<p>A bicycle shift positioning device includes a base member (50) adapted to be mounted to a bicycle; a first rotating body (51) rotatably mounted relative to the base member (50); a second rotating body rotatably mounted relative to the first rotating body (51); a positioning member (52) coupled to the base member (50) and having a plurality of positioning elements; a pawl (53) coupled for movement with the first rotating body (51), wherein the pawl (53) moves between a positioning member engaging position and a positioning member disengaging position; a pawl control member coupled for movement with the second rotating body; and a pawl biasing mechanism (54) for biasing the pawl (53) toward the positioning member engaging position. The pawl control member allows the pawl (53) to move toward the positioning member engaging position when the first rotating body (51) is in a first rotational position relative to the second rotating body, and the pawl control member causes the pawl (53) to be in the positioning member disengaging position when the first rotating body is in a second rotational position relative to the second rotating body. <IMAGE></p> |
