I ride Paselas, Zafirro's, and Gatorskins or different c&v bikes...all great tires. I am an admitted Schwalbe hater, they have every characteristic I don't like in tire, except flat protection ... perhaps. Of course the Schwalbe SMS is one of the faster tires in their line, but my 700s were flat magnets for thorns.

I do ride Ultremos on a fast bike, but the wear and durability characteristics are simply terrible.
