Lezyne Gravel Digital Drive Floor Pump Matte Black. The Sport 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. Pumping is versatile and more efficient thanks to an extra long hose and a larger 3.5” Digital (88.9 MM) gauge which provides detailed measurement up to 100 PSI (6.9 BAR).

Tubeless specific chuck “flips” for Presta or a threaded Presta shaft (with the valve core removed) to provide more airflow for seating tubeless tires
