The S-Series is designed to be an aerodynamic integrated system incorporating the rider, frame, and components. Frame tube shapes and design elements work together to manipulate and smooth the airflow over the bike and rider. The result: you go faster.
Stiffness in critical parts of the frame is essential for calm and precise handling and pedaling efficiency. Most aerodynamic bikes have to trade off aerodynamics for stiffness, but we worked hard to ensure the S-Series frames are stiff, while not sacrificing aerodynamic performance.
