Blackburn 's AIRSTIK 2STAGE is the mini-pump that's just as good for big tires as it is for thin ones. Made from aluminum, its lightness makes you forget you're carrying it on your bike, so you don't have to worry about tire pressure.
With the push of a button, you can switch from inflating your mountain bike to inflating your road bike in an instant. With enough air for your mountain bike tires and enough pressure for your road bike tubes, the AIRSTIK 2STAGE quickly saves you from having several different pumps. This mini pump is also super-light and compact. It features a large-volume aluminum tube, so you can pump out more air with each stroke. And because even the best pump won't do you any good if it's sitting in the garage, Blackburn has also designed a bracket that attaches to the underside of the bottle cage , so you can take this pump with you on every ride.
No more cluttering up your drawers, just a small, super-light, dual-purpose pump that's perfect for all your different tires.
