  • Patent number: 5599034
    Abstract: A bicycle fork is used with a bicycle having a conventional head tube. The fork has a steering column that is supported in the head tube and carries a forwardly-connecting stem on which the handle bars are mounted. At the bottom end of the steering column is a control arm pivotally connected to the steering column and extending forwardly to be connected pivotally to the fork crown. The fork crown is connected to the stem at the top of the steering column by a spring-damping shock-absorbing strut, pinned at the top to the stem. The system may be used on a standard bicycle without altering the head tube or the bicycle geometry to provide a shock-absorbing action at the front of the bicycle. By arranging the control arm at an appropriate angle to the strut, an anti-diving action is incorporated into the fork.
