These small and compact 16 gram threaded CO2 cartridges are a breeze to use. They fit a wide range of CO2 pump heads, allowing you to quickly inflate your bike tires while on the move. Each pack comes with 2 cartridges. Capacity varies depending on tire size: 29×2.0 reaches 31 PSI, 26×1.95 gets to 40 PSI, 700x23c can go up to 130 PSI, 700x28c reaches 86 PSI, 20×2.0 hits 48 PSI, and 24×2.0 gets to 42 PSI.

Using these CO2 cartridges is easy. First, make sure your CO2 pump head is compatible with the threaded cartridges. Then, attach the cartridge to the pump head. Next, connect the pump head to your bike tire valve. Once everything is set, release the CO2 into the tire. You'll see the tire inflate quickly. Remember, the pressure you can reach depends on your tire size, as listed on the product details. When not in use, store the cartridges in a cool, dry place. Avoid exposing them to high temperatures or rough handling. Also, be careful when attaching and detaching the cartridges to prevent any CO2 leaks.
