I just warrantied my Gatorskins (700x28) as they were losing thread around the bead (a continuous circle of thread was coming off, on both tires... never seen anything like it). Nashbar of course didn't read the note I included about contacting me through any of the 4 or 5 contact numbers or email addresses that I gave them as I was going to try to replace these with the 4 Seasons (if they would price match wiggle... they won't ). So, still running a new pair of Gatorskins.

These measure 27.4mm on a set of Ambrosio Elite 19 rims BTW. Maybe those would fit your bikes?
