<p>A bicycle shifter (10) for pulling and releasing a control cable (11) connected to a gear change mechanism that includes a housing (18) mountable to a handlebar (12), a takeup member (22), a control member (20), a holding mechanism (24) and a release mechanism. The takeup member (22) is movable for pulling the control cable (11) in a cable-release direction and releasing the control cable (11) in a cable-release direction. The control member (20) is movable in a shift direction from a rest position for a first shift movement to permit motion of the takeup member (22) in the cable-release direction. The first shift movement corresponds to a single gear change. The control member (20) is moveable in the shift direction from the rest position for a second shift movement to move the takeup member (22) 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 (20) is biased toward the rest position. The holding mechanism (24) retains the takeup member (22) in a selected gear position. The drive mechanism (26) is operable for releasing the holding mechanism (24) from the takeup member (22) and for moving the takeup member (22) in response to actuation of the control member (20).</p> |
