FULL-SIZE POWER AT HALF THE HEIGHT: At 16.3 inches this compact bicycle pump is roughly half the height of a shop floor pump, yet it still reaches 160 PSI. It lives in a car trunk, a closet or a gear shelf instead of leaning against the garage wall. OVERSIZED 1.5 INCH BARREL: The wide air chamber moves about 40 percent more air per stroke than a standard narrow barrel, so a 700x25c road tire hits riding pressure in far fewer strokes. Fewer strokes, less sweat, quicker out the door. READS ACCURATE WITHIN 3 PSI: The 160 PSI analog gauge runs on a copper-core movement rather than plastic, so the number on the dial is the pressure in your tire. Dial in 35 PSI for gravel or 100 for road without guessing or double-checking. NO ADAPTERS AND NO SWAPPING: A dual-sided head gives Presta and Schrader each a dedicated port. Flip the lever, push on, lock it down. It seals without bleeding air off the valve, so your road bike, the kids bike and the stroller all share one pump. ACCESSORIES STAY WITH THE PUMP: A ball needle, two inflator cones and a brass valve adapter clip into a sealed case on the barrel, so nothing disappears into a drawer. The wide footpad base stays planted underfoot stroke after stroke.
