Why does everything have to be so complicated for such a simple bike!
The social dynamics are more complicated then they appear on the surface. There are definately clicks within the click. There is more "hardline" group and several degrees of spiraling outward. In my observations, it seems the fundamentalists are at the track level, then there are the messengers, who adopted fixed gears for simplicity and responsiveness, then you have the hotrod mentality hipsters, with the rare vintage parts from obscure manufactures and then you have the cross over fellas, who ride all sorts of bikes who just wanted to add a different steed to the collection or just to try another style of riding, then there are the roadies using fixed gears for off season training.
This is my observation, it is by no means complete, refined or true to reality. Please add edit or correct my observations. not meant to offend anyone.
