Must be in the air....Lost my virginity last weekend on my back tire. Thankfully I was about 1/8 of a mile from my house because I had no spare tubes. Apparently hit a curb a bit too hard, though I have yet to inspect the tube closer to see what the culprit was. I did have a couple in my garage though, got some "thorn resistant" tubes which make the stock Trek tubes look incredibly thin. Thank god for the internet so I could look up how to get the tire off. The rest was relatively easy. But come on, couldn't it be the front tire? My hands were black from chain grease by the time I got everything back on.

Speaking of that, I highly recommend Fast Orange hand cleaner to get that stuff off. Worked like a charm!
