Great For 29ers
These 20g cartridges are rated by Innovations to fill up a 29" mountain bike tire to 43 psi or two 26" tires to 24 psi. These are a lifesaver to have on the trail when you get caught with a flat. They involve much less work than a hand pump and can easily achieve higher pressures. Don't forget an inflator and to replace the CO2 with air once you get home.

These are awesome to take on the trail. Combined with the co2 inflater head this is an easy way to get quick air into your flat without having the wear your arm out using a traditional mini pump. Remember, this is just a temp fix to get you out of the woods. Always let the co2 air back out of the tube and re inflate with a standard pump. Co2 air is compressed and is lighter than standard air so it will seep out over time.
Great piece of mind
- Familiarity: I've used it once or twice and have initial impressions
I used to carry hand pump for mountain biking and they works if you need to pump 10-20 psi but you hand get tired if you need to get 30-45 pis into your tire. I usually carry 2 in my backpack for long rides. You never know when you will need them.
Can never have enough air
Stash two of these away somewhere you'll find them when you really need them.
