Blackburn Mammoth 2 Stage Anyvalve Mini-Pump Black

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 a lifetime.
