OK, it's time to ditch my oh-so-cute but useless little mini pump. It's a blackburn & I'm luck to get 80 pounds in. Is there a frame pump that can deliver 120 pounds? I have good upper body strength so it isn't a matter of not being able to push that sucker.

Anybody use CO2 cartridges? I saw somebody blow a tire off a rim one time, but maybe he screwed up (duh, ya think?) rather than the cartridge being too powerful.

I had a flat today & had to gingerly ride home after getting ~ 80 pounds in and worrying about pinch flats. I want to be able to keep riding. Whaaa!
