(This is my second try posting this thread. My wireless internet reception has really been bad this weekend, I think it might have got cut off as I was sending my original post out, since it comes in and out. Please let's not get off topic.)
I was riding up a hill with my friend to his apartment, and I got a flat after hitting the 500th pothole this month. Actually, the tube just leaked for a couple seconds, and then the sealant inside took over. Lower tire pressure, but good to go right? So I take off back down the hill going about 25 and I'm braking the whole time. When I get to the bend at the bottom of the hill, my front tire completely deflates and I'm skidding everywhere like on ice. I throw my foot down and I stop about 50-75 feet later. It was scary as hell!
So, I've learned that a front flat is as serious as Sheldon Brown says it is, to run a back brake unless you're running fixed gear, and that your sole brakes really do suck in an emergency. If I had my track wheels already I think I could have done a quick hockey stop, even without pressure in the front tire. Am I just imagining this? Anyone experienced a front flat on a fixie?
