ABSTRACT:
A bicycle shift operating device is provided with a support structure, a take-up unit and a shift positioning mechanism. The support structure has an inner wire fixing part. The take-up unit includes a rotating body mounted on the support structure to rotate about a first axis, and an inner wire routing pulley mounted on the rotating body to move with the rotating body about the first axis and to rotate independently of the rotating body about a second axis that is offset from the first axis of the rotating body. The shift positioning mechanism is operatively coupled to the take-up unit to selectively hold the take-up unit in one of a plurality of shift positions.
