Epic Fail- sagwagon time.
Last week.
So frustrated about last Thursday's ride home. The parking lot exit at work is paved right through the middle of an empty weed lot and I exit that way. Well, I picked up a huge thorn from some of the weeds that were cut a few weeks ago and did not notice for a block, and then I sure did. FLAT. Crap.
So I get out the pump and patch kit and found a little shade as it's 103f and patch it. Then the hell began. Yes I had found the 1/2" thorn and removed it, checked the tire and the other wheel too. Put it all together, confident that I would just pump it up and go. Nope. Pump-pump-pump. Nothing. I took off the pump and the head of the presta came off and was in the pump head. Ok, get the spare, change again. Pump-pump-pump. Nothing. Shoot. Take off the pump- again the presta nut is broken off. I've never had an issue with the pump before (Blackburn Carbon Frame pump) but I took it apart and I don't see any problem with it. Called the sag wagon and waited in the heat.
I know there is a reason why I look for tubes with removable presta valves for my road bike and mtb, but I had not found any that fit 28~32c tires. Re-thinking this at home, I remembered I had bought some 25c Continental Gatorskins and I switched out. They feel so much better than the Kenda Kwests. But leaving work again this week, I stopped at the exit and sure enough there were 3 thorns in the back, and one in the front. But they had not punctured the tubes yet. So I will leave work out the side exit that does not go through the undeveloped part of the campus.
I've been commuting almost two years now, and that was my first DNF. Gonna get me some tubes with removable valve cores this weekend.
