So now I have a few hundred miles on these tires. For the price? I haven't seen it matched. Fast, tough and decent handling. A little heavy (that's where the 0.5 star was demoted) but these are nice tires. Typically I ride sew ups so the ride's a little harsher than I was used to, but the value is not to be scoffed (at). I'm over the ride issues to be sure. For the reviewer(s) that claim the pinch (snake bite) flats are a QC issue? No, no, no -- 100% user error. Now, there are tire / rim combos that are, let's say "challenging" and it's super easy to pinch a tube in those cases. But to blame the tire is crazy. It's unclear if you can pre-stretch a folding tire, but I went for it and mounting it wasn't a big deal (Matrix ISO-C II rims). There are manufacturing defects with tires, typically sidewall issues. I'm picking up another pair and thinking of building a new wheelset and dumping the tubulars. Because of these tires!

Can't beat the price, nice tires, good traction.

These were the pits. I bought half a dozen -- four of them have ripped at the valve stem (which is about as many times as I have had valve stems rip in the entire rest of my 25 year cycling career). I am throwing the two remaining ones out. Cheap tubes are a false economy!
