Shimano GRX BR-RX820 Rear Disc Brake

Key Features

• Hydraulic Disc Brake System
  The BR-RX820 uses hydraulic brake technology, offering superior braking power and modulation compared to mechanical disc brakes. Hydraulic brakes are known for their smooth operation, excellent stopping power, and consistent performance, even under heavy braking conditions.

• Powerful and Precise Stopping Power
  The GRX BR-RX820 is engineered to provide strong and reliable stopping power, even in wet or muddy conditions, which is essential for gravel riders who face unpredictable terrains. The brake provides excellent control over your speed, especially during technical descents or fast gravel road rides.

• Specifically Tuned for Gravel Riding
  Designed specifically for gravel and mixed-terrain cycling, the GRX BR-RX820 is optimized for gravel bike geometry and ride characteristics. It delivers precise braking with a focus on stability and modulation, which is important for maintaining control when navigating rough, uneven, or loose surfaces.

• Larger Brake Rotor Compatibility
  The BR-RX820 is compatible with 160mm, 140mm, and 180mm rotors, providing versatility for different riding styles and rider preferences. Larger rotors are ideal for riders who need extra stopping power, especially when carrying heavier loads or riding steep descents.

• Ergonomic Design
  Shimano’s GRX series is built with ergonomic considerations in mind. The brake lever design offers comfortable ergonomics for extended gravel and adventure rides, reducing hand fatigue. The lever is designed to work seamlessly with Shimano's GRX shifters, providing smooth integration for efficient shifting and braking.

• Improved Brake Modulation
  The BR-RX820 features Shimano's refined brake modulation, giving riders greater control over braking force. This is important in gravel riding, where a smooth, controlled stop is necessary when navigating technical sections or sharp turns on loose surfaces.

• Ice-Tech Cooling Technology
  Shimano’s Ice-Tech technology helps to dissipate heat and maintain consistent brake performance. The BR-RX820 benefits from heat management features, which help prevent brake fade and improve overall braking efficiency, especially during extended braking sessions on longer descents.

• Durability and Maintenance
  The hydraulic brake caliper is built for durability and designed for easy maintenance. Shimano’s proven One-Way hydraulic caliper design allows for easier pad adjustment, reducing the amount of maintenance required over time. This design also ensures reliability in tough conditions, which is vital for gravel riders who often encounter dirty and gritty environments.
