Why Keep the MSW CO2 Cartridge in Your Seat Bag?

The MSW CO2-20 Threaded Cartridge delivers fast, reliable on-demand inflation when a flat strikes miles from home. Each 20g threaded cartridge threads directly into MSW inflator heads and is compatible with most major brand CO2 inflator systems, giving you flexibility across your gear collection without committing to a single ecosystem. One cartridge provides enough volume to fully inflate a road, gravel, or mountain bike tire, getting you back on the road in seconds rather than spending several minutes pumping with a mini pump.

Lightweight and compact enough to stash in a seat bag, jersey pocket, or tool roll, the CO2-20 is the inflation backup every rider should carry. The threaded design provides a secure, leak-free connection to compatible inflator heads, ensuring consistent pressure output every time. Stock a few cartridges for longer rides or multi-day adventures where multiple flats are possible. Compatible with Presta and Schrader valves when paired with the appropriate inflator head.

FAQ

Will a 20g cartridge fully inflate a road or MTB tire?

A 20g cartridge is typically sufficient to fully inflate a road tire (23-28mm) to riding pressure and will get most MTB tires close to usable pressure. For high-volume MTB or gravel tires above 2.0 inches, you may want a second cartridge as backup.

Are these compatible with all CO2 inflators?

These cartridges use the standard threaded CO2 design and are compatible with MSW inflator heads and most major brand threaded inflators. They are not compatible with non-threaded or puncture-style inflators.

Can I save a partially used cartridge for the next flat?

Once a threaded cartridge is engaged with an inflator head and punctured, the remaining CO2 will escape if the inflator is removed. Plan to use the full cartridge volume in a single inflation session.

Best For

Road, gravel, and mountain bike riders who carry a CO2 inflator as their primary or backup flat repair system. Ideal for racers, long-distance riders, and anyone who wants the fastest possible flat fix on the road or trail.
