The Mammoth get to 40 to 50 psi very quickly at the LP setting and I can get up to 70-80 psi with some effort on the HP setting. The two Airstik pumps’ LP setting are about equal to the Mammoth HP setting in volume and effort. Because I am changing air pressure if not my tires pretty often on my recent tours, these two stage pumps have work well for me. Often I take two pumps giving me in effect a three stage pump.
