I'm currently looking at a deal on a used 2006 Jamis Sputnik, sounds likes it's stock - hoping to go check it out some time this week. I did some searching through the forums, seems like people are happy with it, except for maybe the components which I would probably switch out and try to sell off anyway. Anyone NOT happy with one of these? I'm a little leery of the carbon fiber fork, having had no experience with them. I'm 6'4", 210 lbs -- definitely have encountered some nasty flex and other problems, I'm always wary of other light weight parts. This bike would get daily use.
