Today I pull my bike out to go to school and lo and behold the back tire is completely flat. Turns out I had a flat piece of rock the size of a dime (no exaggeration here) stuck vertically in my tire. The rock went through the tread, tube and scratched up the rim tape too.
I could not figure out how in the world it ended up there and am amazed that it managed to lodge itself in my tire the way it did. Anyways I ended up missing my night class and spent the better part of the last hour replacing everything.
Anybody have any objects stuck in their tire that made you wonder if someone up there just didn't like you that day?
