In the beginning, there was TeamCow. Who were they? Well, we rode, we rested, we ate, and we drank (not so much of the riding to be honest, but lots of the rest). And then I went on the internet to complain about stuff. It was somewhat popular. I also had The BikeGuide - pics of as many bikes as I could find. Now, they're both back, and always, our motto; "If you think you're in TeamCow, then you are."
Northstar was an aluminum pioneer back in the day. But I guess they just weren't able to convince the masses that they made the bike to own, because I think they went out of business some time ago.
Hardtail - I can't remember at all what the Northstar bike was called. This is a fairly crude looking frame, but remember that few people had used aluminum in a welded application at this time.
