ABSTRACT:
An improved vertical tube for bicycles includes a vertical tubular portion of a horizontal tube fitted onto a front fork having a bearing means fitted around its outer periphery such that the bottom of the tubular portion urges against a tapered inner ring of the bearing means, a baffle cap, and a torsion spring having a first end fitted into a small through hole of the baffle cap and a second through hole inserted into a tiny through hole of a stop rod. A bolt is inserted via a central hole of the baffle cap through the torsion spring into a central through hole of the stop rod to be locked with a nut before passing through a threaded hole of a pressing block which is caused to press against the lower inner wall of the stop rod. The pressing block as well as the stop rod and bolt are inserted into the front fork such that when the bolt is turned, the pressing block will cause a lower section of the stop rod to expand to urge against the inner wall of the front fork. The bolt may be turned loose to release the pressing block to permit repair or replacement of the horizontal tube.
