Ok, I'm tired of taking forever to air up. I'm going to build my own CO2 system to air up after my rides. I have read the many pro/con posts and watched numerous videos, I want to use the CO2 system rather than a Viair or other OBA system. So, anyone have a 10lb cylinder they want to part with? I can get them locally, but thought I'd help alleviate space from a fellow XNer first if the opportunity is there.
