Cervélo S5 Ultegra Di2 2025: the new fastest aero bike ever

If you are a cyclist who focuses entirely on speed, aerodynamics, and precision, the new Cervélo S5 Ultegra Di2 is the racing bike you have been waiting for. After years of research, wind tunnel testing, and winning performances in the World Tour, Cervélo has launched a completely updated version of its iconic aero bike, taking the concept of efficiency to an even higher level.


Completely renewed design: faster, lighter, more aggressive

The first thing that catches the eye is the new integrated HB19 monoblock cockpit with an evolved V design. Not only aesthetically futuristic, but also incredibly effective: thanks to the “Plus-Four” concept, the upper part of the handlebar is 4 cm narrower than the lower grip, promoting a more aerodynamic position without sacrificing stability.

The fork and head tube have been completely redesigned to optimize airflow and improve aerodynamic penetration. The result? The new S5 is over 6 Watts faster than the previous version and 124 grams lighter, without compromising stiffness and handling.


Reserve 57 wheels|64: aerodynamics even in crosswinds

One of the strengths of this new model is the introduction of the Reserve 57|64 Turbulent Aero wheels, developed in collaboration between Cervélo and Reserve. The most innovative aspect? The shape and asymmetry of the wheels perfectly integrate with the frame, optimizing airflow even in crosswind conditions.

This means greater stability, speed, and safety, even on the most demanding rides or races with variable weather conditions.


Shimano Ultegra Di2 12v: smooth and precise electronic transmission

The mechanical heart of the S5 is the highly reliable Shimano Ultegra Di2 R8100 12-speed groupset, which guarantees instant, silent, and responsive electronic shifting. The setup is completed by:

  • Power meter 4iiii Precision Pro GEN3+ dual side

  • Shimano Ultegra disc brakes with CL800 rotors

  • Tires Vittoria Corsa Pro TLR 700x29c, tubeless ready

  • Ultegra 52/36T crankset for optimal power at high speeds


Who is the new Cervélo S5 designed for?

The Cervélo S5 Ultegra Di2 is the perfect racing bike for competitive cyclists, athletes, triathletes, and advanced amateurs who want the best in terms of aerodynamics, responsiveness, and style. It is the ideal weapon for road races, criteriums, gran fondos, and for those who love fast, technical, and modern cycling.

If you really want to take your road performance to the next level, the new Cervélo S5 Ultegra Di2 is the right choice. Speed, lightness, and technology merge in a race machine born to win.
