CeramicSpeed OSPW Pulley Wheel Aero System Shimano 9100/9150 8000 SS/8050 SS - Coated Races Alloy Pulley Carbon Cage BLK

Experience cutting-edge cycling performance with the CeramicSpeed OSPW Pulley Wheel Aero System, specifically engineered for Shimano 9100/9150 and 8000 SS/8050 SS drivetrains. This system combines advanced aerodynamics with high-quality materials to deliver measurable improvements in speed and efficiency.

Developed through a rigorous two-year process in partnership with one of the world’s leading aerodynamicists and Drag2Zero, the OSPW Aero system underwent extensive wind tunnel testing to perfect its design. The result is a revolutionary cage structure that enhances the existing mechanically optimized design, significantly reducing drag and improving overall drivetrain performance.

• Reduces drag by an average of 40% compared to stock derailleurs, boosting your cycling efficiency and speed.
• Collaborative development with Drag2Zero ensures the highest aerodynamic standards.
• Optimized frontal area and smooth airflow control minimize turbulence behind the derailleur for superior aerodynamic gains.
• Precision 13-tooth upper and 19-tooth lower aluminum pulley wheels equipped with Grade 3 Silicon Nitride ceramic ball bearings for exceptional durability and reduced friction.
• Durable, lightweight cage constructed from polyamide reinforced with carbon fiber, balancing strength and weight.
• Coated bearing races extend service life by enhancing hardness and reducing corrosion, ensuring lasting performance.
• Exclusive compatibility with Shimano Dura-Ace 9100/9150 and Ultegra 8000-SS/8050-SS models for precise fit and function.
• Note: Not compatible with Ultegra 8000-GS or 8050-GS (medium cage) nor with clutch-equipped Ultegra RD RX800/RX805 models.
• Lifetime warranty on coated bearing CeramicSpeed products provides peace of mind and long-term reliability.

Upgrade your drivetrain with the CeramicSpeed OSPW Aero system and experience the perfect blend of aerodynamic efficiency, durability, and precision engineering. Whether you're competing or training, this pulley wheel system will help you maximize your power output and reduce wasted energy, giving you a competitive edge on every ride.
