Pretty much what I find are pumps made for 622x23 low volume/high pressure tires and 26 x 2+ inch high volume/low pressure tires. To quote a poster on another thread, “The market has spoken.” It just hasn’t spoken to touring cyclists. What we are offered are pumps that take half a day and two aspirin to inflate the average touring tire or the arms of Hercules to get ten to twenty psi shy of your desired pressure.

For me the problem is compounded by the fact I can be on paved roads with 28/32 road slicks (100+ psi), but I have a set of 40mm wide dirt tires in the bottom of a pannier if the road/single track less traveled calls out to me(40 to 80 psi).

My answer is a two stage pump. There a several on the market speaking to me. The ones I have owned are all Blackburns: Mammoth 2 Stage, Airstik 2 Stage and the Airstik Longneck 2 Stage. It depends on what tires I bring as to the pump(s) that get attached to the bike. 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.
