I gather the OP is sorta packed for packing from the URL. There is the idea that maybe given the limitations of BPs, they should enlarge the part of the equation that is made of large bits of steel. Here is a thought, what about making something out of small lightweight tubes that would hold bags in almost any configuration.


The truth of the mater is that BPs mostly make sense on bikes with dual suspension that make mounting bags difficult, and even there there are several better choices.
