Rear Derailleur Shimano GRX RD-RX815 Di2 Top Normal 11-speed

The Shimano GRX RD-RX815 Di2 is an 11-speed electronic gravel rear derailleur featuring an integrated chain stabilizer mechanism. It reduces chain slap and vibration, delivering quiet and precise shifting even on demanding terrain.

The adjustable clutch with ON/OFF switch allows you to tailor chain tension to riding conditions – lower resistance on smooth roads and maximum chain control on gravel and trails. The gravel-tuned clutch tension ensures reliable performance on rough surfaces.

The Di2 version offers Shimano electronic and synchronized shifting with digital precision. Compatible with road cassettes up to 34T, the RD-RX815 works seamlessly with road DUAL CONTROL LEVER shifters. Firmware updates are supported via E-TUBE PROJECT.
