there have been very similarly worded ads for hubs and such on craigslist philly, i think that thing is filled with bored bike shop employees(actually i know, my younger brother keeps buying bikes from the same bored bikeshop employee off of craigslsit), build up a sweet ride at employee prices and dump it for a slight profit (or atleast maybe no lose) when you're looking for a new project, not a bad way to kill boredom honestly
