ABSTRACT:
A shift assembly and integral handbrake apparatus particularly for bicycles is comprised of a pivotal shift lever and a pivotal handbrake lever. Both levers are carried on a handbrake housing. A Bowden cable is coupled to the shift lever. Friction means places a preset and controlled drag on the shift lever. Pivoting the shift lever provides the mechanical advantage necessary to overcome the drag placed thereon thereby to effect a relative lengthening or shortening of the Bowden cable. The shift lever and handbrake lever are positioned on the housing in such manner as to allow nearly simultaneous grip of both levers.
