Abstract:
A bicycle shift operating device is basically provided with a pair of operating members and a take-up member. The take-up member pivots in opposite rotational directions in response to movement of the first and second operating members. The first operating member pivotally supports a pawl member having first and second pawls. The first pawl selectively engages and moves one of a release member and a pulling ratchet in response to the movement of the first operating member. The second pawl selectively engages and moves other of the release member and the pulling ratchet in response to the movement of the second operating member. An abutment portion of the first operating member selectively contacts an abutment portion of the pawl member such that the pawls pivot when one of the first and second operating members is operated.
