its a good tire as long as you don't push it too hard in the corners. I find that the transition from the firm center strip to the soft, flexible shoulder tread can get a bit squirrely in deep corners...to the point of feeling dangerous. I moved them to my wife's bike because she isn't likely to be as aggressive as I am. They roll great in a straight line and, in my experience, have fair to good flat resistance. I've only tried them in a 700x32.
