摘要

A multispeed bicycle hub (20) is controlled by two speed change rods extending within a bore of the hub shaft towards one end of this bore. An operating mechanism is fixed on the respective end of the hub shaft (2). This operating mechanism comprises two cam discs (7, 8) acting onto the speed change rods. The cam discs are rotated by a transmission cable (38) from a speed change switch. The cam discs are rotatable about a common cam disc axis by said transmission cable. The cam discs are provided with respective cam tracks which are located adjacent each other in the axial direction of said cam pivot axis. The circumferential extension of the cam tracks is substantially coextensive about said cam pivot axis. The cam tracks act upon respective intermediate levers which intermediate levers are in engagement with the speed change rods.
