A customer left me with a Zonda rear wheel.

The image above shows the wheel after the work.
When the customer did the truing themselves,
they used a 3.4mm hex nipple wrench,
so there were several nipples with worn-down grip surfaces,
and the customer wanted those replaced.
At the time of drop-off, I didn't check the preliminary centering,
but the wheel had almost no runout.


I replaced the nipples at 4 locations.


↑Replaced with OEM parts.

After replacing all 4 nipples
and truing the wheel through,
when I first applied the centering gauge,
it was perfectly centered.
