But, I have also used it so vigorously, carelessly, and without securing the wheel against something because I'm lazy and in a hurry.......that not infrequently my 5)#@+ pumping causes partial separation of stem from tube----pppssssstttt! Try patching that one.
Betcha nobody else here does that.
A couple of months ago, I watched guys fixing a flat destroy a tube that way, and about the same time read something about how easy that is to do with a frame pump, and that made me decide to upgrade my frame pumps to Topeak Morphs, which have a hose and operate like a floor pump. I already had one frame pump with a hose, now I just need two more, and one is one the way.
