Shimano GRX ST-RX820/BR-RX820 12-Speed Shifter/Brake Combo


Comfort For The Long Rides

GRX's ergonomic distinctiveness continues with its redesigned ST-RX820 Levers. Adding 12-speed shifting without any additional lever bulk, the RX820 series shifters are designed for all-day comfort when using flared drop bars, a gravel cycling staple. By reducing pressure points and increasing surface area, your hands will feel less fatigued, and you'll be better in control as you test your limits.

The new GRX shift/brake levers offer light and responsive mechanical 12-speed shifting. While the left lever of the UNDROPPABLE 2x12 GRX group delivers Shimano's unrivaled smooth front shifting, the new 1x12 groups carry over functions for the left lever first introduced with the original GRX: brake lever-only model and a dropper-specific option that seamlessly integrates braking and dropper post actuation.

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.
