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 tyres. 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 tyres. Comfortable, Stylish and Reliable Track Pump This track pump's barrel, piston and base are meticulously machined from premium aluminium 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.
