BikeTiresDirect 16g Threaded CO2 Cartridge (6-Pack)

Great value, quality product

I'm fortunate to say that I haven't had to purchase a whole lot of these. However, all it takes is one ride to remind you that you might ought to have a few extras on hand. I use the Portland Design Works Shiny Object inflator. These thread in securely and stay put. They also fit in my small under-saddle bag, which holds a spare tube, levers, inflator, tire boot, etc. I find that these will only inflate a 25c tire/tube to about 80-85 psi, which is adequate to get through the ride. If you happen to have a hand pump and get the tube partially inflated, then these are great at topping off to higher pressure. It all depends on what your tire/tube situation is and what you're willing to carry on a ride.

Tip: Cut a portion of an old tube and put it around the C02 cartridge. These things frost up immediately as they expend their compressed CO2. So, after mounting your tight tire back on the rim of your expensive carbon wheel, it can hurt when your tenderized flesh pulls loose from the ice-cold surface of the cartridge. An old tube will protect your skin and makes the cartridge just a bit less bulky in your saddle bag or jersey pocket.

quickest and simplest way to fill your on road repair

My little saddle bag is too small to carry more than one cartridge and so I tape 2 extra one's to the seat post.

I always carry a pair of CO2 inflators in my under seat bag. Normally I can only find 12 gram size. 20 gram cartridges are too tall to fit in & close my under seat bag. The larger 16 gram just make it. I carry 2 in each of my road & cycloross bicycles. So the six pack was perfect for re-outfitting for the season.

It's gas. Not much else to say.

Great deal on an important item that should last me for a few years.

Anytime, anyone on our group rides gets a flat. I quickly change the tube. Having CO2 available to refill the tire expedites the process.

These are reliable CO2 cartridges that last until you need them.

I've gotten cheaper ones before that turn out not to work when you

need them. These have always worked when I need them.

Love these for when I flat. Does the job of getting me going again

Always keep a couple in saddle bag. Generic name but same quality as more expensive name brand CO2 cartridges. No reason to pay more.

I'm always a fan of threaded versus the container cartridges. Easier to transport. These are a great price and get the job done.

I think their the best Co2 out there. They work every time.

The threaded inflators are the way to go, just screw into a mini inflator. Great price and fast delivery. I care 3 on any time pf ride - mtn, road or gravel just in case.

I use these with a PDW Tiny Object and it works as expected.

I keep a couple of threaded co2 cartridges on every ride. These work fine.

Threaded and works.

The goat heads were out to get me!! These worked exactly as expected! Good deal!

Great idea. The prices have climbed to a ridiculous level at this point.

These cartridges come in handy when a dreadful flat happens. They are of quality and economical to purchase.
