Threaded CO2 Cartridges, 25g for Bike Tire Inflators, Box of 5

Inflate a tire in seconds. No pumping. No waiting. No hauling around bulky bike pumps. Combined with an inflator head (not included), Gorilla Force® CO2 cartridges are the fastest way to get back on the saddle. Premium CO2 cartridges. Our factory was qualified by Intertek in 2020 to be ISO:9001 compliant. Translation: certified processes, checks, and tests are in place to crank out consistent, high-quality cartridges. If you do have any problem with your order, please let us know and we’ll make it right. 25g cartridges are perfect for bigger 29” or “fatty” mountain bike tires. They have the same threads as the smaller, more popular, 16g cartridges. However, they likely won’t fit inside “storage canister” style inflators. Check out our smaller 16g cartridges if you have a road bike or 26” to 27.5” mountain bike tires. Single-use and recyclable. They have 25 grams of CO2 inside them, which means they weigh 92 grams when full and 67 grams when empty. They are not refillable, but they are made of steel and can be recycled. 99.99% pure CO2 with no additives or preservatives. They never expire and can be stored between sub-zero and 120 degrees F. Not certified for use with food products.
