I'm quite impressed with what Joe's done. It seems like a pretty big endeavor to me.
Anyhow, if you haven't checked it out yet, I highly recomend it. The list of items is growing and it's so much easier to find specific bike parts than on ebay. I do like ebay, but I hope this site picks up most of their bike-related business in the long term.
Hey Joe, just a thought, but have you considered advertising your new site on places like mtbr.com and pinkbike.com? A lot of traffic in both of those places that might pay off. Like I said, though, just a thought.
