The 1974 catalog for my bike which was built in 1972 and sold in either 1972 or 1973 (I am told 73 and 74 models were the same) only says this about the rim/tires: “Tubular (Sew Up) Alloy Rims with Racing Tires”


I expect to get the bike sometime next week, but from the pictures it looks like it has Schrader valve stems, and so I presume somewhere in the past 45 years someone switched to a clincher rim and I assume 27”, however if they are 700c then a wealth of tires are available, though with a Schrader valved inner tube.


Thanks for the Soma tire suggestions I will check them out and yes I have used the Pasela in the past and they are my all time bomb proof winter/tandem tire with a good ride, but as you all mention 27” is an orphan tire and actually it is remarkable that we have the choices that we do.

Thanks again for your help.
