Cervélo S5 Dura-Ace Di2 (2026)

The 2026 Cervélo S5 Dura-Ace Di2 represents the pinnacle of aerodynamic road bike performance. Refined to be 6 watts faster and 124 grams lighter than the previous generation, the latest S5 pushes the boundaries of speed with every surface engineered for maximum aerodynamic efficiency and real-world race performance.

From its deeper aero tube profiles to the redesigned bayonet fork and refined V-stem cockpit, the S5 is built to slice through the wind while maintaining exceptional stability at high speeds. Developed in partnership with Reserve, the bike is equipped with a purpose-built 57 mm front and 64 mm rear Turbulent Aero wheelset paired with DT Swiss 180 hubs for maximum aerodynamic advantage and rolling efficiency.

Shimano’s flagship Dura-Ace Di2 12-speed electronic drivetrain delivers lightning-fast shifting and flawless reliability, while the integrated dual-sided power meter provides precise performance data for training and racing. A CeramicSpeed BBright bottom bracket further reduces friction for uncompromising efficiency.

Despite its pure race focus, the S5 remains practical for modern riders with clearance for tyres up to 34 mm, integrated storage solutions and complete cockpit integration. The result is a World Tour-level aero race bike designed to perform at the highest level.
