X-Tech CO2 Cartridges

When a flat tyre strikes mid-ride, there’s no time to muck about. The X-Tech CO2 Replacement Cartridges offer a fast, hassle-free way to get your tyre re-inflated and rolling again in seconds. Each 16g cartridge delivers a powerful burst of compressed air, giving you enough pressure to seat and inflate most road, gravel or MTB tyres with ease.

These cartridges feature a standard threaded design, making them compatible with most common CO2 inflators. Their compact size makes them a smart choice for tucking into a jersey pocket, saddle bag or storage canister, so you’re always prepared—whether you’re commuting, racing or out for a weekend gravel ride.

Who is this for?

This product suits riders who want a lightweight, compact backup plan for dealing with punctures while out on the road or trail. Whether you’re a roadie who wants to avoid wasting time, a gravel rider dealing with unpredictable surfaces, or a commuter who needs a no-fuss inflation option, this is a solid bit of kit to have on hand.

Who is this not for?

If you prefer using a mini-pump or don’t like the single-use nature of CO2 cartridges, these probably aren’t for you. Likewise, if you’re after high-volume inflation for fat bikes or running tubeless setups that require a longer blast of air, you may need a larger canister or a compressor-style tool instead.

Why we love it

It’s the kind of product you don’t think about—until you need it. We’ve used these on roadside punctures and been back riding in under a minute. The consistent pressure delivery, reliable threading, and ease of use make it a no-brainer addition to any repair kit.
