The Blackburn Air Stik Long Neck pump has a unique detachable head with a thumb lock. Any rider who has accidentally torn a value stem in the inflation process will appreciate this revolutionary feature. The Air Stik Long neck has high and low pressure mode activated by a switch on the end of the pump and is capable of reaching pressures up to 160 psi. The high and low pressure modes allow faster inflation with less effort. The Air Stik Long Neck works for both Presta and Schrader valves and comes with a cage-style mount.
the unit hooks up to the tire very nicely. in a trial i attempted to pump up a GP4000 25c tire. i first gave 50 strokes in the low pressure setting. it became very hard to operate the pump by that time. i switched to the high pressure setting and gave it 200 strokes. i then measured the pressure: 48 lbs. i think this pump, like every other similar sized pump i have owned or tried, is useless. well, i guess 600-700 strokes might do some good, but i lost interest,
