Lezyne's Gauge Drive is the premier choice for those looking for the perfect blend of performance and longevity in a hand pump. The Gauge Drive HP's (high pressure) optimized design allows you pump up your high pressure, lower volume tires such as those for road bikes, to the proper riding pressure with fewer strokes than similar mini pumps. Lezyne achieves this by using an overlapping handle and barrel with an oversized piston and shaft, while maintaining a slim package for easy stowage on the bike, in your pack or in a jersey pocket.
Simply remove the ABS hose from the inside of the pump, attach the hose to the opposite side of the pump, screw the hose into your valve and you are ready to pump. Other pumps use a rigid attachment to the valve, which may deform the fragile valve head and ruin tubes. Lezyne's ABS Flex Hose allows the pump to move independently of the wheel, protecting the valve head with a more secure connection which prevents accidental detachment, and allowing more ergonomic pumping and less rider fatigue.
Where the Gauge Drive HP really stands alone from other hand pumps on the market, is in Lezyne's ABS Pen Gauge, a precise and compact in-line pressure gauge that built into the pumps compact design, resulting in accurate air pressures out on the trail, as oppose to playing the guessing game. The ABS (Air Bleed System) features a button which releases excess air out of the hose for easy removal after pumping. The Gauge Drive really is an ingenious design.
The pump's body is a work of art in itself. The handle, barrel and shaft are completely formed of sumptuous CNC'd Aluminum, while the end caps are constructed of Lezyne's proprietary Composite Matrix material to maximize durability and rigidity. The solid, industrial design will perform in the worst of conditions, holding up to intense abuse and years of use. The Gauge Drive HP comes equipped with Lezyne's famous ABS Flex Hose and also includes frame mounting hardware for mounting to water bottle bosses.

Integrated Gauge for accurate inflation; contains clear and easy to read marks for both PSI and BAR
Patented ABS butt on releases air pressure in the pump hose, making it easy to remove the Flex Hose, eliminating the chance of unthreading Presta valve cores
First flat with my new pump was a terrible experience. In theory, this is a fantastic pump but in my experience: the connection from the pump (plastic grooves) to the top of the "pen gauge" (metal grooves) isn't sound. The connection from the pen gauge to the pump couldn't happen because the plastic threads on the pump itself are terrible quality and probably wouldn't hold up after multiple uses anyway. The connection to the pump should offer metal groves (on both sides) so it's a more solid connection to the metal grooves of the pen gauge. Instead of a good connection, I had to try to force air from the pump to the pen gauge while holding both in my hands. It took me forever just to get to 80psi on my 100psi tires. Additionally, the pressure indicators on the pen gauge wore off in my attempts to force air from the pump to the pen gauge. The numbers wore off during one use so if you buy one of these don't touch the numbers. You're better off spending your money elsewhere to ensure you get a pump that works.
I really need the guage to see if I am getting close to the correct PSI. Let's face it, in an emergency its essential to have one. You might as well have one that tells you if you are close to the correct tire pressure. I was able to pump up my bike to 80PSI and have not attempted higher. It's a light setup and will probably last me many years.
