I tried a search here, but didn't have much luck (or maybe it was too much). Anyway, I adopted a couple of road bikes and am going to try cleaning them up and making them functional again, but the first thing I noticed is that they have 27" by 1 1/4" Araya? rims. Can I put 700c tires on these rims, since that seems to be what all the stores carry today? I know, to a regular road rider this is probably one of the dumbest questions put forth, but I've always been a MTB enthusiast and this is all new to me. Duh! My 27.5's are shorter than these 27's. That's just wrong... Thanks in advance for any and all comments.
