ABSTRACT:
A shift control device is provided for controlling a transmission control member coupled to a bicycle transmission. The device comprises an actuating component that is manually operated by a rider, wherein the actuating component moves to an actuating component neutral position, to an actuating component upshift position and to an actuating component downshift position. A first biasing component biases the actuating component toward one of the upshift position and the downshift position, and a neutral positioning component positions the actuating component in a neutral position. A transmission control member coupling component is adapted to couple the transmission control member to the actuating component such that the transmission control member moves to a transmission control member neutral position when the actuating component moves to the actuating component neutral position, to a transmission control member upshift position when the actuating component moves to the actuating component upshift position, and to a transmission control member downshift position when the actuating component moves to the actuating component downshift position.
