Norris, thanks for the treatise on m. Carre and his frames... This has got me even more intrigued as to what type of Le Jeune I've got... I know it to be from 1982 at the latest, when I accompanied my uncle on the same bike for a ride near the present day Eurodisney on - a mixte Le Jeune, which his wife flattened in her car a few years later mores the pity... It has the RGF bottom bracket the lugs and the trademark braze-ons. 531 main tubes, mafac 2000 centre pulls early dura ace groupset. But no frame number..... And its metallic pink!!!! Any ideas?
