Compact hand pumps are a must-have item on the road; ride more than a few miles from home and you’re bound to get a flat. The $50 Lezyne Gauge Drive HP is an aluminum bodied pump meant for high pressure, low volume tires and equipped with an in-line pressure gauge meant as a step up from cheap feeling plastic bodied mini pumps. If nothing else the shiny aluminum feels good in your hand, even if I’ve never been one to tear through plastic pumps. At 230 mm long the Gauge Drive HP fits in a jersey pocket and larger seatbags, or use the provided bottle cage mount. The handle side hides a the hose and in-line gauge inflator which has a reversible Presta or Schrader chuck with a bleed valve. Screw the hose into the end of the pump body, careful to not cross-thread the plastic fitting, and go. Over the past season the Lezyne Gauge Drive HP has bailed out a few flat tires and aired up the travel bike outside the airport. The ABS Pen Gauge gives a reasonable ballpark pressure reading on the side of the road, but you’ll be hard pressed to tell a 10 psi difference with it. Be mindful of not unscrewing the gauge itself as I once did and avoid a momentary heartrate spike (I was able to put the gauge back together on the spot). The screw-on Presta chuck and small section of hose go a long way to help prevent broken valve stems out on the road, which happens to be the most common and least convenient place to break them. Like any small pump it’s going to take some effort to get to riding pressure with a road tire, but it will keep you rolling and is able to get to 100+ psi without spending all day.
