ON THE ATTACK, IN A SPRINT, OR CORNERING AT SPEED. EFFICIENCY MEETS TOTAL CONTROL IN THIS WIND-SLICING MISSILE. ENGINEERED WITH AEROSYSTEM SHAPING TECHNOLOGY, AN INTEGRATED WHEELSYSTEM, AND DISC BRAKES THAT ARE BOTH POWERFUL AND AERODYNAMIC, IT GETS UP TO SPEED AND STAYS THERE WITH MINIMAL RESISTANCE.
This aero road bike minimises drag so you can accelerate and sprint faster. Engineered with AeroSystem Shaping technology and Advanced-grade composite material, it delivers proven aero performance and one of the lightest frames in its category. The Propel Advanced Disc also comes with an integrated WheelSystem, flat-mount disc-brake calipers and thru-axles for added wheel stiffness and streamlined performance. The lightweight, easily adjustable Vector composite seatpost further minimizes drag. It all adds up to a race-ready machine that leaves the competition behind.
KEY PERFORMANCE FACTORS:
AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimises aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SL Aero cockpit help produce the best overall aero performance.
Integrated disc brakes deliver powerful stopping power and modulation for added control in variable weather. Thru-axles boost stiffness and improve overall handling, and an integrated WheelSystem with a 65mm rear rim and shallower 42mm front rim optimises aerodynamics and control.
Advanced-grade composite frameset features high-performance materials and modern manufacturing processes for optimised stiffness and the lowest weight in its category.
