What is a bicycle fork?

A bicycle fork is a structural component of a bicycle that connects the front wheel to the frame. It typically consists of two legs or stanchions, held together by a crown at the top and one or more dropouts and fork ends which secure the front axle at the bottom. Bicycle forks are designed to provide steering capability, absorb road shocks, and support the cyclist's weight and the front wheel. They can be made from various materials, including steel, aluminum, carbon fiber, and titanium. Forks can have built-in suspension or be rigid, and may include additional features such as mounts for brakes, fenders, and other accessories. Suspension forks typically incorporate either coil or air springs and damping mechanisms to reduce vibrations. Fork length, stiffness, offset, rake, and axle-to-crown measurement are some of the critical parameters considered when selecting the appropriate fork for a particular bicycle and riding style.
