Air Tool Big Bore Pump

Built for fat and semi-fat tire bikes, the Air Tool Big Bore Pump from Specialized packs massive volume-per-stroke to make easy work of inflating on the go, and also features a head that still works with winter gloves on so you don't have to worry about freezing your fingers off on the snow-packed trail. Its flexible hose attachment allows for aggressive pumping without fear of damaging your valve stems, and the coarse machined aluminum construction gives you a solid grip in cold, wintry conditions.
