Greater chain stability and quieter gear shifts for Gravel

Thanks to the integrated chain stabilizer, the SHIMANO GRX derailleur offers quieter gear shifts and safer chain management on rough terrain. The chain tensioner features an ON/OFF switch to facilitate wheel removal.

The RD-RX822-GS derailleur is compatible with SHIMANO MTB 10-45T 12-speed cassettes. The RD-RX822-SGS derailleur is compatible with SHIMANO MTB 10-51T 12-speed cassettes, so you'll never run out of gears even on the steepest climbs of gravel roads or high mountain singletracks.
