GRX RD-RX717-SGS Di2 Wireless Rear Derailleur - 12-Speed, Long Cage, Shadow ES

The Shimano GRX RD-RX717-SGS Di2 Wireless Rear Derailleur brings precision electronic shifting to gravel rides that push limits. Built for the unpredictable mix of terrain that defines the discipline, this 12-speed derailleur balances rugged durability with the smooth, lightning-fast response that makes Shimano Di2 legendary.

Engineered for the demands of modern gravel setups, the GRX RX717 pairs seamlessly with a 10-51T cassette to deliver a massive gear range capable of handling steep climbs, fast descents, and everything in between. Its Shadow ES design keeps the derailleur tucked safely out of harm’s way, reducing chain slap and improving stability when the ride gets rough. Meanwhile, automatic impact recovery helps maintain perfect alignment even after hard hits—because gravel doesn’t always play nice.

Practical details like an enclosed, easily removable battery and reinforced pulley construction mean this derailleur is ready to go the distance, whether that’s a weekend adventure or a multi-day backcountry epic.

Key Features:

• Fully wireless Di2 shifting delivers crisp, reliable performance with zero cable clutter.
• Shadow ES chain stabilization keeps shifting smooth and secure over rough terrain.
• Automatic impact recovery maintains alignment and performance after unexpected knocks.
• Wide link structure and skid-plate design add strength and protection for long-term reliability.
• Removable, enclosed battery stays secure on the ride yet easy to access for charging.

For riders who demand speed, control, and confidence no matter where the gravel leads, the Shimano GRX RD-RX717-SGS sets the new standard for wireless off-road performance.
