CO2 buy or not to buy?(10 posts)

CO2 buy or not to buy?kyle_4375

I currently have a frame pump and have grown tired of having to keep it in place with velcro straps, etc. I'd like to get rid of it altogether. I've never used a CO2 pump. What are the pros/cons? Threaded/Unthreaded? Which one should I buy?

Thanks for your help

Buy one. Genuine Innovations makes many different varieties.

If you use the threaded, all you need it the inflation head. Threaded refills are more expensive. Unthreaded refills are cheap, but you need a housing to keep it from becoming a projectile when you puncture it.

I use an innovations second wind--hand pump to low pressure, and use co2 to fully inflate. no problems.

only concern is running out of co2 cartridges. for long/unsupported rides, i'll carry the inflator and cartridges for a quick fix, and a frame pump in case i run out.

to be safe rather than sorry, carry a frame pump and spend a few minutes longer changing a tube. FWIW.

I have never flatted more than twice in a ride, and that was a fluke (metal strips at a construction site sliced both tires). In 3000miles of riding I puncture about once every 800 miles and only once a ride, so 3 threaded CO2's and a threaded head are all I need. I could take only 2 and be fine, but 3 is just in case.

This weekend I helped a lady with her flat. She had an inflator, but for some reason it didn't work. I took out my pump and she was on her way in a couple of minutes.

I know some riders swear by them. Since I don't race, I have no problems with using and carrying a frame pump.
Definitely buy!BergMann

Frame pumps (& mini pumps in particular) are a waste of time!
The new version of the Innovations superflate accepts both threaded and unthreaded carts, so the debate ends there.
If you're just using this for road tires, stick to the cheap 12g threadless carts you can get at any sporting (i.e. hunting) shop.

As for needing a frame pump for longer rides, perhaps if you're doing the Race Across America, and don't have a support car. Personally, I have never needed more than 2 carts per ride on or off the road, even in 6+ hour events. CO2 will "bleed" through the pores in your tubes faster than air, but I've never noticed a pressure drop while riding.

Bottom line: no drawbacks to C02 other than cost of carts, which isn't major as long as you buy bulk and don't buy them from bike shops.

I use a Blackburn mini to seat the tire on the rim and then CO2 to fill. Carry one CO2 cartridge in the body of the inflator an a second loose one as a spare. Still have the mini pump if necessary.

When out on a group ride, I think it's rude to keep your friends waiting while one fusses with pumping up a tire. Just shoot with the CO2 and get back on the road.

Just my $0.02

Good luck.

CO2, threaded, all you need is the tiny little pump head. That's all I've used for 7 years now. I don't do solo unsupported centuries in the middle of nowhere. I also carry a shrader/presta adaptor just in case.
Definately buy! From a recent convert. I used to doubt, but...Ken of Fresno

now I'm a true believer. Get one that does both threaded/unthreaded. Walmart has the unthreaded CO2 for about 45 cents each in the 25 pack. Since I don't flat as often now that I switched to Axial Carbons, it's not an issue money wise.

I use to carry a CO2 system and 3 cartridges for 2 years. There was always the possibility (never happened) of getting more flats than I had cartridges for. I ride in remote areas so I need to be able to get home without depending on help. I bought a Blackburn Mountain Air and can get 90psi in a minute. The pump weighs 152g/5.3oz which is lighter than a CO2 system and 3 carts. Now it doesn't matter how many flats I get, with a bunch of patches and 2 tubes I don't have to worry about getting stranded.
