The Lezyne Classic Drive HP mini pump is designed for high-pressure, low-volume applications. Oversize piston and aluminum shaft inflates tires to riding pressure quickly. Inflates quickly with 30% fewer strokes than conventional pumps. Lathe-turned aluminum barrel features a nonslip, textured grip. Overlapping nylon handle increases the stroke while decreasing overall pump size. Works with Presta and Schrader valves. Bracket mounts to water bottle cage bolts; rip-and-stick strap fully secures pump to bracket.
