A high volume floor pump optimized for use with mountain bike tires. Made with a CNC machined aluminum barrel and base, a steel piston and an oversized varnished wood handle. The barrel, piston, hose and connectors are oversized to deliver twice the air flow per stroke to quickly fill tires or seat tubeless tire systems. The ABS Flip Thread Chuck and long rubber hose easily reach both Presta and Schrader valves on a stand. The Speed Chuck is included for fast press on valve engagement. The 2.5 oversized gauge is very precise and easy to read. An anodized high polish finish makes this pump stylish and durable.
