I read on the Dahon spec page that the seatpost to handlebar distance is adjustable by about 4 inches. I cannot see how this adjustability is accomplished. Is there another adjustment in addition to the sliding of the saddle fore and aft on the saddle rails? I can't see any adjustments on the stem or the steering post. Is there a replaceable stem? Does the steering stem adjust fore and aft?
Please enlighten me!
