The Shimano ST-RX820 GRX Dual Control Lever with Caliper provides precise and effortless mechanical 12-speed shifting and braking, perfect for mixed-terrain riding and competitive racing. The GRX ST-RX820 Dual Control Lever with Caliper Set forms the Dual Control STI system mechanical shift/hydraulic disc brake use with GRX 12-speed. The Right set is for the rear derailleur and rear disc brake. It can be used for both 1x and 2x GRX drivetrains. The Left set is for the front derailleur and front disc brake when using the 2x drivetrain. Each side is sold as a set, with lever and pre-bled housing assembly to the Flat Mount disc caliper.

The GRX hood's textured surface guarantees you maintain control, even during rough descents. Thanks to the anti-slip coating on GRX brake levers, you can count on Shimano's renowned stopping power even in wet or muddy conditions. Also, the redesigned GRX RX820 hood features a rounded profile that spreads pressure across a larger area of your hand, guaranteeing lasting comfort during extended rides.

The GRX BR-R820 disc brake caliper brings a new level of control to gravel cycling with enhanced modulation and a quicker initial braking point. And despite its smaller construction, the system is quieter and easier to maintain.
