Simple yet brilliant design from Innovations means no more fumbling about to use a CO2 cartridge. Simply thread on a cartridge, slide the mouth of the adapter over your valve and un-screw to release the CO2. You can throttle the amount of flow by twisting the cartridge right/tight and left/loose effectively opening and closing the flow. Push on for Presta, screw on for Schrader valves.
Durability guaranteed through tough nylon construction with metal and brass inner valve parts. Super-duper bare bones design in a lightweight and durable package make this the undisputed field champion for reliability. The Nano is a staff favorite and the choice of many Pros.

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.
