【Get Back Riding Fast】: The CXWXC CO2 Cartridges are a new standard of threaded CO2 Cartridge, perfect for whether your going on tough mountain range rides, or in need of fast air pressure during hot pursuit racing! With the 16g threaded cartridges, it can fill a large (26” x 1.95”) MTB tire to 40psi (2.7bar) in a single shot, now that’s impressive! Get yourself back on the trail quick and conveniently with the handy 16 gram threaded CO2 cartridge | 【Super Compact and Lightweight】: The CO2 cartridges are much smaller and lighter than a hand pump, easily fitting into a saddle bag or jersey pocket. The cartridges are full of compressed air and can inflate flat tire in a matter of seconds with little effort. But please note that you'll more than likely find that your tire will be flat (or well on its way to being flat) within 24 hours because CO2 will leak out of your tire faster than air. So don't forget to pump it up before your next ride | 【Compatible for all Threaded CO2 Inflators】: Our 3/8-24 sized threads are compatible with all threaded CO2 bike tire inflators. Note: Once the CO2 is released, the cartridge and inflator head will get extremely cold, so it pays to wear gloves or buy CO2 cartridges with protective sleeves to protect your hands. Once you've finished inflating your tire, Don't leave it on the side of the road for someone else to pick up. CO2 canisters are RECYCLABLE and one-time use only | 【Perfect for Road/ Mountain Bike Tires】: 16 gram cartridge inflates a road tire to 100 psi and a MTB tire to approx. 40psi. NOTE: CO2 gas is ‘not’ food grade. As this cartridge dispenses its air, it rapidly cools and becomes COLD to the touch; care should be taken, protect your hands when dispensing air. IMPORTANT: For safety reasons - do NOT screw in and store a CO2 cartridge into an inflator head until needed for operation. Care & respect should be taken when using CO2 gas | 【WARNING】: Never store the cartridges in or near any hot place, such as under direct sunshine, near a heat source or left in a car. Never use low quality CO2 head. Make sure the device has fully punctured the head of the cartridge. If not, or you find that the gas being released very slowly or the gas is freezing the head, discharge the gas for a few minutes until the bottle is fully empty, then dispose of properly.
