The invention also comprises a pair of essentially mutually parallel seatstays, which at one end are pivotally mounted at a second pivot point on the chainstays, this second pivot being situated in the region of the dropouts, and a rocker plate that has three rocker pivot points, that is a first rocker pivot point at which a second end of the seatstays is hinged, a second rocker pivot point at which this rocker plate is rotatably connected to the seat tube, namely in a region between the first pivot point and the upper end of the seat tube, and a third rocker pivot point which is hinged with a first end of a spring suspension device, the second end of which is fixed to the frame.
