Overview
Shift/Brake Lever with Brake Shimano GRX ST-RX825/BR-RX820 Di2 Left, 2-speed
The Shimano GRX Di2 ST-RX825 + BR-RX820 is a complete 2-speed electronic shifting and hydraulic disc brake solution for gravel and cyclocross bikes. High speeds, mixed terrain and unpredictable routes demand maximum control – this set combines precise Di2 front shifting with powerful braking performance in one reliable system.
The ST-RX825 Di2 lever delivers smooth and ultra-precise shifting between two front chainrings, while the Flat-Mount BR-RX820 caliper provides strong and well-modulated braking. L05A-RF Resin pads with cooling fins help maintain consistent braking performance on long descents. The one-way bleeding system simplifies maintenance, and Shimano mineral oil ensures a consistent and predictable brake feel. Together, they provide reliable and precise control in any unexpected situation.
