Description

The SHIMANO GRX DI2 RX815 11S Rear Derailleur brings the best of Di2 technology to Cyclo-cross and Gravel riding, meeting the high demands these disciplines place on derailleurs originally designed for road use.

It features a chain stabiliser with Shadow RD+ technology (derived from MTB) that prevents chain drops. A switch is located at the upper pulley and, when activated, holds the pivot more firmly and reduces judder.

This model designed for Double Chainring setups can be paired with a 34-tooth cassette sprocket for greater flexibility.
