Abstract:
1. A bicycle shift operating device comprising: a mounting member configured to be fixedly coupled to a bicycle; a shift operating member rotatably coupled to the mounting member to move in a first rotational direction and a second rotational direction opposite to the first rotational direction; a take-up member rotatably coupled to the mounting member, the take-up member being arranged and configured to selectively pull and release a shift control cable; a positioning member rotatably coupled to the mounting member; a first retaining mechanism arranged and configured to retain the positioning member relative to the mounting member; and a second retaining mechanism coupled to the take-up member and the positioning member, the second retaining mechanism being arranged and configured to normally apply a retaining force on the take-up member and the positioning member, the second retaining mechanism being further arranged and configured to reduce the retaining force applied to the take-up member and the positioning member upon moving the shift operating member in the first rotational direction and the second rotational direction.
