Shimano GRX RD-RX717 12-Speed Di2 Wireless Rear Derailleur

The Shimano GRX RD-RX717 12-Speed Di2 Wireless Rear Derailleur brings true wireless shifting to gravel riding. It delivers strong durability and handles rough terrain with confidence. It supports 1×12 drivetrains and works with cassettes up to 10-51T to tackle steep climbs, fast flats and uneven surfaces. Shimano Di2 wireless technology delivers quick precise shifts without external wires and pairs with 12-speed GRX shifters. A removable internal battery sits protected inside the derailleur body and charges with ease.

Shimano designed the RD-RX717 to take hits with a wide link layout, skid plate and durable pulleys. Shimano SHADOW ES keeps the chain stable, reduces noise and limits chain slap on rough terrain. Automatic Impact Recovery resets the derailleur after impacts to keep shifting consistent. Sealed components protect against mud, dirt and water to ensure long term reliability.

Technology

Shimano’s SHADOW ES
The GRX RD-RX717 derailleur uses the new SHADOW ES, a slimmed down evolution of the Shadow chain retention system. It helps minimize drivetrain noise while improving shift quality on rough terrain.

Automatic Impact Recovery
If a rock strike occurs, the derailleur is designed to move out of the way utilizing bumper-style skid plates. After the strike, a motor unit moves the derailleur back into the gear it was originally in so you can keep riding without pausing.

Shimano Di2 True Wireless Shifting
The RD-RX717 brings true wireless shifting and customization to your GRX 12-speed drivetrain. No wires, no fuss.
