Shimano GRX RX812 Rear Derailleur 1x11-speed
Shimano GRX is a gravel specific components group with gravel optimized gearing options and rugged reliability. Not a modified set of road components, it was designed from the ground up as a gravel specific groupset. GRX eliminates any excuses urging you to try that rough sidetrack or ride that little bit longer. It offers you the option to Explore Beyond!
The integrated chain stabilizer mechanism on the new SHIMANO GRX derailleur makes for a quieter ride while delivering precise, fast and reliable shifting on all types of terrain. For rides on smooth surfaces, the derailleur features and ON/OFF switch for the chain tensioner.
