Got 2 flats total in the last year. Roughly 120km a week riding. One was on a tubular that was worn out but good thing about tubulars is that I was able to ride my bike a couple of kilometers to a local shop to replace it. The second flat I got was last week. Of all the tires...Gatorskins that were only 2 weeks old. The side was torn for some reason. Kinda bummed because I built a set of clinchers for commuting but I never had any problems with my tubulars.
