CeramicSpeed OSPW X for Shimano GRX 2×12 Derailleur Cage System
The CeramicSpeed OSPW X (Oversized Pulley Wheel System) has been specifically developed for Shimano GRX 820 series 2×12-speed systems to provide ultimate efficiency and durability in both road and demanding gravel conditions.
The system features a 13T upper and a 19T lower pulley wheel, which reduce chain wrap angle and friction. This ensures smoother shifting and saves energy with every pedal stroke. Hand-built ceramic bearings offer minimal resistance and up to 500% better durability compared to standard bearings.
Thanks to the carbon fiber reinforced cage and specially designed pulleys, the OSPW X is capable of withstanding vibration and contamination while maintaining CeramicSpeed’s signature ultra-low friction coefficient—35-40% lower than traditional cage systems.
- Discipline: Gravel and Cyclocross
- Compatibility: Shimano GRX RD-RX820 / RD-RX825 2×12. For 1x systems, this cage can be used with cassettes up to a 36T largest sprocket.
- Note: Only the H (high) spring tension hole should be used with the RX825 Di2 derailleur.
- Pulleys: 13T upper and 19T lower pulley wheels
- Material: Carbon fiber reinforced polymer cage and aluminum pulleys
- Bearings: CeramicSpeed ceramic bearings (hand-built)
