Shimano GRX RX812 Brake Lever
Best secondary hydraulic brake for gravel cyclists seeking extra stopping control.
These sub-levers provide essential braking confidence when you’re riding on the tops, turning technical gravel descents into manageable terrain. You sacrifice a bit of handlebar real estate, but the added control and safety make them an indispensable upgrade for any serious off-road build.
