Abstract
A damping strut for a bicycle has a hydraulic shock absorber having a damper volume filled with incompressible damping fluid, a pressure application device that detects the current displacement state of the damping strut, and at least one disk valve. When the damping strut is displaced, the damper volume changes so that the damping fluid flows, creating a damping force which counteracts the displacement, through the disk valve. A control piston is coupled to the disk valve in order to vary the degree of opening of the disk valve. Control piston pressure can be applied by the pressure application device with a compressible control fluid, dependent on the displacement state detected by the pressure application device, such that on detection of a pre-determined displacement state of the damping strut, the disk valve is pre-tensioned in the closing direction thereof, so that the damping force is increased.
