all the cool kids know that you don't need an NJS stamped track frame with bmx stems and ugly risers to do tricks.

but seriously, i think this "fixie trix" thing is getting out of hand. it's not cool to have your crotch on your handlebar while you do skidzz or bend your fork with your mom's car so you can barspinzz. i'm an avid skater also myself and skateboarding tricks don't come in a few days, it takes months and maybe years. anyone can learn how to barspin and skid in days. like many other people have said, go get a bmx. it's cooler and won't hurt your crotch if you miss a trick.

p/s: i'll bet you some of the people in the videos posted don't even know who eddy merckx and theo bos are.
