The Shimano GRX RD-RX827 SGS/Long Di2 Rear Derailleur is built to conquer demanding gravel terrain, delivering fast, wireless shifting with unmatched resilience. Paired with a wide-range 10-51T cassette, it provides the gearing needed for grueling climbs and high-speed descents. This next-generation derailleur introduces Automatic Impact Recovery, allowing it to return to its optimal position after a hitso you can stay focused when the ride gets rowdy.

The RX827 also benefits from Shimano’s SHADOW ES design, a slimmer, more durable evolution of their chain-stabilizing tech. A reinforced body, solid pulley design, and protective skid-plate help the derailleur shrug off rock strikes and trail abuse. Plus, the integrated battery is housed securely in an enclosed space to withstand harsh conditions while remaining easy to remove for charging. Whether youre chasing podiums or exploring backroads, the RX827 keeps your drivetrain running fast, quiet, and secure.
