Gitane bikes were imported to the U.S. and distributed by Trek in 1984 (note the mention of Waterloo, Wisconsin, in one of the catalogs). There are at least a couple of Bike Forums posters who worked at Trek back then, I believe. Maybe one of them can offer some insight into why Trek made the move to import the bikes and other memories about that period in Trek's history.
