As with most Lezyne products I own and use, headlamps and frame pumps, this has some nice features and some problems. The overall balance falling in their favor.
Example one. The gauge is large, easy to read and well protected by base. It is also easy to replace and parts appear to be available. On the negative, it has a tremendous amount of friction and tends to peak hold at 5-10 lbs above the tire pressure unless you tap it, or top out the piston for the next stroke.
I really like the long hose, it is long enough to pump tires on stand, and with slight tension the head hooks into a retainer in the base, effectively constraining the hose, handle and plunger. I do not understand the additional clips at the top which will probably dramatically shorten the life of the hose by fraying the jacket, and are seemingly redundant.
The controversial part for most people is the screw on nozzle. It works well, I find it easy to use, so I don't mind it.
The plunger seals well, the stroke is long, and the diameter is such that it is a good combination of volume and force for road tires. Mine has developed a wheeze and slight scratching as I pump. I am going to open it and see what up.
I am using it and hoping the the sticky gage wears in and reads more accurately, and going to see if the noisy pumping is a lubrication issue, or something else that is easy to fix. After that I guess I decide whether I keep it or not. I like the basic design, the look, the long hose, the big gage and the availability of parts. Not sure if the problems balance that out.
I have been a regular customer for 9 years, so I've got to mention that I tried to ask about the gage issue, but the phone went unanswered, and a follow up email has not been answered for over a week now. Customer service from BTD has always been good before and I am disappointed
I the pump to appear to have great engineering and design details however upon use I found rotating the barrel attachment to the valve stem difficult because of the finger force needed to rotate to a tight position (which my wife gave up on and went back to the old pump) and the barrel will not fit over a valve extender. So basically I can't use this pump. Looks nice sitting in the corner...
The mechanism for screwing onto the valve stem has worked really well on both presta and shrader. This pump is faster to inflate a tire than my old Joe Blow pump. I've been pleased with it.
I've been using the Schrader adapters to fill my road bike tires because I was disgusted with the friction type Presta floor pumps. It wasn't till I went over to my riding partners house and saw his new Lezyne floor pump and was impressed with the quality. I especially like how it threads onto the presta valves and the pressure release button on the side. I believe it should be the last floor pump I'll need to buy.
I like the screw on inflation head rather than the flip on, it takes a few more seconds but provides a secure connection, the relief valve also is nice to fine tune your pressure exactly, and the gauge reads easily.
The fit and finish seem nice, but pumping action seems just a bit spindly such that it almost feels like one could bend the pump arm if you don't go straight up and down. Overall, though, it is a nice pump.
If you are looking for a reasonable priced tire pump which does what it advertises to do, and you want a specific air pressure, this is the pump. It is as precise as the digital version with no needs to worry about batteries.
