I've managed to go 9 months without a flat & now have had 5 flats on 2 bikes in the past 2 weeks. Both bikes have the newer Gatorskins & those have been great till now. 1 flat was a steel wire that ripped half inch gash through my sidewall, the rest glass shards on different areas of my commute. I'm pretty good about keeping my tires inflated properly & give them the once over before each ride.
Is the cold weather sapping air from my tires throughout my ride? Does the tire rolling over cold concrete some how make tires more prone to flats? Or have the "Flat Gods" just frowned upon me the past 2 weeks? The good news is that I can now change out tubes pretty darn quick.
edit - I just read the "Flat flat flatty flat flat" thread. Perhaps it's just some weird freaky flat phenomenon?
