CO2 Inflator Kit with 16g/ 25g CO2 Cartridges - Presta & Schrader Valve Compatible - CO2 Bike Pump for Road and Mountain Bikes

The valve component seems well made; no quams. As for function, I haven't the need to use it yet.

The wheel/tire set I used this on was a DT Swiss R460db 700c rim with a Vittoria Zaffiro Pro Slick 25c tire and TPU inner tube. When I used this inflation system, I was indoors with an air temp of 60 degrees F. I screwed the cartridge into place at the bottom of the nozzle. No problem. As with anything presta nozzle, the one on this system pressed pretty easily into place over the valve. When I turned the activation lever, the nozzle very briefly leaked a bit of air but almost immediately sealed into place. The tire requires inflation between 100 and 130 PSI. The system filled my tire to just over 100 psi with a more to spare (though I doubt it would be near enough for a second tire). When the CO2 expanded from the cartridge into the presta valve, I got the expected thin icy layer over the cartridge (thanks for the sleeve!) and at the connection between the valve and the nozzle. The rubberized material in the nozzle contracted and gripped the valve to the point I couldn't pull it off. But the and of the nozzle is made to turn freely, which allowed me to essentially "unscrew" the nozzle from the valve with zero loss of air. I used this to inflate my tire in my living room before needing it for the first time on the road. Based off that, I'm confident that it will work great if I need to change out a tube on the road.

Is as advertised.

This is a great value CO2 inflator kit. It's compact and lightweight, so I can easily carry it in my bike frame bag for emergencies. It works with both Presta and Schrader valves, which is super convenient. For the price, you can't beat the peace of mind it provides on a long ride. Highly recommended

Handy little tool you can carry along on bike rides. Works much better than hand pump.

I tried it in the garage and seemed to work ok. Out on the trail this evening, tried two cartridges but was left stranded on the trail.

I've used this thing to get my nephew off the side of the road when his spare was flat. Put one in my bike and all other vehicles I drive alot. Buy it.

This inflator works great. I have used it to fill bicycle and motorcycle tires. It probably works well with car tires as well but I haven't tried it with those.

Prodotto buono e pratico

Perfecto

Il prodotto è risultato difettoso: ho bucato una gomma e non ha funzionato nel rigonfiaghio, a causa o di una difettosità sul rubinetto oppure perché le bombole erano vecchie e scariche. Ho usato due bombole ed entrambe non hanno gonfiato la gomma. Prodotto cinese di scarsissima qualità, se non fossi stato in viaggio con una persona in possesso di un prodotto diverso non avrei potuto riparare la foratura.

Despues de probar otras marcas, esta cimple con su funcion, es decir abre y cierra perfectamente.

Funktioniert sehr gut
