The Serfas Air Force Tier 2 is the most reliable floor pump they have ever sold. All metal construction, no plastic is used in the barrel or the base. This pump will last. Equipped with a base mounted dial pressure gauge, with a maximum 160 PSI capability for inflating even the highest pressure road bike tires. The best feature is Serfas' Smart Valve pump head that inflates both Presta and Schrader without using a valve adapter or switching around internal parts. The pump head adapts itself to the valve type, just press it on firmly and flip the thumb lever up.
