Hi there, I had been a long time biker but stopped the sport way back for other reasons in life; picked up MTB biking again last year after this 24 years break, just rescently pull out my 84 Andre Bertin C132 from the attic, starting the rebuild process and getting her road worthy. Here are some pictures of the Bertin:
Current favorites: 1988 Peugeot Birraritz, 1984 Gitane Super Corsa, 1982 Moto Team Champ, 1981 Bianchi Campione Del Mondo, 1992 Paramount OS, 1990 Bianchi Mondiale, 1988 Colnago Technos, 1985 RalieghUSA Team Pro, 1980 Gios, 1973 Holdsworth
Bertin was the importer/distributor for Shimano in France from about 1974 on so they used a lot of those components on their bikes. Bertin shared the Milremo trade name with Ron Kitching in the UK. Kitching was the UK importer/distributor for Suntour.
Bertin stopped producing bikes in the early 90s and concentrated on distributing parts, components and accessories. In 2000 Shimano bought out Bertin and changed the name to Shimano France or something like that.
My 1975 C34 looked like this C37, same colors and so on.
