Co2 Bike tire Inflator is the easiest and fastest way to inflate a tire. It is a CO2 filled cartridge that is used with an inflator head attached to the tire valve stem to drain CO2. It is available in a variety of sizes. Tyre filled CO2 cartridges are commonly available in 16g, 25g sizes, threaded and non-threaded cartridges. Compared to a traditional manual pump, the CO2 tyre inflator is smaller, lighter and easier to carry around, so you can attach it to your bike or carry it in a backpack.
