Inflate your tires in seconds. And without any blood sweat and tears. The Airspeed is easy to use, compact, and as the name says, all about speed! Just screw the cartridge onto the inflator and your tire is pumped up before you know it. The CO2 cartridge has a foam cover to protect your frame whilst attached to it. Don't make it too difficult for yourself, use the Airspeed and save some time to go for that extra loop.
