This is the Genuine Innovations SecondWind Road Mini Aluminum CO2/Hand Pump Combo System. The SecondWind Road pump will inflate your road bike tire to 90 psi in less than 100 strokes! Not fast enough? Hit it with CO2 and get back on the road in no time. Small and light weight, this combo CO2/hand pump 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. Just twist to inflate. 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!
