I don't carry a pump to add air after using a cartridge. sorry for any misunderstanding. I carry 20 gram cartridges cuz I've been riding 700x45mm tires & now 29x2.25" tires. it's not uncommon for me to air down for a soft section then air back up when getting onto firmer dirt. & last bike's rear wheel/tire/tube had a tendency to pinch & leak, so I would sometimes after airing down, then have to continually add CO2 until the end of the ride. that situation should be gone now that I'm on bigger tires. admittedly, I waste some of the cartridge cuz I don't use it all, then leaving it on the inflator it either leaks out or when I get home & take it off the inflator, the CO2 escapes :/
