CO2 cartridges: is 12g sufficient for small-wheels?

I have a CO2 inflator that I've only used a couple of times (with 16g cartridges). I'm thinking of buying some 12g refills which seem like they would work well with our small wheels. I'd like to hear from anyone who uses the 12g cartridges.

I have 20" Duranos on my TSR. Does anyone know if 12g would inflate one of those to at least 90 PSI?

Probably not but I don't know for sure. On my bike I need to manually pump + one cartridge of 16g.

BTW, if your motivation is price, check amazon. For example you can get 16g threaded cartridges for about $1/cartridge http://amzn.com/B0015V45F4

Thanks. My motivation is size, not cost. I'm constantly trying to minimize the essentials. Last year I replaced my wallet with a rubber band.

LOL. It IS a broccoli rubber band! But I don't roll up my cash like a mobster (or even have enough cash to make an impressive showing after buying the Moulton).

On my TSR I fit everything within a frame triangle bag. It contains 3 threaded 16g, CO2 valve, micro pump, 15mm wrench, patch kit, spare tube, road tool kit, Z Allen for the king bolt, etc.

Thank you, badrad. That's exactly what I wanted to confirm.
