This 13-tooth upper and 19-tooth lower OSPW system has been platform-proven in races like Paris Roubaix, Strada Bianche, and CX World Cup. The system is built for gravel and cyclocross disciplines, meeting demands for durability, low friction, and long lifespan. Four spring tension settings allow for tailored adjustment based on riding conditions, and the handcrafted OSPW system offers a custom-molded carbon fiber cage for low weight and durability. The CeramicSpeed OSPW system reduces friction by 35-40% compared to a pulley wheel configuration.



Compatible with 2X-specific RX820 and RX825 derailleurs. If using 1x, a maximum 36T cassette can be used.



Note: With the RX825 Di2 derailleur, only the H (High spring tension) hole should be used.



In the box:

Complete OSPW X for Shimano GRX RX-820 2x12 system CeramicSpeed Oil for pulley wheel bearings, 15 ml. dropper bottle

CeramicSpeed is a Danish brand that specializes in high-performance ceramic bearings and drive components for various industries including cycling, automotive and industrial applications.

He began experimenting with ceramic materials, which are known for their low friction and high wear resistance. After years of research and development, CeramicSpeed was born.
