The Core 2 pump still shares all the techy bits of its big siblings, but is built for folks operating on a smaller budget. The AirTap head will function with Schrader/Presta/Dunlap valves and has an integrated bleed valve for dialing in your pressure. Our aviation-style gauge is 2.5 inches wide, and easy to read. It’s also built into the base to add to the stability of the Core 2 during use. Whether you are in the basement, the garage or at the trail head, the Core 2 has you covered.
