Lezyne Trigger Speed Drive CO2 Inflator - Black

I had been carrying this unit in my seat bag since last year and finally hadoccasion to try it out. For so small a tool, it is everything they say it is. The15g threaded cartridge screws securely to the unit and it grips tightly on the valvestem. You can hold the unit on the valve while turning the knob to precisely meteout air to the tire maintaining control over how fast the tire inflates. No moreheart-in-mouth moments as compressed air zooms into your tire to the point ofbursting within seconds. I will be replacing all my old inflators with this one soeach bike has this unit. The price is worth the peace of mind knowing I wont burnthrough multiple cartridges before I get it right next time I flat. I can alsoimpress my riding buddies should the need arise ... MoreI had been carrying this unit in my seat bag since last year and finally hadoccasion to try it out.

Best Co2 inflator

Co2 cartridges are the best thing to come along for cycling. They are a must have in any saddle bag or pack. What makes this better than the others is the ability for the cartridge to be pierced and then remain FULL if you don't empty it. Nothing worse than only having one or two cartridges and having to waste it by only using a little bit is silly. This setup lets you thread a cartridge, then use just what you need (Maybe you need to add a little air to an empty tube before putting it into the tire) and still the cartridge stays full, even a month of two later!! IMHO this makes this one of the best. Just found out by needing to top off a tire on the road and found my cartridge was already pierced from last use.. I thought I was hosed..but nope.. Great buy.

Fits in a small space

Excellent product, fits in a small space and is lightweight.Fits perfectly in a small saddlebag. It has the advantage of being CO2 adjustable and includes an insulating jacket.

Great Size and Looks Promising

CO2 cartridges have continued to become the core of any cyclists bag kit. The drawback is of course once the break the seal, it's a use it all or it goes to waste thing. I am hoping this one helps to eliminate that. Had a chance to try this out this past weekend on local group ride. one rider got multiple flats and had to "add air" several times on our ride. One 16g unit worked several times. So, Yes it does do as promised.PROS: Easy to Use, Lightweight, Keeps Air In Cartridge, Super Compact SizeBEST USES: Road Bikes, Mountain Bikes

Great purchase

Wanted a CO2 inflator with a regulator/valve. Unfortunately wasn't much to choose from that was still in stock but this one fits the requirements. Good quality and comes with a CO2 canister.

One of the best

The best of the bunch. I had purchased the Serfas brand inflator and promptly replaced it with this one. Easy to use with enough nozzle to provide leverage when screwing on the CO2 cartridge. The positive feedback on the application also sealed quickly after use. The cartridge pressure kept intact after a partial use even after several days in the seat bag. This is a "must-have" item for any seat bag. Use the larger cartridges for MTB tire inflation.PROS: Lightweight, Easy to Use, DurableBEST USES: Road Bikes, Long Rides, Mountain Bikes, Commuting

Small and efficient

A great little device. Although I have struggled when there is no initial air in the tube. This sounds ridiculous but I could only get it to work when I put a small amount of air in the tube from a pump to push against the valve (which is a pain having to carry a pump as well). The gas just removes the vigorous pumping stage.Furthermore the thin cover is not enough to keep you from freeze burn. I would strongly recommend a thicker case or using gloves!

Well Designed and Engineered

Had a chance to use this when I got a flat last week and I was really impressed with the product. I've never used a CO2 inflater before and kind of expected to lose lots of pressure but the Lezyne trigger worked wonderfully. The trigger sealed perfectly to the presto valve which never seems to happen with traditional pumps. No pressure was lost at all! The only problem I had was that towards the end of inflating the tube, the trigger became so cold that it pretty much froze up and stopped inflating. Next time I have to do this, I will stop halfway through inflating and let the trigger warm up and then continue. The 16g cartridge inflated a 700c x 23 tire perfectly, maybe not to full 110psi but very close. I still had a little left in the cartridge but I was happy ... MoreHad a chance to use this when I got a flat last week and I was really impressed with the product.

I still had a little left in the cartridge but I was happy with the pressure and just wanted to get home. All in all, the Lezyne inflator worked very well. I didn't expect it to work as well as it did. It seals perfectly to the presto valve and is easy to control the pressure. It is very well made and only takes up as much room as absolutely necessary and is aesthetically pleasant as well. Very impressed and recommend every cyclist have one in his bag because a puncture is positively coming your way at some point.

Works perfectly

Having muddled through with a cheap mini pump that couldn't get enough pressure into the tubes, I decided to go with this CO2 inflator. I wasn't disappointed - having used it twice now, it is so simple to use and inflates tyres within seconds. Just place the inflator onto the valve and twist the dial. I was worried that CO2 would prove troublesome, particularly given the one-shot nature of cartridges, but if you realise the CO2 isn't going in you can easily close the dial and put the inflator on properly. 10/10
