I've got two NOS tubulars that have no size printed on them, they are CONCORDE CRITERIUM, Made In Singapore. They fit onto my 700C rims OK but they go on with not much effort, I'm used to really struggling with new tubs to get them on the rims, so now I'm wondering if I have a pair of 27 inch tubs, how can I tell?
