Abstract:
1. A bicycle shift operating device comprising: a first operating member arranged to move between a first rest position and a first wire operating position; a second operating member arranged to move between a second rest position and a second wire operating position, the second operating member being operatively coupled to the first operating member to move with the first operating member during movement of the first operating member from the first rest position to the first wire operating position, and to move the first operating member during movement of the second operating member from the second rest position to the second wire operating position, the first and second operating members being configured and arranged to move in substantially the same directions when moved from the first and second rest positions to the first and second wire operating positions, respectively; a shift wire take-up element arranged to rotate in a first rotational direction in response to movement of the first operating member from the first rest position to the first wire operating position, and arranged to rotate in a second rotational direction that is opposite to the first rotational direction in response to movement of the second operating member from the second rest position to the second wire operating position; and a wire winding/release mechanism operatively coupled to the shift wire take-up element and the first and second operating members to selectively hold the shift wire take-up element in one of a plurality of shift positions.
