If I'm going to put a pump back on my bike, it's going to be a full size frame pump.
My seat pack now has; 2 tubes, 3 16g cylinders(100-130psi), a small inflator head and a patch kit.

The idea about maybe pumping in a bunch of air and then CO2 is a good idea, that way I can purchase the cheaper 12g cylinders that give you about 90-100 psi.

When are they coming out with a CO2 cylinder that has sealer in it? Or...tubeless wheels.
