Are you saying that the one in the middle is a lot less money than the others? Its the same frame with components that are just as good as the other two bikes.
Appart from the forks being a little less expensive, I dont see how you could buy the middle one if you were poor. I cant even afford the frame alone, never mind the whole build!
the red and black is the Demo I, I just got mine. Its a sick bike with a great build. Just the fact that it comes with a Van RC, a Boxxer Race and a slightly downgraded build drops the price about $2000 retail from the Demo II (white and red)
