LEZYNE CO2 Bicycle Tire Inflator w/16G Cartridge

Haven’t used it yet, but It came fast and fits in my little pouch nice and snug.

This device is small and simple. Screw on the co2 cartridge, push the valve head on your tubes valve, turn the valve open and you have air. You need two hands to do this, but it comes with a sleeve for the cartridge so your hands won’t freeze. I guess you could use a small amount of air to seat the tube first, but I use a mini pump to do this. I inflate the tire when the valve is in the 6 o’clock position (as Lezyne illustrates in thier instructions). Which is difficult, unless you have something to lean the wheel on. Probably easier to put the wheel on the bike first, put your bike upside down, then inflate. Kinda pricy for the size, but it works and it is well make. Takes up no room in your jersey pocket or saddle bag. I always pack needed items in my jersey pocket as I have lost a couple of saddle bags while on rides over the years.

The dial on this unit provides precise control of flow rate that is far superior to a prior unit I owned that had an unpredictable sliding mechanism that tended to release the whole cylinder of CO2 almost instantly. With the Lezyne, I can start off with just a tiny trickle of flow to get the tube fully seated and then open up the valve to finish the job.

Finally, a C02 tube inflator that works. Completely worth the extra few dollars. Tried three others that were terrible. The Lezyne CO2 inflator performed exactly as promised in the video. The entire process took less than 1 minute. It took longer to open my bike kit than it took to attach the CO2 cylinder to the Inflator, open the tube stem, insert the stem into the inflator, turn the flow control to open, fill the tire, remove the inflator, close the stem. The tube was fully inflated.
As a side note…one thing I did learn during my research is that the air from a CO2 cartridge will seep out overnight. Once you get home you need to deflat the tire and inflate the tire with air from a regular pump.

What I like is the push-to-connect feature. I had another inflator that requires screwing it to the valve (I only have tires with Presta valve), but then every single time I remove it (after inflating it), the inner core stem would come off and deflate the tire again (that’s why I always carry a portable pump).
The nice thing of this inflator is that you push it to the valve and inflate, then to remove you pull it out. It maintains a good seal and let you inflate the tire with good control. Since to remove it you don’t need to unscrew anything, the inner core stem remains in place.

Nach einigem hin und her, ich wollte unterwegts bei Luftmangel im Reifen nicht mehr mit diesen kleinen Pümchen arbeiten, habe ich mir diese Pumpe zugelegt. Ich kann nur sagen: Super! Ich habe sie zunächst zuhause getestet, um nicht ein funktionsunfähiges Ding dabei zu haben wenn unterwegs mal wieder Luftmangel herrscht. Die Pumpe passt perfekt an ein Presta-Ventil, (=Sclaverand oder französisches), wie es mit mit einem Dunlop Ventil aussieht konnte ich nicht testen, ich habe ausschließlich “die dünnen langen” in Gebrauch.
Das Einschrauben der CO2-Patrone gelingt mühelos, es ist sofort dicht. Besonders gefällt mir das Regulierventil, mit dessen Hilfe man die Auffüllgeschwindigkeit sehr fein regulieren kann. Das geht so gut, dass man es schon fast bedauert wenn der Reifen schon wieder voll ist. Diese CO2-Pumpe ist inzwischen mein Dauerbegleiter wenn ich mit dem Rad unterwegs bin. Ist leicht zu verstauen, auch eine Ersatzpatrone findet leicht ihren Platz, wiegt nicht viel und was am wichtigsten ist: es funktioniert.
Würde ich sofort wieder kaufen, klare Kaufempfehlung. Gute Handluftpumpen für unterwegs sind auch nicht billiger allerdings muß man sich mit der CO2-Pumpe gar nicht anstrengen und es geht damit auch viiiiel schneller. Viel Spaß beim Pumpen!

Inflated tire quickly and easily when I needed it. An air pressure gauge would be a nice addition.
