Familiarity: I've put it through the wringer
If you don't like speeding downhill or twisty roads then these are fine. If you do happen to like either of those scenarios then choose a better tire. They simply don't grip and I've descended with these on my bike and been grateful to see the flat road. I wouldn't trust these for speeds over 30mph, which I routinely surpass. I upgraded as soon as I wore them out ( they came on my Wilier Imperiele) with a pair of Schwalbe Ultremo ZX. Night and day difference, but so was the price. Like I mentioned above, get these if you're just cruising town and don't need the traction for cornering.
