Description

Unbelievable Performance

The Shimano GRX RD-RX822 12-Speed Rear Derailleur is a 1x workhorse, designed to push you to victory or just over the next hill. Featuring hot-swappable cages for crisper shifting or wider range, depending on your preferences, this derailleur is ready for anything, even if you change your mind later.

Unbeatable

Riders who love going for personal PRs or duking it out at the sharp end of a race will appreciate the gear steps of the RX820 1x12 UNBEATABLE setup with a 10-45 cassette paired with a 40- or 42-tooth chainring. Just like its 11-speed predecessor, RX820 delivers smooth, reliable shifting but now features a wider gear range and extra cog, making it easier to find the optimal cadence for maintaining your position in the pack.

This setup employs the RD-RX822-GS medium cage rear derailleur designed for use with the 10-45T cassette and includes SHIMANO's integrated SHADOW RD+ chain stabilizer, providing quieter shifting, and secure chain management in rough terrain.

Unstoppable

For all-day—or multi-day—adventures heavy on climbing, the new RX820 1x12 UNSTOPPABLE option features SHIMANO's wide-range, 10-51T cassette along with a 40- or 42-tooth chainring. This setup delivers optimal climbing gears for the steepest jeep roads or high mountain ascents.

The UNSTOPPABLE 1x12-speed setup includes the RD-RX822-GSG long-cage rear derailleur with integrated SHADOW RD+ chain stabilizer that is optimized for use with the 10-51T cassette. New for this generation of GRX is the ability to change or replace the derailleur cage between 1x12 options. This means if you need to replace your cage or your gearing needs change, you don't have to buy a whole new derailleur.

The Next Generation Of Gravel

With the introduction of Shimano GRX RX820 12-speed mechanical components, SHIMANO continues its legacy of innovation as the originator of gravel-specific components. Rooted in simplicity, reliability, and adventure, the new 12-speed GRX lineup delivers more gearing options along with unrivaled ergonomics so riders get the most out each unpaved adventure, wherever that might be. With a focus on the heart and soul of gravel cycling, Shimano mechanical GRX receives this 12-speed upgrade delivering top-tier performance without an over-the-top price. And since gravel is all about personal expression and freedom to choose how and where to ride, Shimano GRX includes three unique 12-speed mechanical drivetrain personalities to cover the full spectrum of riders and rides.

  • 12-speed
  • SHIMANO SHADOW RD+ Chain Stabilization
  • Max cassette range: 45T/51T
