Abstract: A bicycle transmission shifting device that includes a cable having a portion of the cable attached to a derailleur and also having another portion of the cable attached to a cable drum. Rotation of the cable drum in one direction pulls the cable to move the derailleur to move a bike chain in a first direction to change gears. Rotation of the cable drum in a second direction pulls or releases tension in the cable to move the derailleur to move the bike chain in a second direction to change gears.

Abstract: A shift assembly and integral handbrake apparatus for bicycles is comprised of a handbrake housing on which pivots a handbrake lever. The housing has an interior region formed with a cavity. A slot, defined by an extending flange, is formed on the housing. A shift lever has one end formed as a shift barrel and the other end formed as a finger paddle. The shift barrel is pivotally mounted in the cavity. A portion of the shift lever is placed in the slot causing the finger paddle to extend from the housing. A Bowden cable is coupled to the shift lever. Means places a frictional drag on the shift barrel. Manual pressure on the finger paddle overcomes the drag placed on the shift barrel causing same to pivot. This pivoting results in a relative lengthening or shortening of the Bowden cable. Means locks the frictional drag means at a given predetermined level. The flange provides a comfortable finger stop.

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.
