A bicycle shift control mechanism that has an operating member (35), a wire take up member (51), a positioning ratchet (55) and a position maintaining pawl (56). The operating member (35) is movable between a rest position, a shift wind position and a shift releasing position. The positioning ratchet (55) includes a plurality of winding teeth (55b), a plurality of positioning teeth (55c) and a plurality of movement restricting teeth (55d). The positioning teeth (55c) and the movement restricting teeth (55d) are nonconcentrically arranged to form stair shaped arrangements. The position maintaining pawl (56) selectively holds and releases the positioning ratchet (55) upon movement of the operating member (35) from the rest position. |
