Trailside Review – Lezyne Pressure Drive Mini Pump

20120225-124051.jpg

Lezyne’s Pressure Drive mini pump is a CNC aluminum mini pump that claims to go to 120psi. The overlapping barrel and handle with a detacheable threaded hose makes for a compact package that easily slides into even the smallest hydration pack. It even does well inside a jersey pocket alongside a tube to keep it from bouncing around or sliding out too easily.

Lezyne claims the oversized barrel reduces the number of strokes required to fill a tire. I didn’t keep count, but getting a tubeless mountain bike tire or cyclocross tire up to riding pressure wasn’t terribly laborious. Filling a road tire wasn’t as much fun, which is sort of a shame because it does fit so well in a jersey and it’s really lightweight. That said, it’s far better than some other compact pumps I’ve used.

Fill up with the details after the break…

The ABS flexible hose threads onto the valve stem and has Presta on one end and Schrader on the other. Because it’s not a fixed part of the pump, you can really put some elbow grease into the pumping without fear of breaking the valve and ruining your ride (or at minimum your tube).

The threaded attachment has a pressure release valve to let air out of the pump hose before removing it to ease the release and keep it from popping off. The downside to threaded attachments is that they tend to pull removable valve cores with them, letting all your hard earned air right back out.

This problem isn’t exclusive to Lezyne. Some of their pumps include adapters to simple press onto the stem, so you could order one of those with your pump. Or you could get a threaded Presta-to-Schrader adapter and use that, but it takes away a little of the magic. And press-on tips aren’t going to stay on as well during vigorous pumping. A better solution is to get tubes or tubeless valves without removable cores, which is what I’m slowly replacing all of mine with.

When you’re done, you simply unthread it, slide it into the other end and thread it in flush:

Even with my large hands, it was comfortable to pump and didn’t heat up too much. Action is smooth and tight, it feels well constructed, and no air leaked out around the valve. It’s become my default pack pump.

The Lezyne Pressure Drive comes in gold (tested), black, red and blue and retails for $44.99.

new version has pressure release button on hose to negate valve core issue

Great pumps, but like you said, it can be easy to remove the valve core when unscrewing the hose/head. When I install a new tube/valve, I always tighten it with a Stans valve tool.

This type of hose do not fit to some threadless presta valves used in aerodynamic rims (road bikes). You can see an example here: http://dpedal.files.wordpress.com/2012/02/bico_presta_sem_rosca_p.jpg . The best is to replace the tube since the pump is very good.

I put lube in mine when it does that. I usually ride tubeless, but from time to time I borrow a friends bike or someone has a flat and it gets used. Overall, it’s near perfect for what it’s made to do.

I like Mike have been doing the same. I always tighten the tube before I install them or toss them in my saddlebag/jersey. I havent had a problem when I do that. Love my lezyne pump.

Won one of these as a prize. Has been okay. Nicely made. Like all these pumps it is slow going. It does look like it will last.

I have had one of these in gold for about 3 years and its still holding up strong after traveling to croatia france austria australia california its my trusty little pump although it does take a while to fill a mountainbike tire up to a good pressure I usually go to a bike store to still use a floor pump when traveling before hitting the trails

This particular pump is designed for road tire inflation. They do make pumps that are designed for mtn. use.
Lezyne Designates the HP (high pressure) pumps for low volume tires and HV (high pressure) for big tires. If you think that pump works well check out the alloy drive line of pumps!

Is it really a surprise that you can’t completely fill up a tire with a hand pump? they are to help you limp home, not be your only source of putting air in your tires. Be sure to have a nice floor pump at home and top off before every ride

captainmorgan - 02/27/12 - 10:49am

Yes, definitely do not use the Pressure Drive on a mountain tire, you’ll be there all day. I have an HV Alloy Drive for the last year and its been a great little hand pump. light, efficient, and the flex hose is key. Its a bit pricey though.

I’ve wanted to also get a Topeak RaceRocket http://www.topeak.com/products/Pumps/racerocket_red and give that a try for comparison, since its virtually identical, but does have a nice rubber hand grip, which the Lenzyne does not.

Lezyne’s Micro Floor Drive pumps are true replacements for a floor pump and are nearly as small.

Scott Ender - 02/27/12 - 4:50pm

Hey all,
Just thought I might try and clear up any confusion that’s going around about Lezyne pumps. Any Lezyne pump can pump up just about any tire in any size,….. it’s just a matter of how quick the going is and how strong the user is. Yes, the Pressure Drive is not ideal for pumping up a MTB tire, but it will work great and get the job done. An HV pump is ideal for MTB use, yes, but an HP pump works too. Our Road Drives pump to 160 psi, but it’s a simple matter of whether or not the user can get it there.

Our pumps have been know to pull valve cores, but both tightening the removable core as well as using our new ABS features on our hand pumps should solve all problems involved.

Scott

can you give a rough approximate example as to how much longer a HP will take over an HV in a MTB tire?

*Pro and con of using a HV in a Road tire?

* What are these new ABS features and will I get them in any pump i order now?

Thank you

Yesterday my Lezyne pump got stuck on the valve and I couldn’t get it loose so I had to walk for two hours to get home. I had to cut the valve with a Dremel to get it off the bike.

Kb4iuj - 06/17/14 - 2:46pm

I have one, would I recommend anyone go out and buy one? No. I’m happy if it pumps out 30 pounds oh,wait maybe 40 at best. I learned a valuable lesson, don’t buy anything from the bike shop that sold me it.
