Got a flat for the first time in about 1500 miles this wk w/ my vanilla Vittoria Randonneur tire. Finally got a goat thorn long enough to penetrate... I'd say about 1/2 inch, fresh off the tree or something since it was sharp as a tack. Are the hypers better or worse in this regard? To me it looked like they reduced the amt of rubber for weight reduction and then made up by adding an extra lining of kevlar.
