Do ya guys think I should try for it, I was thinking of maby putting like 5 or 6 hundred for my bid, and if I win a few more to fix it.
I know that you take a risk buying CF used, but its it is a nice XC bike and nice light XC bikes don't come cheep. Thanks, X-ZEN

That would be a trek 8900....and that site rules. They had a Yeti Kokopelli a few months ago for like $700...with discs.

My bad, Ya but would you get it?

Nope...old stuff, old carbon(bad), id put $600 towards a new bike, or keep savin.

So I should just save and blow the whole $1200 on a nice shiny brand new hardtail in december?

get one around march....when the season rolls around, and the old stuff is goin cheap.

thanks
