Here we are going to present the history of these exceptional race chassis of constructor Peter Haider. They were built in the middle of the 80s and successfully raced in national and international competitions by riders like Walter Prünner, Martin Wurm and Horstl Scheuer. As a special we will present a bike which is ridden on the road and one which is presently successfully raced in the United States. As a foretaste already some photos of these ingenuous constructions. Everybody who can contribute photos or stories around this subject is requested to contact Gert Schnögl (phone 01/5449377, e-mail: gert.schnoegl@netway.at).
