Cervélo S5 Ultegra Di2 Road Bike 2025
The Cervélo S5, built for speed, has proven its dominance with cyclists like Wout van Aert, Marianne Vos, and Christophe LaPorte. In the 2022 Tour de France, Wout set a record with a Points Classification score of 480, beating his closest rival by 194 points, underscoring the S5’s superior performance. The new S5 reduces drag by 65 grams, increases frame surface area, and decreases overall weight. Optimized frame sections comply with UCI regulations, while a refined V-stem and redesigned fork streamline the front end. Additionally, a groundbreaking wheel design co-developed with Reserve enhances stability and reduces drag in turbulent conditions.
