I use a Lezyne Pressure Drive medium. It uses a hose to attach to the valve so you don't have to worry about snapping a valve off while pumping. It's small, lightweight and I can get 100psi out of it (tested on my road bike).


I run 26"x1.5" Schwalbe Marathon Racers at 80psi when commuting with no load and at 60psi when fully loaded.
