Shifter & Brake Set Shimano GRX ST-RX820/BR-RX820 Right, 12-speed

The Shimano GRX ST-RX820 + BR-RX820 is a right-hand 12-speed shifter and hydraulic disc brake set designed for gravel and cyclocross bikes. It combines fast and precise rear shifting with powerful braking to ensure maximum control on steep descents and demanding mixed terrain.

Gravel-inspired lever ergonomics and an anti-slip textured surface provide a secure grip even in wet conditions. ICE TECHNOLOGIES cooling reduces heat build-up and ensures consistent braking performance. The Flat-Mount design, J-Kit hose connection and ONE WAY BLEEDING system make installation and maintenance simple and clean.
