I currently own a '76 Moto Grand Jubile. I also have an article from a 1974 Bicycling! magazine that describes the bike in full detail. Contact me off list if you would like a copy. I believe the first Grand Jubile was offered in '74 and remained the same until '77 when it was changed significantly. It originally came with French diameter Reynolds 531 tubing in the main frame, unknown stays. It was dressed with Stronglight 49D cranks and Stronglight headset, Pivo stem and bars, Weinmann 999 brakes, Weinmann 27" rims with Normandy Sport hubs w/QR, Huret Jubilee front and rear ders. According to the article the frame had Huret drop-outs front and back. My '76 has Huret front and Suntour GS rear drop-outs. In '77 the frame was changed to Vitus tubing (unk type) and Suntour components.
Although not a pro bike, the Grand Jubile rides well, and looks very nice with those Nervex Pro lugs and red/black paint scheme. You've got to love those French bikes!
