Azur 16g CO2 Replacement Cartridges

Designed for cyclists who value convenience and speed, the Azur 16g CO2 threaded cartridges are a reliable choice for quick tyre inflation on the go. Compatible with most inflators that accept threaded cartridges, these compact canisters are ideal for mid-ride top-ups or emergency repairs.

• Contains 16 grams of compressed CO2 per cartridge
• Threaded design suits most inflator heads
• Lightweight and compact – easy to stash in a saddle bag or jersey pocket
• Inflates a standard road tyre (700x23c) to approx. 100psi
• Requires a CO2 inflator (sold separately)

Why choose 16g instead of 25g?

The 16g cartridge is the right size for road bikes and smaller-volume tyres. It gets the job done without excess weight or waste. Larger 25g cartridges are often overkill unless you’re running higher-volume tyres (e.g. MTB, gravel), and they take up more space in your kit.

Who are these cartridges for?

Best suited for road cyclists, commuters, and triathletes who want a fast, no-fuss inflation solution. They’re perfect for riders who already carry a CO2 inflator head and value space-saving essentials.

Who aren’t these cartridges for?

These aren’t ideal for mountain bikers or anyone running high-volume tyres (e.g. fat bikes), as 16g may not provide enough pressure or volume. Also not suitable for those who prefer the control of a manual mini pump.

Why we love them

They’re small, simple, and do exactly what they’re supposed to. We use these on our own bikes – they’re especially handy during for on the run repairs when every second counts. No need to carry bulky gear – just a quick twist, inflate and you’re rolling again.
