Description

The SHIMANO GRX Di2 Wireless RX717 12-Speed SGS Rear Derailleur 10-51 Teeth is designed to meet the demands of aggressive gravel riding and extreme terrain. Conceived as the heart of the drivetrain system, it pairs perfectly with a 12-speed 10-51 tooth cassette to deliver an extended gear range and optimal efficiency, even in the most challenging conditions.

Thanks to its Di2 Wireless technology, it delivers ultra-fast and remarkably precise gear shifts. Its extended parallelogram, reinforced aluminium lower guard, steel cage and automatic impact recovery function allow the derailleur to instantly return to its original position after a knock, ensuring reliability and continuous performance on all terrain.

The SHIMANO SHADOW ES optimises chain stabilisation and security, reducing the risk of derailment on rough terrain. The integrated battery compartment is protected against impacts while remaining easily accessible for charging. The battery is compatible with GRX RX827, XTR M9250, DEORE XT M8250 and DEORE M6250 groupsets.

Compatible with the E-TUBE PROJECT CYCLIST app, the SHIMANO GRX Di2 Wireless RX717 12-Speed SGS Rear Derailleur 10-51 Teeth allows customisation of settings, adjustment of shift speed and software updates for a constantly optimised drivetrain.
