If someone told you "Build a pump that's light enough to ride with, durable enough to use every day, compatible with Presta and Schrader valves, outfitted with an integrated pressure gauge and bleed valve, complete with an extendable hose, and capable of putting down 50 PSI," you'd probably be like "Nah." That's what makes you and Lezyne different, though, because the Gauge Drive HV can do all that. Its high-volume design is perfect for pumping up MTB tires when you're on the go, and the CNC-machined aluminum and composite body is nice to look at and makes it pleasure to use. The extendable hose means no awkward twisting and bending, and the bleed valve lets you pop off a few PSI without any guesswork.
