Blackburn’s Mammoth 2stage Anyvalve Mini-pump proves that big things come in small packages. 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.
