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
Thank you for your feedback.
