Cervelo S5 Ultegra Di2



  • Cervélo S5 carbon frame and fork
  • Shimano Ultegra Di2 12-speed electronic groupset
  • Shimano Ultegra hydraulic disc brakes
  • Reserve 63/52 carbon wheelset with Zipp ZR1 hubs

Undisputably the fastest bike of the modern era.

The Cervelo S5 Ultegra Di2 has one job—get to the line before everyone else. Under the likes of Wout van Aert, Marianne Vos, and Christophe LaPorte, the new model has already proven itself as a tool without equal. In the 2022 Tour de France, this bike propelled Wout to the highest ever Points Classification score of the modern era. At 480, Wout was some 194 points ahead of his nearest rival—tangible proof that Cervélo keeps delivering aerodynamic gains to our World Tour athletes.

The new S5 has reduced drag by 65 grams, and increased the frame’s surface area while still reducing overall weight. The deeper frame sections maximize the shapes allowed by the UCI. Meanwhile the iconic V-stem has been further refined and a new fork designed to simplify the entire front end.

What’s more, a ground-breaking new wheel design concept has been co-developed with Reserve to increase stability and reduce drag in turbulent aero conditions.

V is for Velocity

In pursuit of speed, everyone wants to try different positions to find their most aggressive fit. The S5’s iconic V-stem not only inspires confident handling at high speeds, it’s now also remarkably simple to dial in your perfect set-up. All the necessary spacers come with the bike, and there’s now only one bolt length, reducing complexity and making the system 53g lighter in the process.
