A customer dropped off a pair of CADEX wheels with me.

I only took a photo of the front wheel.
That number 3.9 near the valve hole—
is that a note of the air pressure?
Without getting into specifics about the owner,
they said they used it in races overseas, like in France,
and wanted me to true the wheels.
I've trued this wheel a few times before,
but this time there wasn't much runout either.
Seems like they brought it in more or less on the side,
since they had other frame work done.

Anyway, setting that aside...



When I asked why there was sealing around the nipple-like parts,
they said it was to prevent water from seeping into the rim.

Anyway, with this wheel,
water gets into the rim pretty easily—
when you spin it at speeds below the point where centrifugal force would throw the water out of a bucket,
it makes these sloshing sounds,
like a drum washing machine spinning.

During the truing work,
that nipple-like part isn't actually a nipple—
it's "part of the spoke" that you just grab to prevent rotation,
you don't turn it.
The sealing isn't hard material either,
so when I gripped the contact area,
I could slide it down,
and it didn't interfere with the work at all.
