Okay - I came up with this on a search and I have a, well, similar question. Hopefully similar enough not to be considered a hijack. My tires are labeled with the logo and 23-571, and have an additional stamp elsewhere on the tire that says 26x1. I haven't seen any in the places I've been looking that are anything other than "700." Are my tires *that* much smaller than every other 56cm bike on the planet?
