The Shimano GRX RD-RX822 is a 12-speed rear derailleur engineered for gravel and mixed-terrain riding.
Its integrated Shadow Plus chain stabilizer reduces bounce and noise on rough surfaces, delivering smooth, precise shifts when you need them most. The low-profile design combines lightweight cold-forged aluminium construction with exceptional durability. Compatible with 12-speed Hyperglide+ chains, it supports cassettes up to 10-51T, making it ideal for single-chainring setups that demand versatile gearing across unpredictable terrain.
