The Gravel Digital Drive Pro is the ultimate bike floor pump with a medium sized barrel designed specifically for gravel bikes and other mid-volume tires. The chuck is tubeless specific and “flips” for Presta, or a threaded Presta shaft (with the valve core removed) to provide more airflow for seating tubeless tires. Its barrel, piston and base are meticulously machined from premium aluminum and complemented by a comfortable, stylish wood handle. Pumping is versatile and more efficient thanks to an extra long hose and a larger 3.5” (88.9 MM) digital gauge, which provides precise measurement up to 100 PSI (6.9 BAR). The Gravel Digital Floor Drive Pro is built in-house, 100% quality controlled and fully rebuildable for long lasting operation.
