Cervélo S5 Dura-Ace DI2 black 2025

Cervélo S5 Dura-Ace DI2 Black 12-Speed Carbon Aero Bike 2025

The 2025 Cervélo S5 Dura-Ace DI2 black is built for one thing: speed. The bike of choice for sprinters and World Tour riders, it notably supported Wout van Aert in his domination of the points classification at the 2022 Tour de France. With its redesigned frame to maximize aerodynamics, optimized integration, and compatibility with wider wheels, it offers an undeniable advantage over the competition. Stiffer, lighter, and faster, the S5 was designed to excel on all terrains.

New UCI aerodynamic design regulations have allowed Cervélo to further refine tube profiles to reduce drag and improve speed. The frame adopts deeper sections in the head tube and bottom bracket, while the fork has been redesigned for smoother integration. The bike also features Reserve 52/63 wheels, developed in collaboration with Cervélo to deliver optimal aerodynamic performance.

In addition to its cutting-edge performance, the S5 boasts improved ergonomics. Its cockpit has been redesigned with more comfortable handlebars and a simplified "V" stem system, making position adjustments easier. It also comes with a reduced-setback seatpost to accommodate modern rider preferences. In its quest for perfection, Cervélo has also removed compatibility with mechanical groupsets for optimized electronic integration.
