I just got a Chrome Backbone for no other reason than I got a good deal. I figured I make my Jandd messenger bags soley for work and use the Chrome for other stuff so I dont have to empty my paper work out of the Jandds out to make a beer run or go to the gym. Anyway last night I used to carry a crap load of parts home and nothing poked me in the back, not my cranks, not the assorted cogs and chainrings nothing, so far Im very happy with it.
