour-proven aero race frameset, the platform behind Team Visma | Lease a Bike's Grand Tour success. It gives you the latest-generation S5 chassis to build up with your choice of drivetrain, wheels and finishing kit, offered here in TVL Replica, Lupine, Carnelian and Five Black.
Over 6 watts faster and 124 g lighter than its predecessor, the new S5 focuses its gains at the front end with deeper fork legs and head tube, and an all-new HB19 one-piece handlebar/stem that evolves the iconic V-stem. The frameset includes the all-carbon Bayonet S5 fork, FSA SL IS2 headset, Cervélo aero thru axles, HB19 cockpit and SP34 carbon seatpost.
FEATURES
- WorldTour Aero Platform: The S5 is Cervélo's flagship aero race frame, proven at the front of the professional peloton.
- 6.3 Watts Faster: Deeper fork legs and head tube plus asymmetric seat tube and rear wheel integration deliver a claimed 6.3-watt gain over the previous S5.
- 124 g Lighter: Optimised carbon layup and hardware make the system 124 g lighter than its predecessor despite the larger aero profiles.
- Bayonet S5 Fork: Iconic all-carbon Bayonet fork forms part of the aero system and gives precise front-end control.
- HB19 One-Piece Cockpit: Carbon handlebar/stem builds on the V-stem concept for a clean, fully integrated front end.
- Plus-Four Bar Shape: Hoods are 4 cm narrower than the drops for a faster position on the hoods and stability in the drops; all sizes are UCI-legal.
- Built Around 29 mm Tyres: Geometry and clearance suit modern 29 mm race tyres, with room for up to 34 mm.
- Reserve 57|64 Optimised: Frame co-developed with Reserve so the 57|64 wheels' asymmetric rear profile matches the seat tube.
- Proven Handling: Retains the stability, poise and sharp handling the S5 is known for.
