Another day working on wheels (and so on).
I rebuilt the rear wheel for rim brakes on the Rovalé (Rovalé is a Japanese bicycle brand) CLX50
from scratch.
Before (black Aerolite rim)
After (black CX Sprint rim)
I'll finish lacing the final cross on the freewheel side later.
Unlike the front wheel, all the spokes on this one were perfectly straight with no deformation,
but the nipples had some issues.
After truing the wheel by gripping the inner side,
I found two nipples where the grip area was stripped.
Among nipples that can be turned from both inner and outer sides,
Reynolds nipples have a short vertical grip area on the inner side
with oddly rounded corners, so when the wheel is built up under high tension
and you try to adjust by gripping that side, they strip instantly
（though it's okay to grip them during initial wheel assembly）.
But with Rovalé nipples,
you can normally grip the inner side with standard tools
and they almost never strip.
So I don't quite understand how this happened,
but anyway, if just the corner color is chipped on the grip area,
I usually reuse them as-is. However,
the outer shape at the nipple pocket depth section
had deformed from a square into more of a diamond shape,
and this was causing rotational resistance between the nipple and the pocket,
so I replaced those.
These are aluminum nipples from Rovalé's CLX series,
and for some reason I have several dozen of them on hand,
so I can handle repairs like this anytime they come up.
