Why We Love It
Shimano GRX ST-RX820 dual control levers delivers light and responsive mechanical 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. The GRX BR-RX820 2-piston disc brake caliper brings a high level of control to gravel cycling with enhanced modulation and a quick initial braking point. Despite its smaller construction, the system is exceptionally quiet and easy to maintain.

Note: This Item does not included Caliper the Shimano SM-MA-R160D/D Disc Brake Adaptor for 160mm Rotors Flat-Mount Caliper/Flat-Mount Frame. If you plan on using a 160mm rear rotor you may need this adaptor.
