OSPW for Campagnolo 11-speed EPS & Mechanical

The CeramicSpeed Oversized Pulley Wheel (OSPW) System for Campagnolo 11-speed is the ultimate performance upgrade for riders who demand the legendary smoothness of Italian engineering paired with the world's most efficient drivetrain technology. Designed to accommodate both electronic (EPS) and mechanical setups, this system replaces the standard 11-tooth pulleys with a 13-tooth upper and 19-tooth lower combination. This radical increase in size reduces chain articulation angles and pulley rotation speed, resulting in a 40% reduction in friction compared to stock Campagnolo components. Whether you are climbing the Dolomites or sprinting for a local segment, this OSPW system ensures that your Campagnolo drivetrain operates at its absolute peak efficiency.
