Hope you have this staple in your bag when you get a staple in your tire! Reasons I carry an inflator 1) I commute so I don't want one more thing to have to take off my bike when I park it on the street. 2) My bike frame is already so small, I'd have to plunk down to get an effective pump.
I have 3 of these Trigger Drive inflators. For the first 10 or so uses, they work great. After that, the rubber O ring that seals around the valve stem starts pulling out and you lose the CO2 you are trying to put into the tube. I have put in Lezyne replacement O rings, but before long the same thing happens again. I have since purchased 2 of the newer Lezyne Control Drive inflators. These units seem to correct all the problems with the Trigger Drives. The seal around the valve stem is securely held in place by a threaded cap. The Lezyne Control Drive also has a knob that you turn to allow the CO2 to enter the tube with precise control. In my opinion, the Control Drive is a far superior design that I hope will continue to be reliable over time. I have used the Control Drive about 10 times now, and I will post a review for it when I have used it a bit longer. Lezyne makes good stuff, but I suggest you take a look at the Lezyne Control Drive instead of this Trigger Drive model. I have bought all 7 of my Lezyne pumps and heads from Western Bike Works. They stock the Control Drive as well as this model.
I get controlled inflation with this beautifully machined inflator head. Just push back the sleeve when you are ready for a little or a lot of co2. Handy when making sure the tire bead is seating properly and the tube is not being pinched. Works with presta or Schrader. I enjoy good quality tools this lightweight and elegant design is a pleasure to use.
I own several inflators and found the Lezyne to be the best. The screw on to stem feature allows for better control and a higher psi per 16gr cartridge. I was only able to get 85 psi out of my other inflators , but Lezyne would get my 700cx23 tires to 95psi
It doesnt get much easier than this. Easy to use and it doesnt take up much room in my seat bag. It is a single use system don't try to extend the life of the CO2 cartridge. As all Lynzne products very well made
Simply the best inflator I have used. The valve is efficient and precise and doesn't hang up or stick as I've experienced with comparable products. I own several. BTW I use sections of old road tubes as sleeves on the cartridges to protect from the cold.
I carry the Lezyne CO2 Inflator as an effective tire inflation method. It is precisely what I was seeking lt weight, small, & facilitates smooth, quick, & controlled inflation or topping-off of tires.
I have one of these on both my bikes. I love them. They screw onto a presta valve and is inflated by pulling the valve stem assembly toward the co2. Clever design. Works great. I had one that seemed to freeze over the winter. Otherwise. I would have rated 5 stars. These type of co2 inflatord are all pretty much the same. I'm trying other ones now. But there really was no reason to switch. These work great.
I love this thing.. I bought 3 of them. I keep one on each bike, and a spare. Works great on presta and schrader valves. I love it and use them all the time.
Put a little chain lube on it. it works better.
In the quest for a compact tool this CO2 pump head seemed the best choice. It is a well crafted, solid, efficient functioning unit which takes up little room in my tool bag. There is no need for any other pump head unless you choose to use threadless cartridges.
