Designed specifically for gravel bikes and other mid-volume tires, the Lezyne Gravel Digital Drive Pro Floor Pump is the ultimate floor pump for quickly and accurately inflating tires measuring 32c and larger. Built around a larger-diameter barrel than the CNC and Classic Floor Drive pumps, the Gravel Digital Drive Pro pushes more air per stroke for faster fill-ups while still offering easy pumping action. The easy-to-read—and extremely accurate— 3.5" (88.9 MM) digital gauge ensures dialing in the perfect pressure is a hassle-free affair, offering /- .5 PSI (.3 BAR) accuracy up to 100 PSI (6.9 BAR) Equipped with a Tubeless Chuck, the Gravel Digital Drive Pro is equally at home with pre-ride top-offs as seating tubeless tires. Featuring a flippable design, the Tubeless Chuck easily threads directly onto Presta valves, or, directly onto the valve shaft once the valve core is removed in order to provide greater airflow for seating tubeless tires. The chuck also features a built-in valve core tool for easy valve tightening and removal. A versatile, extra-long hose allows for easy inflation whether your bike is on the ground, in the workstand or hanging out on your hitch rack at the trailhead. Built to last, the Grave Digital Drive's barrel, piston and base are meticulously machined from premium aluminum and complemented by a comfortable, stylish wood handle. The Gravel Digital Drive Pro is crafted in-house, 100% quality-controlled and fully rebuildable.
