Enhanced chain security and quieter shifting for gravel riding

With its integrated chain stabilizer, the SHIMANO GRX rear derailleur delivers quieter shifting and more secure chain management in rough terrain. The RD-RX822-SGS is compatible with 10-51T, 12-speed SHIMANO MTB cassettes, meaning you’ll never run out of gears even on the steepest jeep road or high mountain singletrack ascent. And the chain tensioner has an ON/OFF switch for easy wheel removal.
