Shimano GRX RD-RX822 12-Speed Rear Derailleur
Product Details
The Shimano GRX RD-RX822 12-speed rear derailleur is designed for gravel and mixed-terrain riding, delivering precise shifting performance and enhanced chain stability in demanding off-road conditions. Built on Shimano’s Shadow RD+ clutch system, it helps reduce chain slap and improves chain retention for a quieter, more controlled ride over rough surfaces.
The derailleur features an ON/OFF switch for the clutch mechanism, allowing riders to easily disengage chain tension when removing the wheel or performing maintenance. This improves practicality without compromising drivetrain stability during riding.
The RD-RX822 is available in different cage configurations to support a range of cassette sizes, allowing riders to tailor gearing for climbing ability or wider terrain versatility depending on setup.
Compatible with Shimano 12-speed HG chains, the RD-RX822 is engineered for durability, smooth shifting, and reliable performance in gravel and adventure riding environments.
