Shimano GRX RX717 SGS Di2 Rear Derailleur

The Shimano GRX RX717 SGS Di2 rear derailleur brings wireless shifting to a broader audience of adventurous cyclists. This model is designed to tackle the toughest gravel trails, with reliability and speed at its core. Thanks to its integration with the Di2 platform, every shift is smooth, precise, and lightning-fast, regardless of the terrain or weather conditions.

This model features innovative Shadow ES technology, providing a slimmer profile and superior chain stabilization. This minimizes chain slap and keeps the drivetrain exceptionally quiet on rough terrain. In addition, the derailleur is equipped with Automatic Impact Recovery, an intelligent mechanism that disconnects the internal motor in the event of an impact to prevent damage, after which the system immediately returns itself to the correct position.

Thanks to its long SGS cage, the derailleur is optimally suited to a wide-range 12-speed setup, making it an excellent match for a 10-51T cassette. Its robust construction with a durable aluminum guard plate ensures a long service life and maximum protection for the removable battery. The high-quality finish delivers consistent performance in all conditions.
