Now, anyone who changes tubes, patches, or uses cartridges definitely needs to police the area.
I have the Mini Dual G on the hybrid. It's rated at 120 psi, but it's a real bear just getting in the 65 psi needed for the tire. Wears you out after 45 psi and I can't imagine trying to use it for up to 120 psi. You would have no arms left. Although it works a bit better than the old Giant pump I had, it isn't anything to write home about. I wanted a small (mini) pump rather than a full length frame pump. I guess I learned my lesson and should have got the full length frame pump instead.
The main reason I don't use a pump on my road bike is because I have a hard enough time with those stupid presta valves when using my floor pump. I have no intention of trying to hold a hand pump on those things and try to inflate a tube at the same time.
