I've was going through my saddle bag and got looking at my CO2 cartridges, thinking do I need to carry 12 gram or 16 gram cartridges. How much pressure will I actually get out of one of these into my Conti GP4000 23C tires? What about into the 28C's on my comuter?
The only chart I've found that gives pressure doesn't give tire size.
If I got a flat on a century ride, I'd rather my tires ended up with more than 80 or 90 psi.
Has anyone actually tested the amount of pressure you get out of a CO2 Cartridge
