Lezyne CO2 Cartridge

These cartridges are specifically designed for threaded CO2 inflator heads. They will not work with push-on or non-threaded systems.

A 25g cartridge is generally overkill for standard road bike tires, which typically require 16g. This size is optimized for higher-volume gravel or mountain bike tires where you need more air to seat a tubeless bead or fill a larger casing.

Yes, the 25g capacity provides the high-volume burst of air necessary to seat tubeless tires effectively. However, success also depends on the rim and tire interface.

Store them in a cool, dry place away from direct sunlight. Because they are pressurized, it is best to keep them in your saddlebag or a dedicated tool roll to prevent accidental damage or puncture.

CO2 cartridges do not have a formal expiration date, but the seals can degrade over many years. As long as the cartridge is undamaged and the threads are clean, it should remain functional for a long time.
