The CeramicSpeed OSPW X for Shimano GRX RX-820 2x12 is a high-performance component system designed specifically for gravel and cyclocross disciplines. Proven in demanding races like Paris-Roubaix and Strade Bianche, this pulley wheel system enhances your drivetrain with exceptional durability and significantly reduced friction. Built to meet the rigorous demands of off-road riding, it offers riders a smooth, efficient transmission that extends component life and maximizes power transfer.
This system features a 13-tooth upper and 19-tooth lower pulley wheel, housed in a custom molded carbon fibre cage that balances lightweight design with robust durability. The four different spring tension settings allow you to fine-tune the system to your specific riding conditions, ensuring optimal performance whether you’re tackling rough terrain or fast gravel stretches. Compatible with Shimano’s 2x specific RX820 and RX825 derailleurs, it also supports 1x setups with a maximum 36T cassette.
With the CeramicSpeed OSPW System, you will experience a remarkable 35-40% reduction in friction compared to stock pulley configurations, translating into smoother shifting and increased drivetrain efficiency. The package includes CeramicSpeed oil for pulley wheel bearings, ensuring long-lasting lubrication and maintenance ease. Note that only the high (H) spring tension setting should be used with the RX 825 Di2 derailleur to guarantee optimal function.
Can I use the CeramicSpeed OSPW X with Shimano GRX RX825 Di2?
Yes, it is compatible, but you must use only the high (H) spring tension hole for optimal performance with the RX 825 Di2 derailleur.
Is this system compatible with 1x drivetrains?
Yes, but only with cassette sizes up to 36T. For larger cassettes, this system is not recommended.
