The vibration damper for a bicycle wheel support comprises a layer of viscoelastic material and a rigid constraining piece fixed to it. The viscoelastic vibration damper has a curved shape to fit around a front fork element or rear strut and is 50-60 mm long. The constraining element is made of a light alloy such as aluminum, zinc and magnesium alloy. The damper is fixed by gluing to the front or rear forks of a bicycle, to the rear of and in the middle section of each arm. It is disclosed that it may also be fitted to the side of, or completely around the fork arm. A wheel support element, a front fork and rear struts comprising the vibration damper are claimed.
