The first paragraph of the ad begins:
*I'm selling a complete fixed gear. It is totally ready to ride and will probably kill you.
I pushed it into a bike shop recently to have the rear wheel trued. At the bottom of my receipt it read, 'My advice, get a new bike.' So, I am. And maybe you are too! He was reserved enough not to use the words 'death' or 'trap,' but I'm not!*
apparently he couldn't afford a proper track hub so he just used loctite on the freewheel. bought for $80, selling for $350. awesome.
Brilliant ! :D
