Small and light weight, this combo CO2/hand pump bicycle tire inflator will always keep your tires up and running. Fully controllable CO2 bicycle tire inflation along with high pressure hand pump built right in makes this the only pump/inflator you’ll need to carry. Works with threaded CO2 cartridges only. To inflate with CO2, screw CO2 cartridge into pump head, attach to valve stem (presta only) and twist cartridge to inflate tire. For manual inflation, attach pump head to valve stem and begin pumping. It’s that easy!
