HB's C-Bow system consists of a very compact C-shaped mounting plate that accepts a large selection of HB C-Bow bags. The bracket leaves a nice clean bracket when the bags are removed from the bike. Easy on and off: To attach HB C-Bow bags, just slide them onto the mount, and twist the keyed lock to secure. Simply the easiest and nicest system on the market. Not typically stocked, unless count is shown. For time sensitive orders, please CONTACT us above PRIOR to ordering.
