Shimano GRX Di2 RX717 SGS 12V electric rear derailleur for gravel bikes

Designed to push the boundaries of modern gravel riding, the Shimano GRX Di2 RX717 SGS 12-speed rear derailleur offers fast, precise and completely wireless shifting, even on the most demanding terrain. Compatible with 12-speed 10-51 tooth cassettes, it guarantees a wide gear range ideal for adventure, performance and bikepacking.

Its robust design incorporates SHIMANO SHADOW ES technology, ensuring excellent chain stability and minimal exposure to impacts. In the event of an impact, the automatic recovery system instantly repositions the derailleur to maintain smooth gear changes.

Featuring reinforced pulleys and a protected, removable battery, the GRX RX717 shares the same power supply as recent Shimano Di2 MTB groupsets, making it easy to use the same battery across your gravel and MTB bikes.
