Description
The SHIMANO GRX RX400 Rear Derailleur was developed to meet the growing popularity of Cyclo-cross and Gravel riding, and the significant constraints they place on derailleurs originally designed for road use.
It features a chain stabiliser with Shadow RD+ technology (borrowed from mountain biking) which prevents chain drops. A switch is located at the upper jockey wheel and when activated, it holds the pivot more firmly and reduces vibrations.
This model, designed for Double Chainrings, can be paired with a 36-tooth cassette sprocket for greater flexibility.
