The 2027 Cervélo S5 Ultegra Di2 is the latest evolution of one of the fastest aero road bikes ever made — a WorldTour-proven platform refined for even greater aerodynamic efficiency, a lighter chassis and an updated integrated cockpit that improves both stiffness and rider fit. Every tube profile has been optimised to cut drag while keeping the sharp, confident handling the S5 is known for.

This build pairs Shimano Ultegra Di2 12-speed electronic shifting with hydraulic disc brakes and a tubeless-ready carbon wheelset for fast, dependable performance. Clearance for tyres up to 34 mm adds comfort and grip without compromising aero performance. Finished in the Reef Blue colourway.
