Getting a flat is a drag, but it's infinitely worse when you're dealing with a sub par mini pump. And while the Lezyne HP Drive Pump won't get air into your tire as fast as a floor pump, its durable aluminum construction and high pressure hose ensure that you won't lose any of your precious strokes to a leaky line or poorly sealed pump head. The HP Drive pump is built from an aluminum main shaft, with composite handle and end caps. But, don't be fooled by its compact appearance, this thing packs a wallop that makes other mini pumps green with envy. The hidden high pressure hose un threads from its storage place in the pump body, only to attach to the other end. Like Lezyne's full size pumps, the threaded pump head works with both Presta and Schrader valves. All you have to do is un thread the head, and flip it to change valve types. In our experience, this yields a solid connection that remains airtight, even as the pressure approaches the triple digits. Granted, as with any mini pump, you won't set any records for inflation time. But, for a high pressure mini pump, the HP Drive inflates tires quickly, and provides a comfortable grip the entire time. And the best part is that it's lightweight and compact enough that you may even forget that you have it with you. The Lezyne HP Drive Pump is available in the sizes Small and Medium and in the colors Blackhi gloss and Silverhi gloss.
