The GRX ST-RX610 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 set detail consists of the left-side ST-RX610 Dual Control Lever and front/rear appropriate BR-RX400 Flat Mount hydraulic disc brake caliper with finned disc pads, and all necessary hardware. The system is pre-bled and connected with the SM-BH90-JK-SSR hydraulic hose system from lever to caliper. Shimano's Mineral Oil hydraulic system makes it fairly simple to set the proper housing length and bleed for best braking contact.
