Got a flat right out of the barracks from some ass who felt the need to throw a beer bottle in the streets. didnt see it til the last second, I was about a 1/4 way down when i started hearing deflation, walked the bike the rest of the way. I had to ride it to the bike shop as walking just too waay to long for my break so I pretty much kept the handle bars straight w/ my fingers to keep weight off of it and went slowly. at the bike shop, found I was wrong about my tire diameter.. reset my speedo accordingly, and Turns out I ride faster then I thought
