I guess what I don't understand is the need to get to 120 psi. In most cases, isn't 80 psi good enough to get home or back to your car? In other words, isn't the 12 g cartridges sufficient?
Yes...12g is plenty. Most people ride with their tires at too high of a pressure anyway (past the sweet spot between rolling resistance and comfort). A 12g usually gets me to around 90 psi which is plent for me to ride on.
