Question: Only 1 cartridge serves to fill a rubber 2x1.95?
Document: This purchase was to have an extra supply. The  cartridges work as expected and fill a tire so the bike can be ridden.
These fit in the sleeve and thread easily, put out a good volume of tire fill, and the price was great.Seller shipped fast too. Thighs is the deal! !
Use these on my Portland Design Works Shiny Object and they work very well.You just need to be careful when you are threading the cartridge into the valve of your choice so you don't cross thread them.
Got these cartridges to use with my CO2 inflator in case I get a flat while mountain biking. They thread right up to the nozzle no problems. Make sure to place a small drop of 3-in-1 oil in the screw-on nozzle to keep things lubricated and prevent the o-rings from drying out.Cartridges arrived quickly and are much more price effective than buying the name brand ones...a good buy!
got my product in just about one day of purchase! only reason why I didn't give it 5 stars is because I was under the impression that they came in a product box not individuals! it was packed good but now I have loose CO2 tanks all over my room! !
Works exactly as stated. No problems or errors. I was able to hold the remainder of the container until next use.
Work as you would expect in threaded nozzle. If ya gotta have flats on the road these are good life savers.
What can I say? They work great, arrived quickly, and didn't cost much. If you need CO2 cartridges to fix bicycle flats then these can't be beat.
Things work beautifully, all the threads appear good, my only complaint is that they were shipped with packing peanuts in a USPS small flat rate box, making opening a pain, and now I have to store them. That's life though.
They work well for me.
