I don't want to keep drilling you with info but I am just trying to help...I looked at CL for you area...now I am by no means tellin you to buy off CL...just letting you see what's out there, in the mean time start looking for shops and try to find one with good customer service that will help you. Here are some bikes being sold in KC
