As far as I know there are only 3 of us in my town, me being one, and I know the other two guys. They have KHS's and I have a road conversion. I think if it did ever go mainstream it would become a bit watered down, like both brakes for example, more modern looking designs. One of the things I like about the fixed gear set is the ingenuity and individuality that goes into people's bikes and I think you would see less of that with mainstream popularity. Not that there is anything wrong with buying off the shelf bikes, I would have if I had the money. But I think people coming into it for trend wouldn't be the people converting old bikes or seeking out used frames and parts and piecing their bikes together.

Personally I don't think it will ever hit the way mtb did or bmx, just my opinion. I mean what do you guys consider mainstream, I consider it to mean like back in the day when everyone and their mom off the street was coming into the bike shop to buy mtbs. If you mean mainstream within the bike community then I think it is well on its way if not there. Could you even imagine if it hit mainstream america, I would love to see the Huffy track bikes.
