CeramicSpeed OSPW X for Shimano GRX 2x12

This OSPW system with 13-tooth upper pulley and 19-tooth lower pulley has proven itself in races such as Paris-Roubaix, Strade Bianche, and the Cyclocross World Cups. The system is designed for Gravel and cyclocross disciplines and meets the requirements for durability, low friction resistance, and longevity.

• Four spring tension settings for individual setup depending on riding conditions
• Handcrafted OSPW cage made from custom carbon fibre composite for low weight and high durability
• CeramicSpeed OSPW systems reduce friction resistance by 35–40% compared to the stock pulley
• Compatible with the 2X-specific derailleurs RX820 and RX825

When used as a 1x system, a maximum cassette of 36T must be observed. Note: For the RX825 Di2 derailleur, only the spring hole H (High) may be used.
