Optimized for single-chainring drivetrains, the Shimano GRX BL-RX610-L brake lever delivers greater comfort and control for mixed-terrain riding thanks to Shimano's category-leading hydraulic disc brakes and gravel-specific design features. The RX610 brake lever is paired with a GRX BR-RX410 flat mount disc brake caliper that brings a new level of control to gravel cycling with enhanced modulation and a quicker initial braking point. Despite its compact construction, the system is quieter and easier to maintain.
