I managed to post this note in the wrong thread the other day...no computer genius here!

I'm a recent convert to CO2 usage on the road. I have observed that my CO2-inflated tires do not hold pressure as long as pumped tires. I thought it was just me, that I'd done something wrong, but obviously others have observed the same thing.

I resisted using a CO2 inflator and always carried a Road Morph pump with me (which is a very nice pump, imo). Unfortunately, the RM does not fit on my new Ruby and I've been forced to carry a mini-pump (a Blackburn Airstik: http://www.dealhaven.com/storefrontp...id=9720&dfid=1 ). It works but it's a MUCH greater pain the in rear. So, I pulled the CO2 inflator out of moth balls and now carry it and a few cartridges on my bike as well as the mini pump for back-up. It's a compromise: neither one by themselves is an ideal solution.

And +1 that those empty CO2 canisters are recycleable. Any empties I might have after a ride are put right into our recycle bin for weekly pick up and we've had no complaints so far.
