Azur CO2 Replacement Cartridges – 25g, Threaded

AZUR CO2 REFILLS: Quick, Convenient, and Reliable Tyre Inflation

The Azur 25g CO2 cartridges are designed for cyclists who need a quick and efficient way to inflate tyres on the go. With a larger capacity than the common 16g cartridges, these are ideal for higher-volume tyres, such as gravel, MTB, and fat bikes, where a single cartridge can provide a full inflation. Their threaded design ensures compatibility with most CO2 inflators on the market.

Key Features:

• 25g capacity – suitable for inflating larger-volume tyres.
• Threaded design – works with most CO2 inflators.
• Fast inflation – quickly gets you back on the road or trail.
• Compact and lightweight – easy to carry in a saddlebag or jersey pocket, each cartridge weighs approx 94g and measures 105mm long * 25mm wide.

Who is this for?

• MTB, gravel, and fat bike riders who need a higher volume of CO2 for a proper inflation.
• Road cyclists running higher pressures who want a single cartridge to do the job without needing a second one.
• Commuters and touring cyclists who prefer the convenience of a quick roadside repair.

Who might prefer a 16g cartridge instead?

• Road cyclists with standard 23-28mm tyres – A 16g cartridge is often enough to reach 90-100 PSI, whereas a 25g might be excessive.
• Weight-conscious riders – 16g cartridges are smaller and lighter, making them preferable for those who want to carry minimal gear.

Other Uses – Not Just for Cycling

While these cartridges are primarily marketed for cycling, CO2 cartridges are also commonly used in non-cycling applications, such as:

• Mini keg and homebrew systems – for carbonating or dispensing beer.
• Airsoft and paintball guns – some models use threaded CO2 cartridges.
• Soda makers – though compatibility depends on the device.

If you’re using these for a non-cycling purpose, always check your system’s requirements to ensure compatibility.
