The GRX BL-RX610 Brake Lever with RX400 Caliper is a left side front brake lever, shaped just as the GRX mechanical shift/brake lever is, paired with the Flat Mount BR-RX400 hydraulic disc brake caliper.

Optimized for single-chainring drivetrains, the Shimano GRX BL-RX610 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.
