38g CO2 Catridge

Portland Design Works' 38g CO2 cartridge is made specifically for high volume fat or plus bike tires. To give you an idea of the capacity, it will fill a a 26 x 4.8in tire to 6 - 7psi or a 29 x 3.0in tire to 20 - 22psi. It's designed to work with the Fatty Object CO2 Inflator, and is clean enough on the inside to be rated at food-grade, meaning it won't clog up your inflator or valve stems.
