Performance Built for gravel, the GRX RD-RX820 delivers silent, secure 12-speed shifting on rough and mixed terrain. Shimano's Shadow RD+ design with an adjustable chain stabiliser prevents chain slap and drops, and an ON/OFF stabiliser switch lets you match the setup to the terrain. The low-profile body reduces the risk of crash damage. Options Available in 36T, 46T and 51T maximum-sprocket versions to suit different cassette ranges - the wider-capacity options support mullet and wide-range setups. Select the version that matches your cassette.
