The Shimano GRX RD-RX822 rear derailleur brings 1x shifting options to Shimano gravel. The GS derailleur cage is compatible with up to 45T cassettes, while the SGS can accommodate up to 51T so you can fit a wide range if it suits your riding style and terrain. The RD-RX822 is 1x specific and uses Shimano's Shadow Plus design for optimal chain retention. Accommodating a wide range of gears in a 1x drivetrain makes for a fast setup when you need it while still being more than capable in those technical sections where control is key.
