For the bell lap of a criterium. Or a sprint distance triathlon. For the attack, the chase, the thrill of speed. Every aspect of the Propel Advanced Pro is engineered as a complete system to deliver unbeatable aero road performance. Extensive CFD analysis and dynamic wind-tunnel testing was used to optimize every frame tube and angle in a process called AeroSystem Shaping technology. The frame is then handcrafted using Advanced-grade composite material to produce a bike that’s both stiff and light, with a sharp, responsive ride quality. Purpose-built aero road technologies, including SpeedControl SL brakes and a Vector seatpost further enhance this well-rounded, wind-slicing performer.
