But (and this is, to my mind a very big but) that Lyzne is short. Long stroke pumps pump get there with fewer strokes. I will admit I haven't used the Lezyne but I have trouble with the concept that it would be easier than the Zephal HPX. And Zephal gets that longer is better and supplies the pump in four lengths so you can fit the longest possible on your bike.

The HPX. Not a hot new name, no flash, just a pump that will fill your tires easily many, many times. (I had the predecessor, the HP on my bikes in my racing days and no other pump. Maintaining sew-ups on all my bikes with just those pumps was no big deal. It was 18 years before I bought a floor pump. I used the classic digital pressure gauge that most of us have lying around somewhere. Thumb and fore finger.)
