Leave the hand pump behind, forget about tiring yourself out pumping up your tube when you can inflate it with a CO2 cartridge in a matter of seconds. With a compatible threaded inflator, simply pierce the cartridge and before you can blink, you'll have a full tube. The 25g cartridge is great for larger wheels such as 29ers or downhill bikes.
