Description

The SHIMANO GRX DI2 RX817 11V Rear Derailleur offers the best of technology Di2 technology technology to Cyclo-cross and Graveland responds to the heavy demands they place on derailleurs with an initially road-going profile.

It features a chain stabilizer with Shadow RD+ technology technology (borrowed from mountain biking) to prevent chain jerking. A switch is located on the top roller and, when activated, holds the pivot more firmly and reduces jerking.

This model, designed for Single Chainringcan be combined with a 42-tooth cassette gearing for greater flexibility.
