No one likes getting a flat. With the Lezyne Alloy Drive Hand Pump, the hassle of fixing one on the road or trail just got easier. The Alloy Drive is a compact high volume hand pump made of custom CNC machined aluminum for precise and lightweight construction. The HP design easily inflates tires to riding pressure with fewer strokes. The overlapping handle and barrel, with oversized piston and shaft, are integrated into a compact design. It comes equipped with Lezyne's ABS Flex Hose, which has a threaded Presta connection with ABS on one side and a threaded Shrader connection on the other. Lezyne's Pressure Drive high pressure design let's you pump up to your desired pressure with 30% fewer strokes then comparable mini pumps.

Lezyne is unclear about their product lineup. My understanding:
Pressure Drive = High quality, decent volume, suitable for touring tires/general purpose
Road Drive = High quality, low volume, suitable for high pressure road tires
Alloy Drive = High quality, high volume, suitable for mountain bike tires
Tech Drive = Similar to pressure drive, but with some plastic parts in non-critical places
Sport Drive = Entry level pump that isn't durable
HP Drive and HV Drive = In-between Sport and Tech drive (high pressure or high volume variants)
Gauge Drive = medium size high quality pump with the ABS pen gauge included (you can buy the pen gauge separately)
Given all that, I picked the small-size Pressure Drive and am happy with it. Gives my arm a workout to be sure, but gets the job done. It would not be fun getting a tire much above 60psi using the Pressure Drive small, though.
I use the Pressure Drive small with the ABS pen gauge stored together in a plastic bag, and keep the small ABS hose in stowed in the handle as a backup in case the pen gauge breaks.
I have replaced this pump with one that has a flip lever, which IMO is a better design.
This pump has a nice mounting system that fits between the water bottle cage and the frame. The pump itself is held parallel to the frame tube at a slight offset. I find it does not interfere with my pedaling mounted on the seattube.
I have gotten a flat and had to use the pump since I purchased it. Putting 80 psi into a 25mm road tire with one of these things is not by any means easy, but the pump is sure smaller and lighter than a good floor pump. That's the tradeoff.
This pump is easily adequate for lower pressure CX or MTB tires. I would get a bigger pump if I wanted to run higher pressure tires (say, 19mm tires, or tubular, or if I were a heavier rider).
I used to make due with a far, far inferior emergency pump. It did "work," but just barely - I could inflate my patched up tubes enough to get back on the road, but it took forever and I could never get them to the recommended PSI.
After enough frustrating experiences with the old pump, I decided to see what the new state of the art was. I was excited to see Lezyne's offerings, since I'd recently been very impressed with their pedal wrench.
In use, the pump is highly effective. You don't need a ridiculous amount of strength to operate it. You *will* get a workout from all the reps you get pumping with this guy, but it's part of the tradeoff you have to make of max pressure versus max volume, and it's not that bad. I can reach the proper PSI on my road bike tires, something that wasn't even possible with my last pump.
The pump I purchased is the "small" version, because based on the measurements it seemed like it would fit my emergency saddle bag. It does. A hair under 7.5" long and with a diameter of just under 1", it's like a slightly supersized cigar. A mounting bracket is included (which can sit beside your water bottle holder) but you may not even need it. The device is small enough to fit in a jersey pocket.
How nice it is to handle something that's made out of metal. The pump feels like a quality product and it is.
Probably the most clever bit of design is the reversible presta/shraeder tube, which stows away inside the body of the pump when not in use. You screw it onto the pump when you want to use it, giving you a lot more breathing room than you get with most pumps that are rigid and just stick right onto the valve. With the flexible tube I can move the pump around to the optimal position for pumping while it's attached to the wheel.
I don't know how much it weighs, but the general answer is "not a whole lot." It's certainly lighter than my last pump.
Bottom line? It's a really great product, a really clever design, and a reasonable price. Get it.
Nothing is worse than pumping up a fresh tube and just when you think you are done, it pulls your valve stem core out and you have to start all over. I could be doing it wrong, it could just be an issue with the one I got, or it could be all the inner tubes I have came with loose valve stem cores. *Note: I am using the air purge valve before disconnecting; it doesn't make a difference. My solution is to pre-tighten all valve stem cores and be extra careful when removing the attachment from the valve stem.
I bought this product because I wanted a high quality, light weight, and compact hand pump; which it is. But I spent extra on it because I wanted a product that would make my life easier... That said, I don't know if there is a better product out there that meets all the criteria and out performs this product.

Comfortable to use, the pump reaches 90psi without undue effort but I imagine it would need a bit of heft to get much above 100psi. Lost count of the number of strokes taken to reach 90psi from a flat 700x35C tyre but this won't be your main pump and you can't expect a low volume pump to defy physics.
I would not be my choice to pump up a road tyre up to 100psi + with a mini pump, but It is possible with this pump & due to the flex hose connector the risk of damage to the valve is substantially reduced.
Not as good as a good frame pump, but a dam good substitute & looks very nice to!
