Lezyne Pocket Drive Pro HV Description: The Lezyne Pocket Drive Pro HV is an amazingly compact and lightweight bike hand pump that's small but still manages to dish out plenty of pumping efficiency for high-volume tires, such as those found on gravel and mountain bikes. The knurled barrel, handle, and oversized piston are all constructed from durable CNC-machined aluminum, and the overlapping handle design increases the available air volume while keeping the overall length short so this pump will easily fit in jersey pockets, inside of frame bags, and potentially within the storage compartments found in modern mountain bicycles. The integrated ABS Flex Hose has a reversible air chuck that is compatible with Presta and Schrader Valves, and includes an integrated valve core tool. Add in the ability to completely rebuild this pump should something wear down or go missing, and you have a highly portable pump that has performance that rivals that of larger pumps and that will provide years of worry-free service.
