I've had the same gatorskins on three different bikes - didn't like them on any of them, too stiff for me. But never had a problem until a ran over a tack one day. Tacks seem to be perfectly design to flat tires. What other device could sit straight up waiting for you to roll over it.

I had a 25 up front and 28 in back, which barely fit the 1st bike I tried. Surprisingly, the 28 measured the same width as the 25, using calipers, but it was a bit taller, if I remember right. I put them on my son's bike so he could thrash them around, worry-free.

I replaced them with 700x32 Conti-contacts on my ss, and I'm really loving those tires. Comfortable, and with some thread for hardpack, which I like. Heavier, probably slower starting up, but don't notice once I'm rolling, and maybe less responsive in hi-speed cornering, but I'm not doing that on my ss anyway. They also run narrower than advertised, like the gatorskins. These are real city tires - sure wish I had them in SF yesterday (took my geared bike instead).
