I've used this pump twice on my road bike and I was impressed at how quickly I was able to get my tires to 80-90 psi. I don't know if this makes any difference, but I was inflating a 'Slime' inner tube and I didn't have any problems. I really liked how you can screw the pump onto the end of the presta valve - maybe all pumps offer that feature and I wasn't aware of it, but this was a real difference maker for me. Very light, easy to get it on/off the bike - I'm a fan.
I was not wearing my reading glasses , and didn�t scrutinize the listing.
I wanted the micro xl model.
I realized immediately that I had ordered the wrong pump , but I decided to try it on my 29x 2.6 tires .
To my surprise it almost seemed better than the xl .
It is easier to pump, just more pumps that�s all .
I have had two of the micro xl pumps for my fat tire and plus tire bikes and for the money they don�t seem to last that long before the anodizing starts to where out on the shaft .
And Lezyne doesn�t warranty it either .
Hopefully this model will wear better .
Had another lezyne (Gravel sport with the tubeless chuck) that came loose at the base where it threads in. Otherwise like Lezyne pumps. This one is very solid and no issues. Also like the presta (which I use most) and schrader head since I do have one bike that requires that. Fills the tires with air, no frills, no problems. Even used the old tubeless to help a friend mount some tires w/o the compressor. The solid steel shaft was stable and it did the job.
When new, it's great. The pump head seals perfectly and can handle very high pressures. The release valve on the side makes removal easy, too. The main issue is that the threads are aluminum whilst most presta valves are steel. What this means is that any misalignment can easily lead to cross threading, which will immediately destroy the pump head threads. The pump head still works, but now there's always a risk of loosening the valve core during removal of the pump. I will be switching over to the lever style pump head.
