Shimano GRX Di2 RD-RX717 1×12-speed Rear Derailleur
The GRX Di2 RD-RX717 Di2 1 x 12-speed rear derailleur, with new SHIMANO SHADOW ES technology, is offered in a single SGS long-cage spec and was built for durability and functionality. The derailleur features a low-profile wedge design, and the chain stabilizer unit blends seamlessly into the body to minimize exposure to impacts.
For your riding freedom with Wireless Performance: the Gravel GRX Di2 1×12-speed Rear Derailleur RD-RX717 from Shimano
The GRX RD-RX717 rear derailleur, paired with a 10-51T 12-speed cassette, gives gravel riders the speed, range, and robustness to pursue any gravel challenge. With built-in Automatic Impact Recovery, an impact-deflecting shape, and solid pulleys, this derailleur stands up to hard impacts and still retains its lightning-quick shifting performance. It also features the same battery featured on GRX RX827, XTR M9250, XT M8250, and DEORE M6250 derailleurs, so you can swap batteries between your mountain and gravel bikes.
- Fully Wireless Di2 Platform – Designed for ultimate reliability, the wireless Di2 system offers fast, precise shifting and compatibility with all SHIMANO 12-speed wireless shifters (GRX, DURA-ACE, ULTEGRA, SHIMANO 105 Di2 drop bar options, as well as XTR and DEORE XT flat bar Di2 models).
- Robust Gravel Drivetrain – Borrowing its design from SHIMANO’s MTB Di2 line, the RX827 rear derailleur features the same low-profile design, skid plate, protected battery, and automatic impact recovery function.
- Refined Ergonomics – Enhanced grip, clean cockpit design, and unparalleled customization for superior handling and comfort.
- Expanded Versatility – Added GRX component options allow riders to optimize performance based on terrain, style, and personal preferences.
The new GRX 1×12-speed drivetrain pairs the RD-RX717 wireless rear derailleur with SHIMANO’s existing RX715 Di2 DUAL CONTROL LEVERS, RX715. This combination delivers SHIMANO’s hallmark Di2 performance in a sleek, robust 1×12-speed package. Riders can choose between 40T or 42T chainrings and pair them with SHIMANO’s line of 10-51T MICRO SPLINE cassettes. Similarly, RX717 offers an electronic option for drop bar mountain/adventure bikes that utilize mountain bike crank standards. Whether climbing steep trails or cruising flat stretches, the GRX system adapts to any riding style or terrain.
