Shimano GRX RX822 Rear Derailleur SGS Info
The Shimano GRX RX822 Rear Derailleur SGS is built for the demands of gravel riding — where terrain shifts constantly and your drivetrain needs to keep up without complaint. As part of Shimano's 12-speed GRX 820 groupset, the RX822 handles a wide 10-51T cassette range, giving you the low gearing to grind steep unpaved climbs and enough top-end for fast tarmac connectors between them.
The Shadow RD+ mechanism keeps the derailleur quiet and controlled on rough ground. Its integrated chain stabilizer — designed to reduce chain slap and prevent drops on technical sections — can be switched off when conditions don't require it, so you're not adding unnecessary tension on smoother surfaces. It's a practical feature that earns its place on longer mixed-terrain rides where the trail can go from chunder to hardpack without warning.
