A fork assembly for use in removably mounting a pair of bicycle fork tubes having longitudinally extending upper and lower brackets on a fork mounting tube of a bicycle frame comprising an inner tube rotatably mounted within the fork mounting tube and a rod extending through the inner tube. The brackets have rearwardly extending slots through which the rod passes to engage the fork assembly. A lower spool on the rod is adapted to engage the under side of the lower bracket and an upper spool on the rod is adapted to engage the under side of the upper bracket. The spools are movable longitudinally with the rod within the inner tube. Spring means within the inner tube yieldingly urges the spools into engagememt with the brackets. Locking means is provided on the upper end of the rod and is movable longitudinally of the rod such that when the locking means is moved longitudinally relative to the rod toward the upper surface of the upper bracket, the fork assembly is locked on the brackets, and when the locking means is moved longitudinally relative to the rod away from the upper bracket, the fork assembly can be removed by moving the rod and the spools longitudinally downwardly against the action of the spring means disengaging the spools from the brackets so that the fork assembly can be removed by transverse movement through the slots.
