The Intense bikes are sweet. As are a lot of the bikes already mentioned.
Now that Epic has said it, somewhere in the back of my head I'm saying Dummy you knew that! (Turner bikes)
Here in WV you don't often see a lot of high dollar frames. I know 2 riders sponsored by Vicious cycles. Total custom bikes, made to fit you specifically. Most people are buying off the shelf stuff by Specialized, Trek, Gary Fisher. I'd say those 3 brands account for 90% of the bikes I see at races. Even the Rocky Mountain cycles available are special order.
When you strat going into the Freeride arena, I see a lot of Kona bikes around here. Probably because thats what the rent and demo at Snowshoe.
I'm going to take that Hi Fi pro for a spin Monday or Tuesday.
