    Is a 16 gram CO2 cartridge enough to fill a 29er?

    Thinking about starting to carry CO2. I have 16 gram cartridges that I use on the road right now, and I was wondering if they will fill a 29x2.2 tire. I need at least 35 psi.

    FWIW tire will be a geax aka tnt.

    Nope. You need a larger size.

    You can get cartridges in the 24 oz. size as well. As to weather or not it will be enough, there's too many variables because there's so much difference in volume from tire to tire.

    Going to try out the Big Air Can after I run out of the smaller guys. Should work with the air chucks of the smaller ones too. Seems like it would take up a bit more space though. I'm a little put off about their 85 degree disclaimer though. I normally ride at 85+, especially in the summer as I'm sure everyone else does too. Filling my tires with combustible propane is a little worrisome, thank god I don't smoke!

    You guys carry a gauge as well? If so, which one? Hope this wouldn't be considered thread jacking

    I prefer the 20 or 25 gram cartridges over the Big Air. A bit more oomph for reseating burped beads and plenty of air for your needs,

    Check out the inflation chart here:

    I get paid 3 every time I post on MTBR.

    Any hookups for bulk 25g threaded cartridges? I've been buying cartridges in box of 30s to cut cost...

    Just checked the prices on the 25 gram cartridges.

    And then I went shopping for a pump. I got a topeak mini morph. I have a road morph for the road bike that has served me well. Probably just going to stick with the pump.

    I was thinking I would switch to a patch kit and co2, but i will just stick with the pump and tube method. Hopefully with my chunky new tires I wont flat much anyway.

    let me know how those work out for you. They seem like they may be too long for a saddle bag which is my way to carry them, but they may work just fine.

    took me 2 to inflate my tubeless and get it to seal up. I used COs bought from walmart, works well enough for me

    Amazon's got a bunch in various quantity options.

    This should be a search for 16 and 20 gram bicycle inflator stuff: Amazon.com: co2 cartridges - 20 Gram or 16 Gram / CO2 Pumps / Bike Pumps: Sports & Outdoors
