-A precision high-volume floor pump optimized for use with mountain bike tires -Made with a steel barrel and piston, aluminum base, and varnished wood handle with an oversized contoured grip for comfort -The barrel, piston, hose and connectors are oversized to deliver double the air flow per stroke to quickly fill tires and seat tire beads on tubeless tire systems -Equipped with ABS (air bleed system) chuck to allow release of back pressure and eliminate the chance of unthreading Presta valve cores -Oversized 2.5" diameter gauge assembly, 70psi max
Strengths: high volume, smooth action, stable base, long hose, comfortable wood handle
Weaknesses: That god awful screw on pump head.
This is the best and worst pump I've ever used. So many good things about the way it works and it's good looking. But that pump head just sucks! I switched to the 'crack pipe' head that presses on and it's a little better. Eventually I'm going to retrofit a SKS pump head onto my dirt drive. I also wish the gage went to 110. Then I could use it to pump road tires as well. It takes a lot of effort to get the dirt drive to that pressure but it's fast. Having literally pumped 80 wheels in a morning that's important to me.
