Cannondale Airspeed Plus CO2 Mini Pump

The best of both words: dependable manual control and rapid CO2 inflation. Cannondale's Airspeed Plus CO2 Mini Pump is an aluminum, high-pressure pump with a retractable hose and a thread-on, Presta/Schrader head. And, it's compatible with 12- to 25-gram threaded CO2 cartridges so you can start the tube manually, do the majority of inflation with CO2 assistance, and then switch back to a manual pump to set optimum pressure.
