ABSTRACT:
A bicycle shift control device is provided for a transmission actuating member, wherein the transmission actuating member moves to a plurality of transmission actuating positions for moving a bicycle transmission to a plurality of transmission positions. The shift control device comprises an operator attachment element that moves among a first operator attachment position, a second operator attachment position, and a third operator attachment position for causing an operation of the transmission actuating member. The second operator attachment position is disposed on a first path of movement from the first operator attachment position, and the third operator attachment position is disposed on a second path of movement from the first operator attachment position. The first path of movement is different from the second path of movement. An operating mechanism operates the operator attachment element so that the operator attachment element can move from the first operator attachment position toward the second operator attachment position and from the first operator attachment position toward the third operator attachment position. A default operator attachment element positioning mechanism sets the operator attachment element to the first operator attachment position when the operating mechanism is in an idle state.
