The Lezyne Tech Drive HV Pump is a life saver when goat heads attack. Offering lightweight design, and inflation efficiency that rivals most floor pumps, the Tech Drive HV is a trail ready hand pump that you'd be happy to use at home. The Lezyne Tech Drive HV Pump features a CNC machined aluminum handle, barrel, and shaft. The use of rigid, precise materials allows the Tech Drive HV to inflate tires to riding pressure with 30% less strokes than conventional hand pumps. The over sized piston and handle are integrated into the body of the pump, and form a sleek unassuming design. The Tech Drive HV Pump comes outfitted with the Lezyne ABS Flex Hose. This feature is a huge ergonomic advantage for roadside inflation. With the ABS Flex Hose, you don't have to strain away at precise valve angles. Simply fit the Slip Fit System valve head to the stem, and pump away at an angle of your choosing. The Flex Hose is also equipped with the Air Bleed System for even greater accuracy in pressure regulation. For a low profile, the Carbon Drive 2 utilizes a compact design that stows the hose inside the pump handle when you're not using it. The Lezyne Tech Drive HV Pump is available in sizes Small 170mm, 111g and Medium 216mm, 127g, and includes a Composite Matrix mounting bracket. The Tech Drive HV has a maximum of 90psi, and is compatible with Presta and Schrader Valve fittings, via its reversible hose.
