Shift/Brake Lever Shimano GRX ST-RX820 Left, 2-speed

The Shimano GRX ST-RX820 is a left-hand 2-speed STI Dual Control lever developed specifically for gravel and cyclocross riding. It combines precise front shifting with powerful hydraulic disc braking in one ergonomic unit, delivering enhanced control on mixed terrain and confidence on technical sections.

The gravel-inspired lever and hood ergonomics ensure a natural hand position and comfortable grip, even on long rides. An anti-slip textured brake lever improves grip in wet and dusty conditions.
