I have a Schwinn Straight 6 downhill bike that is complete. I haven't been on it for almost two years now. It is in excellent condition and I also have a front derailer and a middle and big chainring that mounts on the front so you can ride it all over, not just downhill. Its a 9spd rear.
I worked at two bike shops so it is very well maintaned.

I have recently reduced the price to $1600 obo. (it cost almost $5k to build)
