The Arundel Floor Pump 1 is the world’s only pump with an anodized forged base. The forged design is extremely durable while the large 3" guage is easy to read and clutter free. The handle on the pump is composed of wood and is comfortable to the touch and resistant to temperature changes. The tube is composed of mandrel drawn aluminum that helps insure tight tolerances. The internal parts are made of stainless steel to help prevent rust. As all Arundel pumps are fully serviceable as the presta pump head features a thumb lock mechanism with a serviceable grommet for sustained use over time.
