In this case, DBS is not in reference to the Norwegian brand but to Peugeot's internal (i.e. lugless) brazing process. In 1988, Procycle, a manufacturer of Canadian market Peugeot, signed a license with Peugeot for the use of this technology. In France (and Europe) it was known as PBS or Peugeot Direct Brazing System. To differentiate the Canadian manufactured frames, Procycle called the process DBS (Direct Brazing System). Consequently, the presence of a DBS decal on the subject bicycle definitely indicates a Canadian manufactured model.

In 1990, Peugeot USA went out of business and Procycle took over the USA market, so the subject bicycle could be either a Canadian or USA model. The component group is Shimano 105SC which was manufactured for the 1990-1998 model years, but this is the earlier version without the self-extractor crankset bolts, so the components should be 1990-1992. During this period, the Peugeot model with 105SC was the Triathlon and the frames used an Ishiwata main triangle with generic forks.

It's worth noting that the bicycle is not full 105SC. The headset is 600 Ultegra. Normally, the headset is the component least likely to be changed and it would raise the possibility that the previous owner bought it as a frameset with headset, and built it up with 105SC. However, in this case, that seems unlikely. The Triathlon was spec'd with a cheap steel headset as a cost concession and the Triathlon was the top DBS model during this era. In fact, the Triathlon would switch to lugged carbon fibre and 105SC with STI for the 1993 model year. The decal style, DBS and 105SC with down tube shift levers, all fit nicely with a 1990-1992, Canadian manufactured Peugeot Triathlon.
