<!--ProdInc[300298075]/Mall:[backcountry_US]-->We find ourselves in an internal debate between the Blackburn AirStik 2Stage and the AirStik SL ? faster pumping or smaller size. If you need it on your bike for a race, do you want to save 26g or have almost twice the air volume per stroke? We go back and forth, but the greater air volume does seem worth the trade-off. The AirStik 2Stage can deliver 3.5 cubic inches of air per stroke, which exceeds most other pumps that offer two different volumes per stroke. If you''re not familiar with these, you should be. There is a switch on the pump, in this case on the bottom of the handle, which allows you to choose ''high volume'' or ''high pressure.'' The latter is a polite way to say ''low volume'' ? something you will want as the pressure in the tire gets to a certain point as it makes the pumping easier. <h3>Details</h3> A mini pump for high pressure and volume tires Rebuildable design for a lifetime of use Small chamber achieves up to 160-psi Moves more air per pump than comparable pumps Frame-mountable for easy carrying Item #BLB004S <h3>Tech Specs</h3> Material : aluminum Valve Type : presta only Max Pressure : 160 psi Claimed Weight : 3oz (85g) Manufacturer Warranty : lifetime
