Ran a pair + a rear for a while. They're pretty goo until they start to wear down, then any form of puncture resistance goes to shit. Coloured ones skid through like a hot knife through butter. Gatorskins are still my fav.Have you run the Zaffiro's before?
I've got a set on at the moment and so far so good, just wondering how they will pan out in terms of wear and puncture resistance...
