ABSTRACT:
A rear housing has a vertical bore for receipt of a bicycle fork tube and a horizontal bore for receipt of a movable piston slightly longer than the length of the horizontal bore. A front housing has a concave rear portion cooperating with a concave front portion of the rear housing to form a gripping enclosure for a bicycle handlebar. Threaded bores in the front housing are aligned axially with threaded bores in the rear housing so that tightening down on the front housing to the rear housing with threaded bolts causes the handlebar to be gripped tightly and the movable piston is urged backwardly to tightly hold the fork tube.
