Designed for Fat and Semi Fat tire bikes, the Air Tool Big Bore Pump packs massive volume-per-stroke, and it features a head that still works with winter gloves on to make it perfect for backcountry winter fat biking. Note: The pump head can be stiff to release. We found that holding the pump in your palm and popping the head off with your thumb is the most effective method of release.
