Experience unmatched performance with the CeramicSpeed OSPW RS Alpha Pulley Wheel System designed specifically for Shimano Dura-Ace 9250 and Ultegra 8150 rear derailleurs. Featuring a sleek, modern, and angular design, the OSPW RS Alpha system seamlessly integrates with the latest bike aesthetics and groupset trends, elevating both form and functionality. This innovative system is engineered to deliver a premium ride experience by combining cutting-edge technology and enhanced durability.
The injection molded carbon fiber reinforced PA cage provides superior strength and longevity, ensuring your drivetrain remains reliable under demanding conditions. The Alpha disc pulleys incorporate a composite narrow-wide tooth profile that effectively prevents debris accumulation between the spokes — keeping your drivetrain cleaner and shifting smoother. With 13-tooth upper and 19-tooth lower pulley wheels, each equipped with ADR bearing protection, the bearings are fully enclosed, maximizing lifespan and performance.
At the core of the OSPW RS Alpha system are grade 3 Silicon Nitride ball bearings, which outperform standard steel bearings by being 400% smoother, 128% harder, and 58% lighter. This translates into significantly reduced friction and enhanced energy transfer, allowing you to ride faster and more efficiently. Additionally, the system offers 4 customizable spring tension settings, enabling precise tuning for your preferred shifting feel and optimal drivetrain performance.
Compatible exclusively with Shimano Road Dura-Ace R9250 and Ultegra R8150 12-speed rear derailleurs, this pulley wheel system is a direct upgrade that guarantees compatibility and maximizes drivetrain efficiency.
