Blackburn Mammoth 2Stage Anyvalve Bike Mini-Pump

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.
ANYVALVE PUMP HEAD – Works great on presta, schrader, and dunlop valves. No leaking, no fuss, clean and simple
HIGH VOLUME – This mini-pump is specifically designed to push more air per stroke, saving energy that you might need for riding
2-STAGE TECH – Goes both ways! Whether you ride on-road, off-road, or somewhere in between, the mammoth anyvalve switches easily between high volume and high pressure to suit your pumping needs
