I am talking to a guy about a used Fat and am questioning his sizing. The bike is a 1986 and has a 31" stand over. The measurement from the center of the BB to the top of the seat post is 20.5". I asked for the measurement to the center of the top tube, but it sounds like he measured to the top of the seat tube.
What size bike do you guys think this is?
