In our 35+ years of tandeming we have found the Topeak Mt. Morph and Road Morph to be the best so far.
The Mt. Morph is a bit lighter/shorter than the Road Morph version. They are by no means a 'minimalist' pump, but they certainly are up to the task. Max pressure claimed: 160 psi.
On my single bike I carry a Quicker mini/pocket pump, claims to be able to reach 154 psi, but it takes a lot more pump strokes than the Topeak.
With Topeak we can get 100 lbs of air with 100 easy pump strokes in a 700x25 tire. The Topeak is actually a floor pump in disguise!
*Almost* a pleasure to get a flat . . .
Just our experience.
Pedal on TWOgether!
