Bit easier than lugging a 7lb CO2 cylinder, regulator etc etc around.
Already have the injector unit and mini-cylinders - bike tyre quick inflate system.
Got a barbed CO2 disconnect (Normski) and some CO2 hose so I reckon putting an old bike inner tube valve in the end of the CO2 hose will do the trick. To add some CO2 just fit the handheld injector onto the valve and press the button.
What could possibly go wrong!
