The tires were stored rather properly...no cracking on sidewalls or tread to indicate drying. And they mounted quite normally on current day 700c rims. I bought them probably back in the early to mid 80's. Kevlar bead...had they shrunk that much proportionally, mounting would have been impossible.

not sure, but is it possible that they shrunk some? how old are the tires? i know with modern tires, different makers 700x23's are all different. also same with rim sizes. michelin tires on shimano wheels are close to impossible to put on, despite their both being 700c. also, sometimes old dryrotted tires are a pain to get off. maybe due to shrinkage???

List- I was rooting through old stuff and found some Specialized Turbo Infinity/SK4 tires marked 700x25. I was going to toss them, but decided to do a trial mounting and see how they would do. Great, as it turns out, but I noticed the actual size of these 700x25 tires to be smaller than the current day 700x23 tires I removed, which were Conti Grand Prix 3000s. Both measurements, across and off the rim, were smaller. Why is this? Have the numbers come to represent something different? They could be mis-sized, but I recall back in the day during the introduction of skinnier clincher tires that 25c would be the narrowest I would want to ride on the road, and today I'm riding 23c tires with no consideration. Well, I guess because they're bigger. So, have tires come to reflect the overall cultural obesity situation or is there some other "inflationary" cause for this? Anyone else notice this in older tires? Was this a gradual change or did I miss a tire sizing revolution somewhere?

Optimistic sellers just put a little ray of sunshine into the world, you know?
nice bike, but I'm thinkin' no more than 700-800 bucks in this, or any, market.
Be interesting to know what it ultimately sells for.
