Description

The SHIMANO GRX RX812 11V Rear Derailleur has been developed in response to the democratization of cycling. Cyclo-cross and Graveland the high stresses 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.
