The SHIMANO GRX RX810 11-Speed Rear Derailleur was developed to meet the growing popularity of Cyclo-cross and Gravel riding, and 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 Double Chainring setups can be paired with a cassette sprocket of 34 teeth 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."
