I have a '74 Le Champion that I am in the final stages of restoring for a bicycle show in March. The bicycle is a time machine and is nearly perfect. The problem at hand is that I don't know what kind of tires these bikes came with from the factory. The wheels are Campagnolo Record high flage hubs mated to Rigida clincher rims that have a red oval label that says "Rigida 13-19". The wheels are built with a cross 4 pattern with what appears to be Robergel chrome plated spokes. Each wheel has 36 double butted spokes.
My question is............what brand and type of tire came on these bikes from the factory. If I am unable to source them, what would a good alternative?
Thanks in advance,
