NYCBikes dude seems to be the go-to guy for getting quotes about fixed-gear bikes in almost EVERY article in widely circulated pubs that I've seen about fixed.
Why? My main theory is that his shop is the most well-known, high-profile in Williamsburg Proper (i.e. not E.Wburg or Bushwick) and the authors of these articles either live in Williamsburg or consider B-burg to be some sort of de facto fixed gear "fertile crescent", with the East river standing in for the Tigris and Newton Creek the Euphrates. Thus the frequent citation.
But really, I just wanted to make my cradle of civilization metaphor b/c I thought it was clever.
