You could try a more compact CO2 inflater. My LBS hooked me up w/ one that is very small. The cartridge doesn't fit inside of a housing. It just screws into one end of the inflater and the other end of the inflater goes over the tube's valve. The inflater is very small - about 3/8 inch dia & maybe 1 1/2 inch long.
