GRX Dual Control Lever 2X12s and Brake Caliper
The SHIMANO GRX DUAL CONTROL LEVER 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-RX820 disc brake caliper 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.
