TIME SAVING & EFFORTLESS: CO2 inflators are the devices designed to inject CO2 gas (via CO2 cartridges) into your bicycle tires. Those 25g 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. Inflates to 30psi for 29" x 2.2" tire. PORTABLE: CO2 inflators are so light and compact, easy to carry around in your saddle bag, 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 weighted 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 heater and oven. Never use low quality CO2 head. Make sure the head punches the bottle fully, check if the gas being released within seconds. If not, or you find that the gas 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.
