Product Description
The Shimano GRX RX717 Di2 rear derailleur sits at the core of the GRX electronic drivetrain, delivering fully wireless 12 speed shifting with a focus on reliability and control. Built specifically for gravel and off road riding, it maintains smooth and consistent performance even when conditions get rough.
Designed to handle real world impacts, the derailleur automatically returns to its correct position after a hit thanks to Shimano impact recovery. A wide link layout and integrated skid plate improve durability, while Shadow ES technology keeps the chain stable and secure over uneven terrain. The battery is housed in a protected location that keeps it safe but easy to remove for charging.
The RX717 shares its battery with several other Shimano Di2 systems, making it simple to swap between bikes if needed. On a full charge, riders can expect a range of roughly 700 to 1000 kilometres depending on terrain, shifting frequency, and weather.
The long cage SGS version is designed to work with wide range 10 to 51T 12 speed cassettes. Durable solid pulleys help ensure long term reliability. When paired with the RX715 dual control lever, the system connects to the Shimano E TUBE app, allowing riders to adjust shift speed, customise button functions, and keep firmware up to date.
The GRX RX717 brings Shimano Di2 precision to a more accessible level, expanding high quality electronic gravel shifting to more riders while delivering dependable performance across mixed and unpredictable terrain.
