TOPEAK Micro AirBooster 16g CO2

It doesn't get any smaller or lighter! The micro CO₂ inflator milled from an aluminum block is particularly easy to use: screw the Micro AirBooster onto the CO₂ threaded cartridge* and then onto the valve, press to fill - done! Fits Presta and Schrader valves. The new silicone protective cover protects the fingers during filling.
