Shimano - GRX BL-RX812 Sub Brake Lever for Hydraulic Disc Brakes
With the GRX BL-RX812 brake lever, Shimano introduces an additional control option for hydraulic disc brake systems that not only ensures greater safety but also increases the number of grip positions on the handlebar. The sub brake lever is installed on the drop bar top and directly integrated into the closed hydraulic system. So even in dangerous situations, you can brake comfortably and safely without the need to take off the hands from the handlebar. In order to meet the individual needs of the driver, the hydraulic brake lever offers a tool-based reach adjustment as well.
