MSW  20 g Threaded CO2 Cartridge

This cartridge contains 20 grams of the finest organically raised, non-GMO, fair trade CO2. Seriously it's a threaded CO2 cartridge. If you get a flat out of the road, it's this, a hand pump, or you are in Reebok mode (walking). Me? I'm lazy, I carry a CO2 inflator and a couple of cartridges. Smaller and lighter than a pump and a lot easier than walking a couple of miles to get to the bike shop to fill my presta equipped tire after a flat. (Yup, been there, done that, and I have never forgotten an inflator since!)

Works well compressed air is best for fast on the go tire jobs. Made for a 29er leaves some air left over on a 27.5. never used it on a completely flat tire just more or less touch up air to keep me going on the trail. Don’t think it’s a full replacement for a bike bump. They can get heavy after having three or more. Good luck ride on!!

Product as described, packing job absolutely comical. there were 3 CO2 cartridges tossed into a box sized for a size 15 pair of adult shoes with a paltry amount of packing paper. I'm surprised the cartridges didn't fall out. I could hear them jingling around when I picked up that package. These are tough items, and I never felt they were in danger of exploding, but that was a lucky break, especially with UPS as the shipper.

I usually keep one or two cartridges in my saddlebag for roadside flats. When I mounted a new set of tubeless tires, I couldn't get them to seat on the rims. Using one of these on each tire was the ticket.

Great price point, and have purchased many of these. These CO2 cartridges have saved me multiple times on the road!

Comes in handy!! Had a flat on a ride. Thanks to this device I was able to fix it and continue on.

These things are practically magic. Saved me hours of pumping by hand.

I have not had to use it yet, but it should do the job.
