Shimano GRX RD-RX717-SGS Di2 derailleur

The GRX RX717 rear derailleur, combined with a 10–51T 12-speed cassette, gives gravel riders the speed, gear range, and ruggedness needed to tackle any gravel challenge. With its integrated Automatic Impact Recovery function, shock-absorbing shape and solid pulleys, it withstands even heavy 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 Di2 wireless electronic shifting
Advanced Shadow ES technology for chain stabilization and quiet operation
Automatic recovery function upon impact
Narrow design and increased ground clearance for better off-road protection
Powered by a replaceable and easily rechargeable Shimano BT-DN320 battery
