Shimano GRX 717 Di2 Wireless Rear Derailleur
At the heart of the system, the GRX RX717 Rear Derailleur offers fully wireless operation with rugged reliability and seamless 12 speed shifting. Designed for gravel and off-road use, it delivers consistent performance even in demanding conditions.
Shimano Impact Recovery and Durability
Automatic Impact Recovery instantly returns the derailleur to its original position after a knock. The wide link structure and integrated skid plate provide exceptional off-road durability, while SHIMANO SHADOW ES technology ensures superb chain stability and security. A protected battery housing keeps the removable battery safe yet easily accessible for charging.
Shimano Battery Compatibility
The RX717 uses the same battery as GRX RX827, XTR M9250, DEORE XT M8250 and DEORE M6250, making swaps between bikes straightforward. The rechargeable battery offers a range of 700 to 1,000 kilometres depending on riding conditions.
Shimano GRX Extended Features
The long cage RD-RX817 SGS version accommodates Shimano 10-51T 12 speed cassettes. Solid pulley construction ensures reliability over time. Paired with the RX715 DUAL CONTROL lever, the system is compatible with Shimano’s E-TUBE app, allowing riders to customise shift speed, button functions and update rear derailleur firmware.

About Shimano
Shifting the way the world rides.
From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.
Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
