Shimano GRX RD-RX717-SGS Di2 Rear Derailleur

The GRX RX717 rear derailleur, combined with a 12-speed 10-51T cassette, provides gravel riders with the speed, gear range, and robustness needed to tackle any gravel challenge. Thanks to the integrated Automatic Impact Recovery, impact-deflecting shape, and sturdy pulleys, it withstands even strong impacts while maintaining lightning-fast shifting performance. It also uses the same battery as the GRX RX827, XTR M9250, XT M8250, and DEORE M6250 derailleurs, so you can easily swap batteries between mountain and gravel bikes.
Product features
Designed for wireless electronic Di2 shifting
Advanced Shadow ES technology for chain stabilization and quiet operation
Automatic position recovery function in case of impact
Slim design and increased ground clearance for better off-road protection
Powered by a replaceable and easily rechargeable Shimano BT-DN320 battery
