Shimano GRX RD-RX820 12-Speed Rear Derailleur Max 51T

With its integrated chain stabilizer, the Shimano GRX RD-RX820 12-Speed Rear Derailleur Max 51T 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.
