You're roadside, tire's flat, and it's the second one of the day. You burned your spare tube and CO2 on the first flat, and you're down to your patch kit and inflator. Time to make the call of shame. Unless you happened to stuff the Lezyne Pressure Drive CFH in your jersey, that it. The Pressure Drive CFH functions as both a CO2 inflator, and a pump, so you won't find yourself unable to put air in your tires. To use, just thread a CO2 cartridge directly onto the removable hose, and inflate. Once you've used up your CO2, thread the hose onto the pump, and you'll be able to manually pump your tire up to 120psi.
