JYC: braze-ons

Trying to figure out where to put the braze-ons for Jean-Yves' frame, particularly the brake studs for a Mafac Raid brake on a 650B rim. I found a Mafac 1979 poster online with all the spacing, positioning specs, that helped a lot.

J'essaye de determiner ou placer les petites pieces de cadre due le cadre de Jean-Yves, en partuclier les tasseaux pour les freins Mafac Raid. J'ai trouvé un poster Mafac de 1979 qui liste toutes les specifications, ca aide.
