Item # LED0011

Minuscule and mighty.

Fast air combined with light weight in a tiny package are the reasons why everyone loves using CO2 cartridges The promise has amazing hedonic value and seeing a CO2 inflator in action for the first time is equal to the wonderment of seeing a magician saw someone in half for the first time. The Lezyne Trigger Drive CO2 Kit gives you the dream.

What Lezyne's design has going for it is not only the small size, or the light weight (claimed 26g), but everything. Lezyne has taken a hard look at the harsh reality of tiny inflators, and eliminated the weaknesses. The chuck is made of machined aluminum for both minimal weight and great durability. The chuck is made to join the cartridge to the valve at a right angle, so it can fit into the recess on disc wheels. The chuck itself threads onto the valve, be it Presta or Schrader, so none of the precious CO2 leaks out. And the CO2 is released via a spring-loaded trigger so you can shoot a little air in to seat the tire, then inflate the tire in slow bursts.

  • Familiarity: I've used it once or twice and have initial impressions

Works great. Very sturdy yet small and compact.

Always have mine!

  • Familiarity: I've put it through the wringer

I always carry this thing in my Dakine Hot Laps bag along with the co2 cartridges. Super small and doesnt take up much space at all. Let me know if you have any questions on how to use this.

No more wasted CO2

  • Familiarity: I've used it several times

This little trigger makes fixing a flat super easy. No more wasted CO2 going into the air around you as your tube stays flat. Screw the CO2 cartridge on, then screw the trigger onto your valve, then push the trigger and watch it inflate. Unscrew everything, put your tire back on and you are good to go!

Simple and Easy to Use

  • Familiarity: I've put it through the wringer

Just like the title says, this inflator is simple and easy to use. I would recommend this as an alternative to a hand pump. Make sure to pick up some extra co2 cartridges and you'll be set!

Small, light and gets the job done

  • Familiarity: I've put it through the wringer

You won't be disappointed with this inflator. It's very small and works really well. always comes through when i'm in a pinch

Compact and easy to use

  • Familiarity: I've used it several times

Be very careful of the O-ring, when it falls out the unit will not operate. No bells and whistles here.

Peace of mind without taking up space

  • Familiarity: I've used it once or twice and have initial impressions

Nice to have a pump I trust without having to strap it to my frame or carry a second bag just to fit it. This thing is tiny and that's exactly what I wanted.

Gets it done

  • Familiarity: I gave it as a gift but have feedback to share

I got these for my brother who does some high school level mountain bike racing. He feels that they are adequate for the job. When you don't need the best thing on the market but good enough to get it done quick and easy, these are great. I got him a bunch of extra cartridges as well so that he isn't out of luck when he gets a couple flats per race.


  • Familiarity: I've used it once or twice and have initial impressions

Piece of crap, buy something else. nothing like getting a flat and pulling this thing out and straight up not working.... spring not compressing, wouldn't even screw on....I guess I should have tried it before putting in my jersey...

O ring falls out

  • Familiarity: I've put it through the wringer

I like the concept, the weight and the convenience. But every time I use it, the O ring comes unseated. I've tried a bit of lubricant, but to no avail. I'm thinking it'll be lost eventually, and the inflator head would be useless.

Same problem here. Without the o-ring, it will not function.

Quality is key!

  • Familiarity: I've used it once or twice and have initial impressions

This is a key piece when you need it and having a quality one is key. I bought several cheapy one before and it almost left me stranded if not for a manual pump! The punction tip is key as my last one broke! The nozzle is also and must offer an easy control and this one has it. I've only used this 2x but so far so good. I'll love it when I hit 4 or more saves..

Oh and besure to have the right Co2 size cartridge for your tire.. 16oz is minimal.

All business.

  • Familiarity: I've put it through the wringer

Great inflator. Perfect blend of smart function and small size. I have two other inflators (Genuine Innovations) which I like, but this Lezyne has become my favorite. I really like the built-in press to inflate feature. No twisting, no bulky trigger and great control. It looks good and it has worked great.


  • Familiarity: I've used it once or twice and have initial impressions

A must have - I have gotten over 10 years out of my old trusty inflator, until it's failure to perform last flat - RIP little dude ;) Good things come in small packages, as this is sweet. Compact, small, and machining is A+. Only takes threaded CO2 cartridges, and any threaded cartridge will work. Also comes with a sleeve for so the cartridge doesn't freeze your hand while inflating - that also doubles as a nice touch to keep the noise down while in your seat bag. A must have, and at such a compact size - worth the extra gram in your pocket :)


Will this take any c02 cartridge, or only...

Will this take any c02 cartridge, or only Lezyne?. Do you thread the chuck into the valve first, then crew on the cartridge?

Best Answer

Greetings - this will accept any threaded C02 cartridge; but will not work with non-threaded :) And correct, thread the unit onto the CO2 first, then inflate - easy peasy :) Works awesome, just hope we all don't have to use it that often :)

Perfect for a quick road fix

  • Familiarity: I've used it once or twice and have initial impressions

I almost didn't buy this CO2 inflator because despite the sleek looks and compact size lots of reviews from other sites complained of the trigger being difficult to activate which kind of defeats the purpose of having it in your repair kit. I suspect some of the problems people elsewhere have had may be due to a poorly machined inflator because with my small, weak hands I'm able to use this quite easily. Mine came with a protective freeze sleeve to fit over the CO2 canister to keep your hands from getting cold but with my small hands I still have to press against the round butt of the canister to activate the trigger so I keep my gloves on for that step. Very easy to use, great aesthetics, fits easily in my small Lezyne Micro Caddy Saddle Bag. FYI one 16g CO2 canister will inflate a 700x25 road tire to ~90 PSI, enough to get you back home safely.

Quick and Easy

  • Familiarity: I've used it several times

This CO2 System is really intuitive and easy to use. It inflates tires quickly. I've used it on my 29" mountainbike and one cartridge get's you up to pressure quickly. Like most things Lezyne this is well constructed and I have little doubt about it's long term durability.

beautiful, functional

  • Familiarity: I've used it once or twice and have initial impressions

I must admit, while reading reviews for this inflator, I was torn between the beautiful design and good reviews compared with the mediocre design and glowing reviews of the similar Genuine Innovations product. Eventually the desire to have a CNC'd block of beautiful aluminum won out, hoping it would work when I needed it to.

Turns out it does work, and well. No complaints, does what it says it will, inflates your tires in a pinch, I've had to use it a single time and it did it's job. No complaints. Recommended. And I love that it looks beautiful and solid in my wedgie bag. And no messing with crappy hand pumps.
