PRESSURE DRIVE CFH

This bicycle air pump met my expectation in that I needed a system that would satisfy a dual source of filling bike tires. The only down side is because of it's size it doesn't fill a tire quickly using the pump. Over all I like this system.

Pump is good quality but it doesn't hold the pump or co2 cartridge securely enough. I've lost two co2 cartridges already as they slip out of the strap. The pump stays on but sometimes extends and moves around.

Great pump. The Presta valve adapter is at the end of the hase that comes out of the pump. It is set up to Schrader from the factory. Just unscrew the end, and flip it over, then reattach.

This pump has irritated me every time I have used it. The braided metal hose that connects to your stem does not flex easily and makes it difficult to remove from the presta stem. This is a minor issue when you are pumping up the tire, but it quickly becomes a major problem as you realize that the hose end has grabbed your presta valve core and you have lost all your air. A few more inflation and &%$#ing deflation cycles later, and you have finally managed to gently...GENTLY!...unscrew the pump hose without bringing the valve core with it. My advice, make sure you pack a small wrench (your multitool spoke wrench) to crank down the valve core on your new tube before loosely attaching the hose.Screwing the co2 bottle on and off is also real roll of the dice without any practical way to control the flow. Keep your fingers crossed that it engaged the plug properly and you aren't just blasting air with no way to stop it save frantically unscrewing it. I've considered packing a small on/off regulator, but then why did you buy an all-in-one pump like this to begin with?I've also burned through a ring seal on the pump piston after a total of ~2000 pumps. There have to be better pumps out there, let me know if you find one.

The size of this pump is great for taking on a road bike without too much hassle. I've had to use the pump once out on the road and it was a pain in the @ss to say the least. I replaced my tube, pumped up the tire to a reasonable pressure, started to unscrew the pump from the valve and WHOOSH all the air comes out of the tire. Low and behold the pump had unscrewed my valve from the stem! After more attempts than I care to count I finally got the pump to unscrew without losing my valve. I wanted to love this pump, but so far it hasn't been that great.

This is the best little pump I've ever used. I really like the versatility with the CO2 inflator, and the hand pump. Plus, it gets great pressure.

Excellent service! A+++++++

Assez petite et légère, elle ne dérange pas une fois fixé contre le porte bidon.Côté utilisation, c'est un peu long pour gonfler réellement un pneu 700x25 mais ça dépanne bien si là où les cartouches de gonflage sont vide. Pour ma part, je m'arrête entre 5 et 6 bars si ça arrive. Ça reste du dépannage.Et puis le gonfleur CO2 intégrés, c'est top. Une cartouche 16gr gonfle un pneu de 25 a 7.5bars.C'est en tous cas très rassurant de l'avoir en tout temps sur le vélo.

Die Pumpe liegt gut in der Hand und macht einen wertigen Eindruck. Hab nach erhalt ein 26 und 28 Zoll Trekkinreifen (Fahrrad/Autoventil) stramm nach pumpen können.Im Lieferumfang gab es die Pumpe mit integrierten Flexschlauch, einer CO2 Kartusche, eine Halterung und zwei Klettbänder. Eines womit man die Pumpe mit Kartusche oder auch 2 Kartuschen ohne Pumpe an ein beliebiges Rohr befestigen kann und das zweite um die Pumpe fest an der Halterung zu fixieren. Am Getränkehalter angeschraubt ist sie kaum breiter als dieser selbst. Alles in allem ein guter Pannenhelfer für unterwegs.

Excellent well made piece of equipment that is simple and effective in use.

Die Ware entspricht meiner Vorstellung. Man kann sie als normale Pumpe verwenden oder die CO2 Katusche benutzen, damit es schneller geht.

Pump is great, but bought elsewhere as seller cancelled before shipment.
