bicycles have been my primary transportation since i was about 10. (i'm 37.) i've been pushing the same 45-lb mtn bike since 1994, and recently started thinking about getting a lighter, faster bike for cargo-free trips. from there it went something like this: That Surly Cross-check looks nice, but it's $900. Um, maybe a singlespeed would be cheaper. Wow, look at those fixed-gear bikes.
Then i got a fixie (about a month ago) and you know the rest!
