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.
