The Lezyne Road Drive is a high pressure hand pump made entirely of aluminum for precise and lightweight construction. The barrel, handle, piston, end caps and pump mount are all custom CNC machined. The HP design makes this a frame pump replacement, easily inflating tires to riding pressure with fewer strokes. It comes equipped with our ABS Speed Flex Hose, which is a Presta ONLY inflation system. One end of the hose is a threaded Presta valve connection with ABS, while the other side has Lezyne's Slip Fit system for fast valve engagement.
