One overlooked problem with these floor pumps in general is they operate in opposite fashion in terms as how to connect to the valve. My Lezyne pump requires the nozzle to be perpendicular when attached to the presta valve and you then lock it to the valve by flipping the lever so it is then parallel to the nozzle before pumping. To detach from the valve you then must flip the lever perpendicular before removing. Other pumps operate in the opposite fashion. Last night, I mistakenly attached my pump to the valve when it was parallel to the nozzle and it caused sealant to explode out of my tubes. Also the threaded nozzles should never be used on removable presta valves. I ended up pulling out my valves several times and got a face full of sealant after it exploded out of my tubes. A quick release nozzle is a must for removable valve cores.
I have the same pump, Alloy edition. No problems in 4 years; I just put a couple of drops of air tool oil on the piston shaft 2-3 times a year which seems to refresh the (non-servicable) seal just fine. As for the removable valve core issue, it's always a good idea to secure those puppies with a dab of blue threadlock, or even easier is to use Teflon plumber's tape (about 3 bucks at the hardware store) and wrap the core threads (male side) with a short section (3-4 cm) which will make backing out the core way less likely. A good review of a really good pump (and, yeah, Silca are the bomb).
I have the Micro Floor Drive attached to my bike and I've had the same problem when unscrewing the chuck and unwittingly backing out the valve core, which is extremely frustrating when fixing a flat on the road. I now prevent that by having a valve core tool with me and tightening the valve core before screwing on the chuck.
So, my 2 year old Lezyne ABS floor pump lost pressure. It's always been in a heated garage during winter. Probably been used a total of 15 times. I used it on my bike, and snowblower tires. How can this $$$ pump fail after a very short period? Yet the cheap $20 floor pump I bought at Walmart 8 years ago, keep in the outdoor shed which goes below freezing during winter, still works? Last pump you will ever buy? Yup, last Lezyne I'll ever F'n buy!!!!!!!!
I had the same issue after a year or so of perfect operation. No pressure and heaps of pumping until around 20psi when the back pressure seemed to help seal the piston, in which case i was well and truly over it. The screw on valve connection is the best design feature of this pump so I was determined to make it work. I figured the heat had made the grease dry out so used a home made pin tool from wire to unscrew the top shaft collar and re-greased the piston and O ring. This seemed to help but next time around made little difference. Factory service video says very little grease required and suggest swapping the piston O ring with the free spare O ring above the piston which acts as a bump cushion when you pull up and extend the shaft to max. I finally solved the problem by replacing the piston O ring with a fatter section O ring from a local bearing shop. Try a BS210, BS211 or even a BS212 will work although it is a little large and needs to be eased into the tube.
I just found one of these in the skip, looks almost new. Online, about £70, but if its gonna be a hassle with valve bits coming out and pressure problems, its worthless.
Based on this review and others I purchased this pump and I hate it. The "air bleed" is a bit of misrepresentation by Lezyne. It only works for schrader. For presta if you push the ABS button to let out air, it only is letting air out of the hose, not out of the presta valve. So when you screw the head on to the presta valve of a tire that has 50psi in it, the lezyne pump will read 0psi. You slightly push on the pump handle and at this point the pump tube pressure is pressurized and it opens the presta valve and will read the correct pressure. But if you pump up to 60psi and decided you want to be at 55psi and push the ABS button to bleed some air, it will instantly go to 0psi because it is letting air out of the pump hose, not the tire. I understand why it does this, but my Topeak pump was able to bleed air out of a presta valve with the push of a button.
bad product, bad engineering, bad component quality in relation to the pressure gauge with FAILS for a majority of buyers. Sucky experience and never a Lezyne again EVER
There's another Lezyne-produced video that explains the air bleed system. For Presta, it releases pressure from the chuck itself to make unscrewing it easier. For Schrader, it releases pressure from the tire. This is the stated design so there's no misrepresentation by Lezyne.
@@psycholist724 yes I know this now after I purchased it. But it wasn't clear in this video or in many other documents and videos. This pump is just of low quality anyway. The wooden handle on mine fell off within of month of purchase.
@@shanefrank3281 Crap, well I just ordered one so I hope it's better. I've been so frustrated with my other pump especially with so many of my valves being fully threaded, I figure it'll be easier overall to get the threaded chuck, even if it takes a bit more time to put on. Also many of my tube stems are quite short but still have a threaded valve core so the threaded chuck will be far less of a hassle than the traditional pump head on my other one. (I hope so, anyway.)
@@psycholist724 The chuck actually works quite well and is likely the best one out there for short tube stems. The only issue I have had is a few times it has removed removable cores when taking off the chuck, but that has been rare. The pump has been durable except for the handle.
That is not what the ABS does. It releases the air from the hose so you can get the chuck off the valve easier. It will not let the air out of your tire.
mine came with a quick attach/release valve that allows you to simply push the valve onto the tube valve. Should solve the problem of quick release valves
I have the high performance floor pump with the metal handle and screw on presta/shrader at a 90 degree angle. I’m able to screw it on okay after tapping the presta valve, and after a couple of hard pumps to start the process. It feels like breaking a seal. BUT too often the process of unscrewing the pump valve also unscrews the tube valve. It’s insane! How could this major design flaw have been missed? I’ll probably try to contact Lezyne since I actually bought it when Performance was closing down its brick and mortar shops. In the meantime, do you have any suggestions on a way to remove these valves in a way that is less likely to remove the valve? Maybe pressing or pulling while removing?
The gauge flew apart after four summers and I don't ride that much 69 years old. Had a cheapie pump for 20 years sorry I threw it away now they want $45 for a new gauge plus tax plus shipping cost almost as much as the original pump. I wasted my money trying to buy a good pump to last me. The give you a nice CNC pump with cheap plastic parts that need replacement
Good review, Thanks., My Lezyne High volume pump gauge does not work. I have had the pump about 1 year. How did you get your problem with your gauge fixed by Lezyne? Thanks
Thanks for making this video for others. My lifeline floor pump is now pushing air out as soon as I reach 50 psi, it use to go up to 120 psi. Its 4 years old. Does that mean I need a new pump?
got the fancier one in 2020. Can not tell you how much i HATE this. And i feel guilty for hating it, like I'm just incompetent. I dont even think it fits the tire on a BMX bike I have. It takes me 4 minutes to get the end into the mountain bike tire with all the awkward positioning, screwing in, air trying to escape. I HATE it and it was so expensive, dont even know what to do with it. MAYBE the clever engineers could make yet ANOTHER piece or two to solve the attachment issues.
Pump of very poor quality, begins to be faulty after 3 months, total loss of efficiency in 1 year. Pretty pump but mediocre quality at high price, even fleeing the low end will last longer.
I just bought Steel floor drive. I asked for most durable pump in bike store. If this one fails I will never ever buy another pump. I will pay up to 200 $ just to get a pump that can operate 1000 times, but it looks like pump industry is bunch of idiots with no engineering skills. I'm sick and tired of shity pumps, that brake apart after 5 uses. If I get 100 uses of my Lezyne i will let you know.
Pump is working fine after 100 uses, I only put little shimano grease on piston every year. Very precise for road bikes at high pressure, but not as fast as SKS orange pump for high volume MTB. I also found a great mini pump Topeak Micro Rocket. All three are money not wasted.

Does a lot of air escape when screwing off? I have a compressor pump that hisses so much as I’m unscrewing. It takes s lot of screwing too.

@@vivaparenzo you must be one of the rare people on whom the gauge has not failed and locked out within weeks. Terrible Terrible experience
All pumps are rubbish nowadays, literally not one good pump out there, no one knows how to make a pump anymore.
