The Shimano GRX ST-RX820 right 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 SERVO WAVE brake lever action provides greater braking power with improved control.
