38g CO2 Cartridge

The PDW 38 gram threaded CO2 cartridges will fill up your Plus or Fat bike tires. A 38 gram CO2 cartridge will fill a 26x4.8" tire to 6-7psi or a 29x3.0" tires to 20-22psi. They're also food grade, which means they're clean on the inside and won't gunk up your inflator or tire valve.
