William Johnson Jrwrote a review of Blackburn Airstik 2 Stage Pump on October 23, 2014
Familiarity: I've used it several times
Easily fits in my jersey pocket, on my bike frames, or in my hydration pack. Works great on fat bike tires and road tires. This is a necessity for fat bikers in my opinion...conditions on the trail/road can change quickly.
