CyclingDeal 6 or 12 or 20 or 30 Packs x 16g Threaded CO2 Cartridges Refills for Bike Bicycle Pump CO2 Inflator Heads - Great Refill for Mountain Or Road Bikes Tires

I bought this for my fluval co2 setup. I was worried it wouldn't fit. It fits perfectly and I can use it with my fish tank. This was a great buy and much cheaper than most other brands. The canisters are very pressurized and work well. Easy to use.

Very disappointed. I’ve used 3 out of the box, and 2 of them had NO air! It was a box of 30, so I used a postal scale to weigh the remainder. I found one more that weighed 1.5 ounces (empty), the rest varied from 2.0 to 2.2 ounces. So there were 3 defective cartridges out of 30. Luckily this didn’t result in me being stranded, but buyers beware, weigh them before you pack them.

Hey, it’s a tiny can of compressed gas, so it’s pretty foolproof. I use them for re-inflating 700x25 tires when I have a flat mid-ride. Works every time. Each cylinder will inflate the 700x25 tire to a little over 120 PSI, so they are really firm. When I use a floor pump, I usually stop at about 110 PSI.

I figure CO2 cartridges are a generic commodity, so I always shop for the least expensive. That's why I selected these. I haven't used any of them yet (no flat tires) but I can confirm (1) quick shipping (2) box came with all 20 cartridges as promised (3) they weight exactly the same (58 grams) as my other brand unused cartridges and (4) their threading fits my CO2 inflator just fine.

Opened up the box and it only had 19. It was missing one. Paid for 20 and only got 19.

I've tested one of these canisters, and everything seems in order and arrived in a reasonable time. I'd recommend them if this is a product you're searching for.

Good value, good condition, works correctly. Easiest system to use for emergency bicycle tire re-inflation. Effortless to use and simple to carry.

So far so good but I’ve only had to use one. Great price for the amount I received. Will buy again. Filled up my road tube easily.

Bought these not for bicycle tires but for a Growler-Werks Pressurised Ukeg. The only difference was the screwed thread on these but made no difference worked fine in the Keg and are considerable cheaper than buying them from the usual suppliers. Would definitely recommend
