-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.
Bottom Line:
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.
