Small hand pumps are no doubt handy and reliable, but if you've ever had to use one to pump up a tire on some hot, remote trail, we're sure you know all too well that it isn't the quickest, easiest way of inflating your tire. It's in these situations where we uncage the Mammoth CO2'FER Mini Pump and let it take over.
The Mammoth CO2'FER Mini Pump might appear to be just another compact hand pump at first glance, but lean in a little closer and you'll be quick to notice that this little guy can also be used with threaded C02 cartridges. This cleverly designed and fully functional mini pump allows a CO2 cartridge to stow away inside, which can be used by unthreading the pump head and using it with the stowed cartridge as a standalone inflator. Might it be one of those rare and unfortunate rides where two flats occur, you can then easily and thankfully resort back to the mini-pump.
We've got to say, its name is almost as clever as its design!
