These were to compete against the Italian big name bikes, they lacked the high quality graphics the Italians had at the time and a few other details such as many braze ons.
Bertin was not ready to add much to the lighter gauge tubes at the time.
Pretty rare frames, I have never seen one show up on ebay yet.
