Product information


The Shimano GRX RX827 Di2 Wireless rear derailleur paired with a 10-51t cassette (cassette sold separate) gives riders and racers the speed, range, and robustness to pursue any gravel challenge. With built-in automatic impact recovery, an impact-deflecting shape, and solid pulleys, this derailleur stands up to hard impacts and still retains its lightning-quick shifting performance.


  • Fully wireless shifting built for rough gravel terrain
  • A wide link structure, skid-plate design, durable aluminum plate and solid pulley add robustness and longevity
  • Automatic Impact Recovery function instantly returns the derailleur to its original position after impact
  • Features Shimano Shadow ES: A slimmer, stronger evolution of Shimano's pioneering chain-stabilizing Shadow RD+ concept
  • Tucked safely inside an enclosed space, the battery won’t budge even in rough terrain, while remaining easily removable for charging
