Bell's Zephyr Series floor pumps are specifically designed to inflate tires fast. Their tall barrel design offers less resistance, making it easy to inflate the thinner, high-pressure tires found on road and commuter bikes. The Zephyr 350 features a reversible pump head for both Presta and Schrader valves and rugged, steel barrel construction for years of reliable performance. A ball needle and inflation cone also are included for sports gear and inflatable toys. They store conveniently via an integrated hose clip. The Zephyr 350 inflates tires up to 100 PSI.
