Source for Co2 Cartridges?

post #1 of 15
Thread Starter 
The only time I have bought 16g Threaded Co2 cartridges at my local shop they have been part of a larger purchase, so I never really noticed the $3 price tag. After a relativity unlucky week (I will never ride a patched tube again...) I've had to use 3, and need to re-stock my bag plus the roommate needs a few for hers...

I looked into paintbal/BB gun supplies, but they are all unthreaded. There has to be a cheap source somewhere.

Oh, I found some on Amazon, $30 for 30, so if anyone wants a bunch I could buy this and distribute...

I think I might order 30 and try to sell some here:

if you refuse to patch, get used to paying an additional $3 for tube every time you flat,  on top of the 'cheap' $1 gas cartridge. I'll stick with patch kit and pump. Free air, imagine that!

I'll ride a patched tube home, but I don't think I'll ever ride it again after that. As frequently as i have had flats (until last week) it stays pretty cheap...

Do you use pre-glued patches?

Here's what happened to me. I put new tires and tubes on a couple weeks back and went out for a ride with no problem. A few days later I went out for a ride, went about 10 miles when we turned around to head back (paved canal path). About 5 miles from the car all of a sudden I felt something start to thump, and jumped of the bike. I looked quickly at the front tire, then noticed the back had popped of the rim 1/2 way. Before i could let the air out of the tire the pinched tube blew about 6" from my face, scared the shit out of me!

Anyways, I patched it with a pre-glued patch, aired up and rode back to the car with no issues. A few hours later at home I hung the bike on the rack and let some air out of the tires. Before my next ride, I aired up all the tires, paying attention to my rear to see if there were any issues. When I took the bike of the car at the trail, I checked the pressure again, it was fine. Less then a mile down the trail I felt it going flat again, the patch had peeled off. I didn't even bother with another one, I swapped in my spare tube.

Odds are it was the size of the explodd section that caused the issue, but considering the milage I have been getting out of tubes (2 isince last year, this one and the stock tube that split down the seam) $5 for a new one after a problem doesn't seem to bad.

 No to glue-less patches. I know one guy who uses them. Blow outs and split seams are not generally repairable. Puncture from thorn, glass, staple, small nail generally are.

Yeah, I should have known better. I patched it and rode home, and in the back of my mind was thinking that i should change the tube, as it was a nasty blow out...

That sounds pretty suspect. Not sure how confident I'd feel about that.

What could cause that?

 Damaged bead. It happens. You might see a mark where it popped off.

That would suck, these tires are about a month old..

I'll keep an eye on it, but I've had 2 rides since the incident. My only thought at the time was it could have rolled off while crossing a set of RR tracks or storm grates under a bridge.

Pre-glued patches stink.

I always carry ant extra tube or 2 with me. Take the punctured tubes home and patch. I usually put the patch on and clamp it down with a C-clamp. I then pressure check the patched tube. The patched tube then becomes my spare.

Sometimes if a tire isn't seated on the bead properly it will bow off under high pressure. I usually go around the bead and squeeze it against the rim before inflating.

Fixing a tire can be an art. Weber and I used to time each other. Fixing a tire quickly can save you a DNF in a race.

Some of the threaded CO2 pumps work with non-threaded cartridges also. I have one that works with both, also works with 12 and 16 gram cartridges and comes witha screw on pump assembly. I use the 12 g cartridges (much cheaper).

You can saw the ends off and make wind chimes for the sweetie afterward. : )

I use tubeless in my MTB's now.

What he said . I've got a rotating bevy of patched tubes, even though I have a dozen new tubes from bonktown somewhere in the closet. I think the puncture-resistant tube I just got from you, krp8128, will be my first patch-less tube in more than a year! Riding on NYC glass-strewn streets has made me a bit frugal with air and tubes. I have a friend, though, who buys CO2 cartridges in bulk, probably from Nashbar or some place like that (I'll ask him).

I just asked him, he says he gets them off eBay, and the expiration date is so negligible that you could buy in bulk and they would last you for years, should you use them that infrequently.

Along with Telerod, though, I like my free air. Better for the environment, good for my arm muscles. JZ brings up a really good point, though. I don't race, therefore I don't need cartridges. If you race, you might want to have a few handy!

Chainlove it right now for a Blackburn AirFix CO2 Inflator...uses threadless cartridges AND it's a multi-tool if you're interested.
