Abstract: A front suspension fork assembly for a bicycle comprises a hollow head tube with an enlarged lower end, and a hollow steerer tube with an enlarged lower end rotatably mounted in the head tube by aircraft-type bearings. A standard high performance mountain bike shock absorber is mounted internally in the lower end of the steerer tube. A standard steerer stem is mounted on the top of the steerer tube. A front fork comprising a pair of parallel fork arms interconnected by cross members is mounted to the steerer tube by a four link pivoting mounting mechanism. The mounting mechanism comprises an upper and lower link mechanism mounted to the steerer tube above and below the head tube. Each link mechanism comprises a pair of laterally spaced pivot links pivotally attached at rear ends to pivot link brackets attached to the steerer tube. The pivot links extend forwardly to forward ends, which are pivotally attached to the fork at longitudinally adjustable positions on the fork.
