What was interesting about the A-D/Puch line back then was, unlike many other Euro made bikes, they were definitely not beholden to just use European made components on their bikes, so even the top models had Shimano (Dura Ace and 600, IIRC) groups installed on them. Could be the first Euro bike company that really realized how well the Japanese components were made and how they most of the time, functioned better than their Euro counterparts.
