Description

The SHIMANO GRX DI2 RX817 11-Speed Rear Derailleur brings the best of Di2 technology to Cyclo-cross and Gravel riding, meeting the significant demands they place on derailleurs originally designed for road use.

It features a chain stabiliser with Shadow RD+ technology (derived from mountain biking) which prevents chain drops. A switch is placed at the upper pulley and when activated, it holds the pivot more firmly and reduces vibrations.

This model designed for Single Chainring setups can be paired with a cassette sprocket of 42 teeth for greater flexibility.
