I recently posted a thread on the trouble I'm having fitting 27 x 1 1/4 Paselas into a fork that wasn't meant for them. Thanks for all the input. I'd like to keep the bike period correct if possible and these old rims are in nice shape, and, I'm not too keen on spending another hundred bucks on a new set of rims, etc. My question here is, am I flirting with danger using old non-hook bead 27 inch clincher rims? Been doing some reading on various blogs and forums, guys mentioning modern tires like Paselas blowing off old rims with no hook for the bead, ie; straight wall rims from the 70's, trouble getting the tire to seat properly, etc. Were tires built differently back then? What's supposed to hold the tire bead in the rim? When did they stop this practice in rim making? Am I flirting with danger ? ARE THESE OLD THINGS SAFE?
Thanks
