Lezyne make numerous floor pumps, but they break down into 3 series:
“Floor Drive” pumps (6 models) are high pressure (160psi) and therefore low volume.
“Travel Floor Drive” pumps (2 models) are compact pumps meant to fit better in luggage for riders that travel.
“Dirt Drive” pumps (3 models) are a high volume/low pressure pump intended for mountain bikes. The gauge only goes to 70psi, and the pump barrel is noticeably larger in diameter than the floor drive models. Therefore they move a larger volume of air on each stroke, and would be more likely to seat tubeless tires.
I’ve run Stan’s tubeless for years, but I have a big air compressor…
