Description

GRX RD-RX815 11-Speed Di2 Rear Derailleur

The Shimano GRX 11-Speed Di2 rear derailleur brings mountain bike technology to gravel riding with a clutch equipped rear derailleur allowing smooth shifting on rough terrain. The Shadow RD Technology utilizes it's race-proven, low-profile design to offer a derailleur that is more compact and fits closer to the frame, ensuring less damage in a crash. With the adjustable chain stabilizer, chain slapping and dropping are prevented while the gravel-tuned clutch tension provides silent and uninterrupted electronic rear shifting on the roughest terrain.

Features:

  • Operates with Shimano Di2 for digital electronic shifting
  • Toggle clutch ON/OFF to match the terrain
  • Gravel-tuned clutch tension provides smooth and reliable mixed surface shifting
  • Switch stabilizer ON/OFF to match the terrain
  • For 1x and 2x drivetrains
