The Core 2 Floor Pump is built for folks operating on a tighter budget, but doesn&';t sacrifice any of the functionality of the Core 3 or Core Pro models. The AirTap head works with any valve you can find and the 2.5-inch-tall aviation gauge is easy to read and built into the base of the pump to give it a rock-solid base. DETAILS INEXPENSIVE DOESN&';T MEAN CHEAP. 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 3 during use. Whether you are in the basement, the garage or at the trail head, the Core 2 has you covered. SPECS:- Country of Origin Taiwan Product Weight 1242 grams
