Blackburn Mammoth 2 Stage Any valve Pump Black

It's the tiny, big-volume pump for big-volume tires.

DETAILS 

BIG AIR. EASILY! 

While the big diameter barrel was designed to pump more air per stroke into a high volume MTB tire, its 120 psi max pressure makes it road-worthy as well. Simply flip the switch between High Pressure for road and High Volume for mountain for easy inflating. With high-end alloy touches, this pump is built to last you a lifetime.
