The SHIMANO GRX RX810 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 Double Chainringscan be combined with a 34-tooth cassette gearing for greater flexibility.

"Easy to adjust and reliable derailleur. Gears shift easily and it doesn't move. Used with the GRX RX600 lever and a 105 R7000 - 11/34 cassette it makes a great combo!"
"Easy assembly, well-designed cable routing, and it goes smoothly from 11 to 34. And aesthetically pleasing."
"A real pleasure to ride. Nothing could be easier. Works like a charm with my Ultegra 6800 shifters. By turning the device on, the clevis hardly moves at all. A real plus for stabilizing the chain."
