A customer dropped off a pair of front and rear wheels for Zonda (a wheelset with C15 narrow rims).
They wanted the hub and rim label cleaning, and roundness check inspection.
↑This is the front wheel after work,
and the center was perfectly aligned without any deviation.
There's essentially no runout either.
The hub components on both wheels showed no damage,
and there was hardly any dirt at all.
While there are brake marks on the brake zone,
so it's not brand new or unused,
the overall condition is excellent.
↑The rear wheel also had perfect center alignment and essentially no runout.
The precision is so good that I wondered if this was either
an exceptionally lucky specimen or a wheel that had been
inspected by another shop and sent in for re-inspection—
there was literally nothing wrong with it.
Regarding Campagnolo rim labels (stickers),
with years of use, or if you continue using mounting methods that hook onto the rim,
the surface film tends to peel or chip off.
Where the film peels, the adhesive remains sticky,
and it attracts dust, causing the area to look black and dirty.
When you wipe it with solvent like parts cleaner,
it looks clean for a moment, but it quickly gets dirty again the same way.
If that happens, if replacement stickers are still available,
it's fine to stick new ones on, but otherwise it's cleaner to just remove them all.
However, this time there was no film peeling—it was just a little dirty.
Chain oil is the main culprit for the dirt,
so the right side of the rear rim gets dirtiest.

Both are the same areas respectively.
Since this is a rim with no holes except for the valve hole and there were no tires on it,
I masked off the valve hole before washing.
Since there was lots of other stuff to wash, I cleaned about 4 pairs including this one.
