Blackburn: The Airstik 2Stage is a durable aluminium pump with enough puff for mountain bike tires and enough pressure for road tubes, too, thanks to the two-stage high-pressure/high-volume switch. Presta only, though -- what are we, eight years old and riding Huffys? Whether you ride on road, off-road, or somewhere in between, the Airstik switches easily between high volume and high pressure to suit your pumping needs. Who is this Schrader anyway? Fewer and fewer folks are running Schrader valves, so weve made this pump with a push-on, Presta-only head for easy use. Constructed from aluminium, a lightweight and tough material for extra durability and a timeless look. And even the best pump wont do you much good if youve left it in your sock drawer. This pump comes with a discreet frame mount that attaches under your water bottle cage.• 2-stage high-volume/high-pressure switch• Push-on Presta only head • Frame mount attaches under water bottle cage• Up to 160 PSI
