They don't have the lowest rolling resistance in the world, but pretty low. They don't have the best road grip in the world, but pretty good. They last an above-average number of miles. They're racing tires that function pretty well as everyday riders. I haven't had a puncture flat with one, or their predecessor the 4000S, in over a decade. YMMV if you ride in junk a lot.
