Take your gravel riding adventures to the next level with the Shimano GRX RX820 rear derailleur. The Shadow+ switch and relatively high spring tension of the cage keep the chain tension of the Shimano GRX RX820 derailleur at an optimal level for off-road terrain. This makes sure that shifting gears is quick and quiet. Decrease your chances of chain noise and of your chain falling off the front chainring, even on the steepest slopes and bumpiest singletrack descents. The Shimano GRX RX820 rear derailleur is compatible with 10-51T 12 speed Shimano MTB cassettes. Shift into the right gear, whatever the conditions.
