2026 Cervelo S5 Shimano Ultegra Di2 Carbon Aero Road Bike

Pro-Level Aero Features

• Redesigned TrueAero™ Frame: Advanced tube shaping and a Bayonet S5 fork significantly reduce drag, especially in high yaw wind conditions.

• Reserve 57/64 Turbulent Aero Wheels: Co-developed to match the frame perfectly, featuring premium DT Swiss 180 DICUT hubs for minimal rolling resistance.
• HB19 Carbon One-Piece Cockpit: The iconic V-stem evolved into a one-piece design with a 4cm flare—narrower at the hoods for aerodynamics and wider at the drops for control.
