A customer brought in a 9000 WO rear wheel for repair.
Apparently some shop attempted a truing job on it,
and gave up after the rim ended up with severe radial runout that couldn't be corrected.
At least they didn't charge for the work.
The lateral runout was addressed "only" somewhat,
but the radial runout was so bad you could see it by eye without even using the truing stand.
When you spin the wheel, the rim pulses and throbs with each rotation.
On top of that, there was centering issues.
The rim being shifted this far toward the freewheel side isn't from factory defect or normal wear—
it's purely from someone tinkering with only the lateral runout.
After working on it, I found the rim itself had no damage,
so I was able to true it normally until the radial runout was less than a new out-of-the-box wheel.
The center also came out perfectly.
Apparently someone told them "the rim is bent, replacing it will cost ¥35,000,"
but this experience shows that what looks like a bent rim is really just poor adjustment.
