Aerodynamic Precision

The Cervélo S5 is more than just an aero road bike; it is a meticulously tuned aerodynamic system. The synergy between the Reserve 57/64 wheels and the frame's asymmetric seat tube ensures that airflow remains attached to the bike longer, reducing drag in real-world "turbulent" conditions. With a 54/40T chainring setup and pro-level stability, this bike is built for maximum velocity and podium finishes.
