Abstract: A bicycle operating device includes a base member coupled to a handlebar clamp and a user operated member movably coupled to the base member to move a mechanical control cable with respect to the base member. The base member includes a coupling portion coupled to the handlebar clamp. The coupling portion includes an elongated hole having a long direction extending parallel to a center axis of the handlebar clamp. The coupling portion is coupled to the handlebar clamp via a fastener extending into the elongated hole. The user operated member is movable with respect to the base member between a rest position and an operated position. The bicycle operating device does not mechanically fix a position of the mechanical control cable with respect to the base member in accordance with movement of the user operated member between the rest position and the operated position.
