Maximize your wattage and redefine your time trial or triathlon splits. The OSPW Aero ALPHA system takes the fastest proven aerodynamic derailleur cage and elevates it with cutting-edge engineering. By effectively sheltering the rear derailleur, it cuts aerodynamic drag by a staggering 60% and friction by up to 40% compared to stock configurations, translating every pedal stroke into raw forward momentum.
Experience unparalleled shifting silence and durability. Integrated with Patented ADR technology, the bearing is fully shielded from debris, ensuring long-lasting, frictionless rotation regardless of riding conditions. The revolutionary ALPHA solid disc pulleys feature a composite tooth profile, heavily neutralizing chain noise and vibration. Engineered exclusively for SRAM Red and Force AXS, this is the definitive upgrade for riders refusing to compromise on speed or performance.
