An aluminum air chamber with inflator head that stores an air charge of one liter, up to 200 psi / 14 bar. Works with a floor pump to quickly fill your tires and ensures proper installation on a tubeless rim at home. Once you flip the selector from “CHARGE” to “INFLATE” mode, air bypasses the chamber as you use the floor pump to inflate your tire to the perfect pressure. An integrated flexible hose with pump head works with Presta and Schrader valves and takes stress off the valve stem while pumping.
