A practical choice for riders who want a compact, ready-to-use puncture inflator with controlled gas flow and on-bike cartridge storage.
The ZEFAL CO2 Inflator Kit combines an EZ Control inflator with an integrated CO₂ Holder, giving you a compact repair solution for road rides, commuting, racing and everyday puncture protection. It works with both Presta and Schrader valves, and inflates tubeless or tubetype tyres without pumping action.
The Z-Flow system lets you regulate the gas progressively by adjusting the black control piece, so you can manage the amount of CO₂ entering the tyre instead of releasing everything at once. That makes it easier to approach your target pressure, while the aluminium and rubber construction keeps the inflator practical to carry.
The holder uses a strap to attach around the seatpost and carries two threaded cartridges plus the inflator in one tidy package. The kit includes two 16 g steel cartridges, and the holder also accepts compatible 12 g, 16 g and 25 g threaded cartridges when you need to replace or change your supply. CO₂ cartridges are recyclable; make sure a cartridge is completely empty before replacing it.

Two cartridges included

Broad cartridge compatibility
