Also once you get home you should deflate your tire and re-inflate with normal air, C02 will leach out the tire faster than air so while it will be fine for the rest of your ride after a flat it may not make it through a ride on a subsequent day.
Two comments: 1- Pro bike has one of the best valve to inflate tires with CO2. You will not loose any CO2 2- allow some time after disconnecting the valve/ CO2 before closing the valve on the tube. Reason. There is a seal on the valve that was exposed to low temperature. By closing it while frozen it will have more chance to fail. By allowing some time you will let the ambient temperature to equalize at the seal level and therefore helping it to perform.
I get my adult son to check my tyre pressures for me prior to every journey as I have heart failure, hence I carry two cartridges with me just incase as there's no way I'd be able to pump my tyres up. BUT I've never had to use them yet, so this is a great video for explanation as well a hint for me to practice this now at home so many thanks.
Best Video on CO2 inflation , why ? this guy addresses the shutoff valve by , yes blowing on the empty ( sans co2 cartridge ) to convince yourself usually clockwise is CLOSED , profoundly important lest its open and you freeze a finger to absolute 0 F. # 2 ) the place to learn is not under duress while out on the road but at home to practice how this thing actually works - solid gold advice !
Thanks for this video. I just want to add that a friend of mine used a CO2 cartridge in cold weather and the tire valve froze and fractured off. So take care in cold weather because the CO2 cartridges do get very cold. And thanks for all the great videos.
Don't give up on your hand pump! Always pump at home, where you can gauge exactly how much pressure you have in your tire. On the road, the CO2 cartridge is a godsend, to be sure. But you won't know the exact pressure inside your tire. Use CO2 for the road repairs and use the trusty pump at home.
I recently filled a tyre with CO2 and it only stayed up for only 24 hours. With air from my foot pump inflates them forever. I read that CO2 is impermeable to inner tubes. Is this true?
The difference in permeability with CO2 is insignificant. The most likely culprit is a stress crack in your inner-tube at the valve stem junction. This or another intermittent leak is most likely the cause.
@@velotiqueBetterWatchSaul This isn't true. The coefficient of permeability of CO2 compared to air is very significant and can explain a major loss of volume in 24 hours when compared to air. Not a complete loss, as in this example, and yo'u're probably correct in stating that Jem Pro has another issue.
is it safe to use c02 even if there is compressed air in the tire? or when there is c02 in the tire and you top it off with compressed air is that ok or can the tire explode?
Hey, Dingledork, swing and a miss. My 7 yr old daughter repaired her own tire and inflated with CO2 and she didn't leak any, not a peep. It also might be a better idea to recommend recycling over disposal. Only we can make a difference. Or the canister could be designed to bio-degrade quickly with some positive effect but I can't hold you responsible for making that happen can I?
Also......be mindful......that you WILL need to "refuel" your tire pressure with a regular bike pump when you get home.....as I found out the next morning when my tire was almost flat.....I thought I had gotten another flat tire AFTER the initial flat tire but found out that the CO2 air will permeate through the tire unlike regular air that does not....great video!
can anyone explain to me why a carthridge is better than a mini pomp ? A carthridge is for one use..a pump is for many uses ..right ? So maybe i should keep my mini-pump !
Have you tried using a mini pump to inflate a road bike to 100+PSI. Lots of work compared to an instant 10 seconds for a CO2 cart.Try both and the decide what to use.
at least with the pump you Don't have the stress of the failed inflating attempt that you have with the CO2, I have a carthridge...and a pump. I have yet to use the carthridge. I probably will have to practice with it before a real puncture happens, cause to try that little thing when you are on the road fighting with a tire is not my cup of tea...
PierreC2: I carry two to three CO2 cartridges AND a bicycle pump (on the side of my water bottle cage). Occasionally I've used the pump just to make sure my clinchers are seated, then I'll finish it off with the CO2. As for why CO2, it's FAR faster and more likely to get closer to the correct tire pressure than a hand pump alone.
If I start with an empty 23x700c tube, I can barely get 90 psi out of a 16 gram cartridge at 20C air temperature. On a hot day the pressure may be significantly higher. Here is a hand chart www.genuineinnovations.com/blogs/learn-about-our-tech/how-much-co2-does-your-bicycle-tire-need.
Most of them will work with either type of valve. I like the Velochampion one which screws onto either type of valve which is more secure, and has a little lever to control the flow.
