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) gauge, which provides detailed measurement up to 100 PSI (6.9 BAR). And its classic wood handle is stylish and very comfortable to use.

The Sport Gravel Floor Drive is built in-house, 100% quality controlled and fully rebuildable for long lasting operation.
