Shimano GRX RD-RX822 Cambio trasero GS 12-Vel

Better chain protection and quieter shifting in gravel use.

With its integrated chain stabiliser, the SHIMANO GRX rear derailleur ensures quieter shifting and safer chain management in rough terrain. The RD-RX822-GS is compatible with SHIMANO 12-speed MTB cassettes 10-41Z, so you'll never run out of gears even on the steepest forest highway and the steepest single-trail climb in the high mountains.
