Guys, this will seem like some sort of anachronistic joke, but bear with me. My commuter bike frame is toast so I swapped in another touring frame. All is well, except that my rear Mafac Competition center-pull brake mounting bolt is too short. As you may recall, Mafacs use an M6 bolt with an extremely thin hex head. As far as I know, this type of head is not a terribly standard item. Does anyone know where I can get a longer bolt?
