ABSTRACT:
A multispeed bicycle having a plurality of front chainwheels, a plurality of rear gears, front and rear derailleurs, and a shifting apparatus operable by a single manual lever to actuate the front and rear derailleurs. The shifting apparatus includes a first actuating mechanism for actuating the front derailleur, a second actuating mechanism for actuating the rear derailleur, and a shift controller for controlling the actuating mechanisms. The shift controller is responsive to operation of the manual lever to drive the first actuating mechanism or second actuating mechanism to produce a speed stage, and responsive to repeated operation of the manual lever to produce all speed stages corresponding to all combinations of the front chainwheels and rear gears.
