Designed specifically for gravel cyclists and adventure riders, this high-performance dual control system combines precise mechanical shifting with powerful hydraulic braking, delivering unmatched control on challenging terrains.

Materials & Engineering

Constructed with durable, lightweight materials, the Shimano GRX RX820 components are engineered for rugged use and long-lasting performance. The high-quality hydraulic caliper utilizes a 2-piston design with increased pad clearance for quieter operation and reduced brake noise, while the ergonomic shifter body is crafted to optimize comfort and control.

The inclusion of finned L05A resin pads enhances heat dissipation, ensuring consistent braking performance even during extended rides.

Technology & Innovation

The flat mount caliper offers a sleek, integrated look and easier installation, while the reach adjust mechanism allows riders to customize lever position for optimal comfort and control, accommodating different hand sizes and riding styles. Its simple, one-way bleeding process simplifies maintenance, ensuring your hydraulic system stays air-free and performing at peak.
