The 2025 Cervélo S5 Dura-Ace Di2 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.
