Part of a new range of components that bring reliable, smooth gear shifting to your gravel and adventure riding, the GRX 810 Mechanical 11-Speed Rear Derailleur has been engineered to deliver crisp, uninterrupted shifting regardless of the road surface. An innovative adjustable stabiliser keeps the chain tight so that chain slap is eliminated, leaving your drivetrain quiet and predictable.

About Shimano
Shifting the way the world rides.
From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.
Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
