A Deltech cable, or substitute as I have fabricated, increases Dahon's monobeam frame designs to 300 lbs and 10 year warranty. This is of special benefit due to the hinge in the monobeam. The same cable should increase the forward frame strength on a BF NWT as well, but does nothing for the strength of the rear triangle and connections, and, may get in the way of the rear tire swinging underneath the monotube during folding, unless the tire goes to the side of the monobeam when folding; I think yes, because BF Diamond Llama and All-Packa have diamond frames in the same shape and fold fine.
