PORTLAND DESIGN WORKS FATTY OBJECT CO2PLUS SIZED TIRES NEED SOME LOVE TOOIf you have a high-volume tire, then you know that it takes a long time to inflate them. It's even worse with a CO2 inflator because most of the CO2 cartridges out there are designed to work with low-volume road tires. The Portland Design Works Fatty Object CO2 Head is the first CO2 inflator on the market designed specifically to work with plus-sized tires. It is made from a lightweight and durable alloy and fits both Presta and Schrader valves. The oversized control knob makes the Fatty Object easy to operate, even with gloves on. It comes with a 38g threaded CO2 cartridge, a foam insulator sleeve, and will fill a 26x4. 8" tire to 6-7 PSI or a 29x3. 0" tire to 20-22 PSI.
