I'm going to look at a older benotto frame the owner doesn't know much about it. The only picture he sent me shows it has been repainted with no decals he says it has a cinelli bb with an heart cut out. I thought heart cut outs were used by de rosa frames. It does have campy dropouts. If anyone has info on benotto frames I would appreicate it. What tubing did they use on their track frames I thought SL. Are there any tells to know what tubing it is ? Any help would be great.
