A shift control device (84) is provided for controlling a transmission control member (80) coupled to a bicycle transmission. The device comprises an actuating component (118) that is manually operated by a rider, wherein the actuating component (118) moves to an actuating component neutral position, to an actuating component upshift position and to an actuating component downshift position. A first biasing component (110) biases the actuating component (118) toward one of the upshift position and the downshift position, and a neutral positioning component (160; 172; 188; 216) positions the actuating component in a neutral position. A transmission control member coupling component (212) is adapted to couple the transmission control member (80) to the actuating component (118) such that the transmission control member (80) moves to a transmission control member neutral position when the actuating component (118) moves to the actuating component neutral position, to a transmission control member upshift position when the actuating component (118) moves to the actuating component upshift position, and to a transmission control member downshift position when the actuating component (118) moves to the actuating component downshift position. <IMAGE> |
