👉 A sprocket is a type of gear component in an automobile or motorcycle, which is used to control the rotation of wheels. It consists of two teeth (sprockets) that are connected at their centers by a chain link. The chain links are connected to the wheel spokes and rotate them around the frame of the vehicle. The sprocket's function is to adjust the direction of rotation of the wheel, allowing it to spin in one direction or another based on the desired speed.
