Well, this morning, on my commute to work I am glad I had my flat kit. The weather was fair, 34 degrees, no strong wind as I started to work, and then- bam! pothole....front tire flat ssssssssssssssss. I had just aired those tires up before I left the house, I thought. As I am writing this I know it's a pinch flat, I have not examined the tube yet, but I am sure that the tube will reveal the snake bite. Anyway, as I changed the front tire flat it was almost robotic I am glad to have my experience wrenching: assuming front tire is removed from frame, unseat bead, work opposite presta valve, move towards valve stem unseating the bead as you go, remove tube, remove tire, cup hands around tire, place fleshy fingers inside to "feel" for any thing sharp-nothing. Align hot patch (yes, I took the time!) re-seat bead of one side of the tire, blow into the new tube to shape tube insert, re-seat the other side of the tire, starting at the valve move away from valve re-seating the bead as you go, be careful not to pinch the tube on the final re-seating. Once completed ,do a quick visual to make sure the tube is not visable and can be inflated. Inflate using CO2, re-install front tire, quick spin to make sure the tire does not rub, if everything is good to go, get to work.
OK, so I am not the best writer, but this is the first flat that I have had in a long time, +- 600mi of commuting in DC, and I figured it's a good reminder to be prepared. You can bet when I get home tonight I will give my ride some TLC, including some talc on the tubes to help prevent any future pinch flats. So, without further rambling this is what I keep in my camelbak M.U.L.E:
Park Tool TL-1 (3 pry levers)
Ritchey CPR-14
Superflate CO2 (2 replacement cartridges)
700x20-23c PV tube
Last thing, the cause of the flat is a pinch flat, but it I think that it was caused by old rim tape.
Safe commuting,
Van
