Shimano GRX RX717 SGS Di2 Rear Derailleur

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

This model features the innovative Shadow ES technology, which provides a slimmer profile and superior chain stabilization. This minimizes chain slap and keeps the drivetrain exceptionally quiet over rough surfaces. Additionally, the derailleur is equipped with Automatic Impact Recovery, a clever mechanism that disengages the internal motor upon an unexpected impact to prevent damage, before instantly resetting the system to its correct position.

Thanks to the long SGS cage, the derailleur is optimized for a wide-range 12-speed drivetrain, pairing excellently with a 10-51T cassette. The robust construction, featuring a durable aluminum skid plate, guarantees a long lifespan and maximum protection for the removable battery. The high-quality finish ensures consistent performance under all conditions.
