Ride more, stroke less.
The Lezyne Pressure Drive Pump has all the functionality of Lezyne's Carbon Pressure Drive, just fabricated out of CNC-machined aluminum. You get a nice price break for a minimal weight penalty. The Small pump is 170mm long, while the Medium is 216mm long.
Pressure Drive pumps are High Pressure units, HP for short, designed to pump up road tires. What separates Pressure Drive pumps from Road Drive pumps are the barrel diameters. 20mm vs. 17mm. You can push more air with a larger diameter barrel and thus pump a tire up faster, but it will take more arm strength to do so.
One of the great features of Lezyne mini-pumps is that they all come with flexible thread-on hoses rather than a fixed pump head. This is a huge benefit for a few reasons. One is security: thread it on to a Presta or Schrader valve and it won't come off. Another is ergonomics; you aren't limited by holding the pump at a perfect right angle to the valve. A third is that this Flex Hose is ABS-equipped -- it has a bleeder valve on it.
The Lezyne Pressure Drive Pump comes in two lengths: Small and Medium. Maximum pressure that one can attain with this pump is 120psi. There's even an accessory Pen gauge hose that screws into Medium pumps. The pump comes in High-Polish Black.
- ABS (Air Bleed Equipped) for dialing in exact pressure
- High Pressure design allows pump to reach riding pressure with 30% fewer strokes
- Frame mount included

Works pretty good, watch your valve core
- Familiarity: I've used it several times
I've used this for mountain and dirt road (CX bike) and carry it on the road. The durability is very good, the hideable hose is nice and convenient and makes pumping vigorously less un-nevring as you are less concerned of ripping the valve stem out of the tube. I have the "medium" size one and its slightly longer then your average jersey pocket length. If I pack my pockets with food and stuff, I don't have to worry about having the thing fall out. For mountain and cross the volume is sufficient. I have not had any flats on the road, so I can't speak of how it does at road pressures.
Now the downside. The hose screws onto the valve stem, making a nice and tight seal. You pump it up and life is good. However, the seal is almost too good and grips the valve core. When you screw the hose off, if the valve core is not extremely tight, you take the core with it, having all your hard work air fly out followed by a long list of course words. I'm giving this 4 stars as it works fine IF you use a small valve core wench (sold with some brands of stems) and stench the thing down.
Small, Light, Elegant Design ...Works OK
This is replacing the venerable Topeak Road Morph G. In the process of getting the backpack off my back, the old Topeak was the last thing... and was just too big to have hanging off the beautiful frame of my bike.
Enter the Lezyne Pressure Drive. Small enough for a pocket or a more discreet frame mount, and lighter. The Pressure Drive pumps pretty easily up to about 80 psi, but my weak arms are tapped out before 100psi... but I've seen others do it, it's just not for me. But it does the job and gets me back on the road, and pretty darn effectively. I will make the sacrifice and take this over the larger Topeak anyday.
In the two times I've used it I've never broken a valve stem or unscrewed a valve core, as others have reported.
For the sake of clarification, the medium...
For the sake of clarification, the medium will fit presta and schrader valves, and comes with a gauge that screws in to the short side of the flex hose? If so i'm sold.
The Medium does NOT include the gauge, it is sold seperately.
Works great, it takes a decent amount of pumps to fill up a tube but sans a monster frame pump what doesn't? I like the mount which allows you to still use your waterbottles. The mount has a velcro wrap as well as a clip and it is very secure.
Very nice pump it is compact and works well I don't even mess around with co2 anymore. This is the perfect pump for my eastern Sierra rides where there is no cell phone service and u are on ur own. And now I never have to worry about running out of co2 ever again.
Does this pump attach to the side of a...
Does this pump attach to the side of a bottle cage allowing you to use 2 water bottles? Or does it take the place of 1 of the bottle cages allowing you to use only 1 water bottle?
It mounts to the side so you can use 2 water bottles.

Does the ABS thing mean you can use this as a shock pump?
ABS= (Air Bleed Equipped) for dialing in exact pressure.
It's for tube onely
