ABSTRACT:
A mount for supporting a gear shift lever on a tightly undercurved road or racing style handlebar of a bicycle, comprising an annular attachment collar for placement over and close fit to the curve of the handlebar, with the attachment collar securable in place by compression between an existing hand brake lever mount and the handlebar. The attachment collar is defined by an annular wall preferably having varying length allowing for close fit in the inside and outside radii of the tight bend in the handlebar. Extending from the attachment collar is an extending member having a universal shift lever mount stud affixed to a distal portion thereof. The extending member preferably includes one or more angular changes allowing placement of the extending member clear of the brake lever simultaneously with thumb accessible placement of the shift lever relative to normal hand placements on the handlebar. The shift lever mount stud is structured to allow attachment of essentially all existing shift levers manufactured for attachment to the down tube of a bicycle frame, and thus allows the economical re-location of existing shift levers from the down tube of a bicycle upward to the handlebar. Left hand and right hand mounts are provided allowing placing of the rear gear change lever on one side, and the front gear change lever on the opposite side of the handlebar. Cable housing end supports (cable stops) are preferably also attached to the shift lever mounts.
