Which CO2 inflater is best?(8 posts)

Which CO2 inflater is best?Nessism
May 10, 2002 5:27 AM
Looking to speed up my flat repairs and want to pick up a CO2 inflater. Economy of use is important.

From what I've read, 12 gram cylinders will provide 90 psi on a 700x23 tire which should be sufficient to get home. True? Also, someone mentioned here that bulk cylinders are available from Wallmart for cheap?

Looking for input.

Yes, you can buy 12g cylinders at walmart for alot cheaper than you pay at your LBS, look in the sporting goods section where they have the air gun stuff...I like the innovations second wind (I think they have a new model out)..because it is also a mini pump..I pump the tube up a little bit before using the CO2 to make sure the tube is in place correctly..they go for around $20.

I'm using the Innovations Ultraflate CO2 inflator on my MTB and road bike along with the 12g unthreaded cartridges. These are readily available at Walmart for less than $10 for a box of 25. I carry 3 cartridges: 1 inside the body of the inflator, upside-down so as not to pierce the CO2 cartridge, and 2 others taped to the outside of the body of the inflator. These 2, in combination with the CO2 inflator tuck-in very nicely at the downtube/seattube/BB intersection and are held in place with a velcro strap.

BTW, I also carry a Crank Bros Power mini pump, just in case.

Awesome little gadget. I carry one cartridge in the inflator and two more, plus tire lever, held to the outside with rubber bands.

You can get unthreaded cartridges anywhere that sells air powered guns. I go to a nearby Army/Navy store and got 25 for $15.

As for the cartridges...I bought the Walmart 12 pack myself. But a often do you have flats??? Personally, I spent a few bucks and bought several of the 16g threaded cartridges. These will take your 23mm tire up to 120. I carry four at a time.

Was at wal-mart yesterday, you can get 5 cylinders for 2.97 or 25 for 11.97. I am going to go pick-up the second wind this weekend I am hoping if I can get 20-30 psi from the mini-pump and top it off with the co2. I dont want to just "get home" I would like to finish my rides.

I got a box of 25 at Academy for 7.98. I actually bought two boxes.

Make sure you get a non-threaded CO2 infaltor. The threaded inflators/CO2 bottles are the biggest ripoff since the titanium water bottle cage!

I switched over to co2 last July after becoming very frustrated with messing with frame and mini pumps and occasionally snapping off the long valve stems needed for my Rolf wheels on my Klein. The Innovations Ultraflate is the only co2 system my LBS carried so I purchased one.

As you mentioned, a 12g cartridge will get a 700x23 tire up to 90 psi. I pack a small Torelli mini pump attached to my bottle cage. I practiced in my garage and 50 strokes with the Torelli will get me up to around 30 psi then I finished off with a 12g co2. I also use the mini to mount my tire without waisting any co2.

I pack the Ultraflate loaded with one cartridge and two extra cartridges in my seat bag. If for some reason I should ever have more than 3 "f's" on one ride I have the Torelli mini, which will give enough air in to get me home.

The advantage of the 12g cartridges is that you can purchase them in bulk at most sport shops as they are the same type used for pellet guns/air rifles etc. I think I paid $12.00 for a box of 15.

A 16g co2 will get you up to 120 psi. The Ultraflate will work with a 12g or 16g cartrige. If you don't mind forking over the extra money (depending on how many flats you get) you might look into a Innovations Air Chuck. It uses 16g cartriges and it works like the nozzle on a gas station hose. The downfall is the 16g run about $2.00 a piece.

Odd as it seems, when I finally switched over to co2 after a lot of consideration, I have had a total of one "F" (can't say that word) since July. By the time I went to use it I had forgotten how it worked and went though 2 cartridges until I figured it out.

Co2 makes changing flats easy, I'm happy I switched over.
