I've used wire beaded Gatorskins for several years on several bikes. I've obviously been happy with them or I would have tried something else. Last summer I bought a set of 23 mm kevlar bead Gatorskins for my Klein but I geve it to my son to use before I ever had a chance to ride on them. He and his wife had triplett girls a year ago so he hasn't used them very much either.

I've always felt that wire beaded tires were easier to install but, as you can see, some other people have contrary opinions.
