Shimano GRX ST-RX820 Hydraulic Disc and BR-RX820 Calliper

Shimano GRX ST-RX820 Hydraulic Brake Lever and BR-RX820 Caliper

The GRX ST-RX820 Hydraulic Disc Lever and BR-RX820 Caliper delivers light and responsive mechanical 12-speed shifting for mixed-terrain riding and racing. The ergonomic shifter design improves comfort by decreasing pressure on your palms, while the textured, anti-slip brake lever surface increases control on bumpy terrain.

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.
