Product Details
The Shimano GRX RD-RX822 12-speed rear derailleur delivers precise and reliable shifting, especially on rough terrain. It features Shimano’s Shadow Plus design combined with an integrated chain stabilizer that reduces chain slap and drops, making your ride quieter and smoother.

This smart design helps keep the chain secure and shifting smooth no matter where you ride.
The RD-RX822 comes in two versions: the SGS long cage, compatible with 10-51T cassettes for the widest gear range, and the GS medium cage, made for 10-45T cassettes. Both versions offer better ground clearance and are compatible with Shimano’s 12-speed MTB cassettes and HG 12-speed chains.
