Innovations Microflate Nano Inflator

This simple and proven design from Innovation changes color from time to time, but the actual design and function remains the same. All you need to do is thread on a CO2 cartridge to the Nano head, then slide the opening of the Nano adapter over your valve. After this is accomplished, just un-screw and back off the CO2 cartridge to release the CO2 into the tube or tire. You can throttle the amount of air flow by twisting the cartridge right/tight and left/loose which is effectively opening and closing the flow. Push on for Presta, screw on for Schrader valves.

Robust nylon construction with metal and brass inner valve parts ensure durability (and reliability) in the field. The Nano is an incredibly simple design and simple in this case means durable and flawless execution of air insertion every time.


  • Simple and durable design
  • Includes one 16 gram cartridge
  • Uses threaded cartridges only
  • Fits most disc wheels
  • Proven winner in the field
  • Tiny profile fits into small packs and pockets
  • Made in USA

The best CO2 pump period. Simple, easy and doesnt waste cartridges.

Pros Simple, small, easy to use

This requires an innertube valve stem to be long enough to stick at least 15 mm above the wheel rim, while installed; so, with a 30-mm deep rim; it needs a valve-stemmed 'tube of 45 mm, or longer. Also, while the IMN inflator is pressed onto the valve stem, the cartridge must be twisted to allow the gas to pass into the innertube; so, keep it threaded loosely-enough to turn it without breaking the valve stem of the 'tube. It can be retightened to retain any unused CO2.

Pros Light weight; small;

Cons May require longer innertubes with longer stem.

This is just a fabulous piece of kit: small, light, easy to use. It does what it says on the tin. Just screw in the CO2 and back it out to release CO2 at desired rate. No fiddling with regulator valves, etc.

I was kind of skeptical of the minimalist design on this, but I had to use it yesterday (after it sat in my seat bag for over a year in pretty severe hot/cold conditions) and it worked amazingly. Real quick to use, made a great seal with the valve w/o any leakage, and filled up the tire almost instantly. This has got to be the smallest option for inflating a spare tube, but nothing is sacrificed in terms of function or reliability. Highly recommended.
