You will not believe this one.

I went downstairs to the basement this morning, all psyched to ride the Green Hornet to work. I pulled out the pink pump, topped off the new tube in front, and filled the back tire. I do this every time I ride. I pulled off the pump, mindful to pull straight back so as not to bend that little bit that broke off the other valve....and...

WOOSH! TIRE EMPTIED OF AIR!!!

Yes! Horrible but true! The little valve thingy had broken off the BACK tube as well, and when I attached the pump, it just drained the tire. ARGH! And this is the back tire, which I've never changed. Good grief.

So. There I am, dressed to ride, with my work clothes in my Timbuk2, already going to be late for work. To heck with it, I said, and rode the Marin to work. Came home, took the rear wheel off the Bianchi, and brought it upstairs with the pump, new levers, and new tube (me putting the chain back on should be interesting). Now I'm going to eat some food, and get to work on the tire. Let's see how much I've really learned, eh?!? L.
