funny you post this, go to the mission workshop site there's a video on there featuring their messenger bag on a rider in France and he hauls his dream frame from one location to this LBS
I got a call today from my wheelbuilder that my wife's weight weenies wheelset was done and ironically i was commuting home so i thought how would one haul a set of wheels w/ a backpack/messenger bag.
But i would like to see how you hauled that frame w/ your MW Backpack
