ABSTRACT:
A bicycle shift operating device includes a mounting member, a shift operating member, a take-up member and a retaining mechanism. The mounting member includes a clamping portion and a cover. The shift operating member is rotatably coupled to the mounting member to move in opposite rotation directions. The take-up member is arranged to selectively pull and release a shift control cable in response to rotation of the shift operating member. The retaining mechanism is arranged to retain the take-up member in a plurality of positions. Preferably, a rotational angle limiting structure includes a first limiting portion formed on the clamping portion and a second limiting portion formed on the shift operating member that selectively engages the first limiting portion to limit rotational movement of the shift operating member. Preferably, the cover has a bush integrally formed with the cover as a one-piece, unitary member.
