Drop enough in elevation and so will barometric pressure, leaving your once springy shock feeling like a ride in grandma's 1987 Oldsmobile. Fortunately, Lezyne came up with a gauged mini-pump that will blow other shock pumps away-literally. The Shock Drive pump's 100% CNC machined aluminum housing makes it light and bomber, and when mushy shocks rear their ugly heads, happiness overtakes you as you pull your disaster aversion tool from your pack.
