Shimano Grx Shadow+ RD-RX822 Rear Derailleur

SHIMANO GRX RD-RX822 REAR DERAILLEUR - 12-SPEED SHADOW+ CONTROL FOR GRAVEL AND ADVENTURE RIDING


Built to conquer rough gravel, steep climbs, and long adventures, the SHIMANO GRX RD-RX822 12-Speed Rear Derailleur delivers smooth, quiet, and reliable shifting for 1x gravel drivetrains paired with mountain bike cassettes. Designed with SHIMANO's trusted SHADOW+ chain stabilizer technology, it ensures optimal chain security and silent operation even over harsh terrain - giving you precise control wherever the ride takes you.



KEY FEATURES

Developed specifically for gravel riding, the RD-RX822 features a long SGS cage with 41-tooth capacity, perfectly matched to wide-range 10-51T MTB cassettes. A shorter GS cage option supports 10-45T setups, and both cages are interchangeable - allowing easy adaptability without needing a full derailleur replacement. The SHADOW+ stabilizer reduces chain slap and drop, with an on/off switch for convenience when riding smoother surfaces or removing the rear wheel. High-quality bearings in the guide and tension pulleys ensure consistently smooth performance, while the lightweight aluminium construction keeps overall weight to a minimum.


WHY TO CHOOSE

Choose the GRX RD-RX822 if you want dependable, quiet, and versatile shifting performance across diverse gravel terrain. Its replaceable cage design, stable SHADOW+ system, and mountain cassette compatibility make it the ideal upgrade for riders seeking maximum control and minimal maintenance on their 1x12 setup.


INTENDED USERS

Perfect for gravel, adventure, and bikepacking cyclists using 1x12 drivetrains who demand wide-range gearing, quiet precision, and durable performance over mixed or challenging terrain.
