Bicycle CO2 Cartridges

Restore tire pressure in seconds and tackle flat tires on the trail or tarmac with our Bicycle CO2 Cartridges collection. Designed to work with standard thread-on and push-on CO2 inflator heads, these compact, high-pressure cylinders provide the high-volume burst needed to set stubborn tubeless tire beads or inflate tubes without tedious hand pumping. Choose from 16g threaded cartridges tailored for high-pressure road tires, 25g threaded cartridges designed to fill high-volume gravel and mountain bike tires, or insulated safety cartridges featuring protective foam sleeves to shield hands from freeze burns during discharge. Manufactured with 100% recyclable steel and micro-sealed zinc plating, these lightweight cartridges provide reliable, fast inflation for every emergency repair kit.
