Shimano GRX RX610 Shift/Disc Brake Kit - Front

Shimano GRX RX610 Shift/Disc Brake Kit - Front Shimano's GRX groupsets have always been designed to bring smooth shifting, reliable braking, and comfort to gravel riding. The Shimano GRX ST-RX610 hydraulic brake/shift levers use trickle-down technology from the original GRX 800 series to bring all the GRX performance and qualities to a more budget-friendly tier.
