High-volume pumps move more air per stroke, which matters when you're standing trailside with a 2.4" tire that needs to go from flat to rideable. The Pocket Drive HV from Lezyne applies this high-volume approach to a pump that measures just 145mm long and weighs 93 grams. The "HV" designation means the pump is optimized for larger tire volumes found on mountain and gravel bikes rather than the high-pressure requirements of narrow road tires. You'll reach rideable pressure in fewer strokes compared to a standard mini pump, which saves effort when you're already dealing with the frustration of a trailside flat.

The entire pump body is CNC-machined aluminum rather than injection-molded plastic. This construction method costs more but delivers a pump that resists the flex and wear that plague cheaper alternatives. The barrel surface is knurled for grip, so wet or muddy hands won't slip during pumping. The overlapping handle design is a Lezyne signature that increases the internal air volume while keeping the overall length compact enough to fit in a jersey pocket, frame bag, or the storage compartments built into many modern mountain bike frames.

Valve compatibility covers both Presta and Schrader through the integrated ABS Flex Hose. The flexible hose design reduces stress on valve stems during pumping, which is particularly important with tubeless setups where the valve is threaded directly into the rim. Yanking a standard pump head off a tubeless valve can unseat the bead or damage the valve seal. The flex hose maintains the connection while allowing natural movement as you pump.... Read More
