As a Norwegian I feel slightly offended by the slur on DBS. They were the Schwinn of Norway with one very sad difference. All their homemade frames are heavy badly made gaspipe beater bikes. But they made their own line of racing bikes in the seventies and eighties with imported frames called Internazionale, Professionale and La Migliore. The two last ones are often very nice bikes with full Dura Ace or Campagnolo Nuevo Record respectively. Frames were either French or Italian. I have a later La Migliore with a frame from Daccordi and Campy Athena wich is a very nice bike.
