Description
Description
The CeramicSpeed OSPW RS 5-Spoke for Shimano 9250/8150 is the upgrade for demanding cyclists who want to get the most out of their performance. This advanced Oversized Pulley Wheel System (OSPW) reduces friction in the drivetrain, improves efficiency, and gives your bike a high-end, aerodynamic look. Designed for use with Shimano's 12-speed Di2 Dura-Ace R9250 and Ultegra R8150 groupsets.
Optimized for speed and durability
The combination of carbon/PA-based 5-spoke derailleur pulleys and an ultralight aluminum cage creates a stiff and durable construction with a refined design. Thanks to the industry-leading CeramicSpeed bearings, you'll experience up to 30-60% less friction compared to standard pulleys.
Aerodynamics meets efficiency
The new RS (Racing Series) 5-Spoke pulley wheels are not only lighter but also aerodynamically optimized for top performance. Ideal for both competitive riders and serious amateurs who value efficiency and aesthetics.
