Abstract:
1. A mechanical operating device comprising: a first output element; a first output element positioning mechanism that positions the first output element in a plurality of first output element positions corresponding to speed states of a first bicycle transmission used to apply a driving force to a bicycle; a second output element; a second output element positioning mechanism that positions the second output element in a plurality of second output element positions corresponding to speed states of a different second bicycle transmission used to apply a driving force to a bicycle; a first input element that moves between a first rest position and a first actuating position; a biasing mechanism that biases the first input element to the first rest position so that the first input element automatically moves toward the first rest position after the first input element is moved toward the first actuating position; and an operating unit operatively coupled to the first input element, to the first output element positioning mechanism and to the second output element positioning mechanism so that movement of the first input element between the first rest position and the first actuating position operates at least one of the first output element positioning mechanism or the second output element positioning mechanism.
