TIME SAVING & EFFORTLESS: CO2 inflators are devices designed to inject CO2 gas (via CO2 cartridges) into your bicycle tires. Those 16g threaded CO2 cartridges are high-pressure. It only takes a few seconds to release the whole bottle of gas. Also great for inflating a tubeless tire.

PORTABLE: CO2 cartridges are so light and compact, easy to carry around in your saddle bag, or backpack, attached on bottle cage holes & under saddles (with special adaptors).

PRECISELY THREADED: Well-threaded cartridges would match the high-quality inflator heads perfectly. It ensures that the cartridge could be screwed right to the end of the CO2 inflator head where the pin punches a hole.

STRICT QC: We understand how sad you feel when you need them. Every Cartridge is weighed before packing in the factory!

WARNING: Never store the cartridges in or near any hot place, such as in the car under direct sunshine, near the heater and oven. Never use low-quality CO2 head. Make sure the head punches the bottle fully, and check if the gas is being released within seconds. If not, or you find that the gas is being released very slowly or the gas freezing the head, please keep discharging the gas for a few mins until the bottle is fully empty.
