Shimano GRX Di2 RD-RX717-SGS 1x12-Speed Rear Derailleur

The GRX RX717 rear derailleur is designed to handle the unpredictable demands of gravel riding. Paired with a wide 10-51T 12-speed cassette, it delivers the range and reliability needed to tackle steep climbs, fast flats and everything in between.

Precise and Lightning-Fast Di2 Shifting: With Shimano’s advanced Di2 electronic shifting, the derailleur ensures quick, accurate gear changes in every condition. Whether you're pushing hard or riding technical terrain, shifting remains smooth, responsive and consistent.

Impact-Resistant Design for Tough Terrain: Featuring an impact-deflecting shape and Automatic Impact Recovery, the derailleur is built to handle hits and keep performing. It absorbs shocks and returns to position, maintaining shifting accuracy even after unexpected impacts.

Cross-Platform Battery Compatibility: Designed with shared battery compatibility, this derailleur uses the same battery found in GRX RX827, XTR, XT and Deore Di2 systems. This allows easy swapping between your gravel and mountain setups for added convenience.

The Shimano GRX Di2 RD-RX717-SGS 1x12-Speed Rear Derailleur delivers durability, precision and adaptability, making it a powerful choice for riders who push beyond the paved road.
