Abstract
A bicycle shifter for pulling and releasing a control cable connected to a gear change mechanism that includes a housing mountable to a handlebar, a takeup member, a control member, a holding mechanism and a release mechanism. The takeup member is movable for pulling the control cable in a cable-pull direction and releasing the control cable in a cable-release direction. The control member is movable in a shift direction from a rest position for a first shift movement to permit motion of the takeup member in the cable-release direction. The first shift movement corresponds to a single gear change. The control member is movable in the shift direction from the rest position for a second shift movement to move the takeup member in the cable-pull direction. The second shift movement corresponds to a plurality of gear changes. The second shift movement is greater than the first shift movement. The control member is biased toward the rest position. The holding mechanism retains the takeup element in a selected gear position. The drive mechanism is operable for releasing the holding mechanism from the takeup member and for moving the takeup member in response to actuation of the control m…
