A suspension fork is a component of a bicycle that helps absorb shocks and bumps from the terrain. It is typically found on mountain bikes and some hybrid bikes, allowing for a smoother ride over rough surfaces. The fork consists of two main parts: the stanchions, which slide inside the lower legs, and a spring or air system that provides cushioning. These forks can be adjusted for different riding styles and conditions, making them versatile for various terrains. Features like travel distance and damping settings allow riders to customize their experience, enhancing control and comfort while navigating trails or uneven paths.
