The Gravel Digital Drive is a high-quality 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 and piston are built from high-grade, durable steel and mounted to a rugged Composite Matrix base. 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). And its classic wood handle is stylish and very comfortable to use. The Gravel Digital Floor Drive is built in-house, 100% quality controlled and fully rebuildable for long-lasting operation. - CNC-machined aluminum construction - Precision 3.5-inch digital gauge (100 psi / 6.89 bar) - Extra-long nylon-reinforced braided hose with aluminum couplers - Varnished wood handle - ABS1 Pro with Presta / valve stem chuck
