Like a car's shock absorber, front fork also moves up and down to absorb road surface imperfections. The spring enables the fork leg to spring back after compressing over a bump. It enhances traction and improves the ride. For the majority of bikes, a spring and oil are located inside front fork tube. It is a portion of the bicycle on which the front wheel is attached and which is turned by the handlebars to steer the bicycle. A steerer tube, crown and fork legs, and a dropout for the receiving wheel axle make up this component.
