There is a lip on the inside of the ...

Assuming your cassette and freehub body are conventional, the cassette sits on a series of splines, and would be free to slide left/right if there were no locknut in the way. Since the hole in the cassette will be larger than the diameter of the freehub body, a missing or loose lockring will allow the cassette to twist out of the vertical plane parallel with ...

Maybe yours does too and suffers in the same way. What I've found is that the gauge can get muddy water in it, with enough grit to make the moving parts stick, either completely or partially (the latter cost ...

This is an interesting question. Without the pump in hand, only somewhat informed speculation is possible. All pumps have o-rings inside to create seals. O-rings are made of rubber, which can degrade with age - basically, it becomes less elastic, and maybe cracks. If your pump weren’t pumping entirely, there's definitely an o-ring inside the main chamber ...
