Shimano GRX BL-RX80 Hydraulic Left Lever and BR-RX820 Rear Calliper

Shimano GRX BL-RX80 Hydraulic Left Lever and BR-RX820 Rear Calliper Optimized for single-chainring drivetrains, the GRX BL-RX80 Hydraulic Left Lever delivers greater comfort and control for mixed terrain riding thanks to SHIMANO's category-leading hydraulic disc brakes and a host of gravel-specific design features. The GRX BR-R820 disc brake calliper 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.
