What Is a Fork Wrench?
A fork wrench is a tool used for the maintenance of the fork cap on a bicycle.
The fork cap is located at the top of the headset, which connects the metal parts called forks that grip the front wheel from both sides and the frame. Its primary role is in the adjustment of the headset. The headset is a crucial component that enables the handlebars to move left and right, and its adjustment by the fork cap influences ride comfort, durability, and the stability of the ride.
The fork wrench is a thin, metal wrench designed to match the shape of the fork cap. It allows for the application of appropriate torque to the nut and, in some cases, provides the capability to adjust the torque according to the specific requirements.
