2Stage Pumps
Blackburn’s 2Stage pump technology allows you to toggle between high-volume and high-pressure modes with a flip of the switch in the handle for faster inflation and less pumping effort. Two stage internals offer a high volume mode for fast inflation, and a high pressure mode to reduce effort at higher pressures.
