CO2 Bike Tire Inflator – Quick Push-Button Release, Fits Presta & Schrader Valves, CO2 Bike Pump or 5X 16g Threaded CO2 Cartridges

I LOVE this thing. I bought a 2nd (and will probably buy a 3rd) just in case they stop making them. The button-design is SO superior to the dial versions. I CAN'T stand those--they are so hard to control when your hands are sweaty and you have to kind of hold the bottle with one hand and turn the dial with the other. And you better hope you it doesn't slip out of your hands because when you stop to fix your flat all your sweat starts running down your arms and getting on your hands. And if the dial is open when it slips and is still connected to your (presta) valve, or you panic when the bottle starts freezing to your hand and you let it go, you just have to pray that the open dial valve doesn't over-inflate your new tube and pop it. The button version is SO MUCH BETTER than all those dial ones--I don't understand why these so are hard to find, esp. when they are a good & well-machined as this one. The screw-down to the presta is solid/easy and you only need one hand to inflate, and once you get tube close to your pressure you just give the button bottle quick taps/bursts to get up to your desired pressure.

Works great as a backup while out riding.

This adapter works great! I used it to pump up my tyres after being stuck out on a ride. The button works perfectly and the built quality is almost impeccable. Just a not to new users, you have to screw the head into the valve to create a seal. It is not press fit.

Works well though one somehow got it's threading messed up and now won't hold cartridge without leaking. Other one still works fine

I bought 2 of these (after my son had a flat tire at a race) for my sons to use for mountain biking. They are light weight for races and the cozy makes it so their hands don’t get cold using them! Great option for my peace of mind while they are racing or just riding 15+ miles in the mountains.

I am surprised how well this holds pressure. even with a tank connected for several weeks I haven't noticed any leaks. I put it inside a Ziploc for several days as a test and there was no noticeable expansion. excellent value!

Hard to say as I carry this for emergencies and not daily use. But it is compact and appears to be of fine quality.

Used once on the road and found this design easier to use than my last one. The push button operation is the way to go.

Produto de excelente qualidade

pretty good, must wear gloves....

Aucune perte d’air en vissant ou dévissant la buse à la valve du pneu, .Important de vérifier la pression d’air du pneu Je recommande 🌟🌟🌟🌟🌟

Good material, works good and compact

Worked fine with first cartridge but not on next two, not sure what is wrong with it but very disappointed
