Wierdness. I had my FIRST flat today, can you believe that crap? Finally, I'm no longer a virgin- it took three years. I just changed tires (Panaracers) and I was using every word in my vocabulary as I was about ten miles from home in sweltering heat with no shade in site. So I take a scene from Christmas Story and time myself on my chrono to see how long it takes to change the tire..lets just say I really really suck. It was like 20 minutes

Anywho...no punctures, no tears, no debris, took the tube out, no holes, the tires AND tube are NEW, about 30 miles on them. SO I decide that since I can find NO leakage or hole, I just put it back on and figured I'd learn from the experience. About two miles later I'm very flat and now since I'm not too far I thought I'd just inflate it every two miles or so (I know, dumb but it was 14,567,899,944 degrees out). So I take out my CO2 thingy and pump her up, and away I ride and she's still hard as a rock as I type this 8 hours later. It's not leaking, what gives? And yes, the little screw down thingy on the Presta was tight. I'm perplexed.
