You mentioned more vibration in the stand than normal, does this also go every other gear?
Independent of front ring position (assuming not 1x)?
You torqued the lockring, did you verify he sprockets are tight as well, IE don't move by hand?
Condition of the freebody? IE, not all grooved up like the cheap early aluminum ones.
Does the noise occur in the stand when turning by hand? What if you drag the brake to induce a load? I assume it's gone when coasting, but does it happen under medium load, light load? Does it change?
No.
Doesn't appear to be.
It's not every other gear exactly, but just some random gears mostly toward the middle.
It is louder in the big front ring.
Yes, lock ring is torqued, no play in cassette.
Freehub body is in great shape.
Happens under all load. Obviously far more noticeable while pedaling, but if I run through the gears by hand, I can tell which ones get louder. This was what confirmed for me it's unlikely to be movement in the cassette, because my hand turning the crank might be 1 watt, which wouldn't be enough to twist the cassette unless it was very loose.
