The Lezyne Alloy Floor Drive is a high pressure floor pump with a CNC machined aluminum barrel and base, a steel piston, and an aluminum and varnished wood handle. The ABS Flip-Thread Chuck and long rubber hose easily reach both Presta and Schrader valves on a stand. The included Speed Chuck makes this pump compatible with disc wheels. The 3.5" oversized gauge is precise and easy to read. An anodized high-polish finish makes this pump stylish and durable.
