Description

The SHIMANO GRX 820 Di2 Straight Lever and Rear Caliper sets a new benchmark for wireless electronic drivetrains in Gravel. Its DUAL CONTROL system offers fast, precise and fully connected gear changes, for a smooth experience on any terrain. With a battery life of 3 to 4 years thanks to CR1632 batteries, you benefit from long-lasting reliability and a streamlined cockpit.

The GRX 820's ergonomic handle has been redesigned to fit flared hangers perfectly. Its raised shape, textured surface and non-slip coating on the brake lever guarantee optimum comfort and total control, even on the most demanding trails.

This model is compatible with SHIMANO SW-RS801 satellite controls and features the FRONT SHIFT NEXT function, allowing you to fully customize your shifting configuration to suit your riding style.

The GRX BR-RX820 brake caliper offers improved modulation, quieter braking and simplified maintenance. With its 10% extra pad spacing and optimized bleeding system, it ensures power, reliability and control in all conditions.
