Hi CR list and David, The early 1970's Gitane catalog that I now have thanks to John Barron (Velo Stuf),from Cirque 2006 states that the GITANE,model Tour de France came originally equipped circa 1971 with:DURAL MAVIC MONTHLERY rims, which would be aluminum tubular (sew ups) rims.The only other Gitane using this same model rim circa 1971,would have been the Gitane "Super Corsa,the top road racing Gitane at the time. The third tier Gitane road racing bicycle was the Gitane "Interclub" and it used the tubular rim, DURAL MAVIC SPORT (aluminum tubular). The top tier touring Gitane,GRAN TOURISME, used the DURAL MAVIC CLINCHER 27" X 1 1/4". Yours truly, Marty Walsh in Vienna,Va.
