I received a Racing Zero from a customer.
It's not like I rushed to do this today just because someone nagged me in the comments yesterday.
Both the front and rear wheels have lateral runout, and the rear wheel also has radial runout, so the customer wants repairs.
They mentioned that it might be from wheel transport to Okinawa,
and from what I can see, that does seem to be the case.
Starting with the front wheel, there's a seized nipple that won't turn.
With free-side spokes or in the case of Mavic Ksyrium spokes,
you're stuck at this point.
Since the front and rear non-drive-side spokes use spoke nipple connections,
I gently tapped out the spoke head
With the spoke tension released,
if the nipple still won't turn, you're stuck for sure,
but somehow it did turn, so
I replaced the nipple.
It happens occasionally that I need to replace nipples that aren't even stripped, for this reason.
The sticker on the front rim was peeling like it got bumped.
The whitened part looks like a dent,
but the seal was just gunked up, so there's no problem.
Conveniently, I had this wheel's sticker in stock,
and specifically the front wheel version only, so
Instead of a complete replacement, I just replaced this section.
The rear wheel has severe radial runout.
This Racing Zero has a rim hole phase that's somewhat G3-like,
and when I set my truing stand gauge right between the G3 spoke bundles,
there's a gap between the rim and the gauge directly below the G3 bundle,
as shown in the diagram above.
This is "structural runout that can't be helped," but
this rear wheel had radial runout toward the outside at 2 out of 7 mid-phase positions,
which went beyond the "unavoidable" category.
The customer had also pointed out
a suspicion that there were bent spokes mixed in,
and upon careful inspection,
2 spokes were indeed bent, but
1 spoke actually snapped when I forcibly turned the seized spoke — snap!
I also replaced any seized-up nipple candidates I spotted.
I did as much truing as possible, though it didn't quite reach like-new condition.
I've brought it to the point where there's virtually no noticeable runout and it's completely safe to use.
I cast my secret cleansing technique on it,
before
after
It came out looking pretty nice.
The customer mentioned they were handling the hub overhaul themselves, and from what I could feel, there didn't seem to be any need for me to get involved,
but since they mentioned the freewheel body claw return spring was looking suspect,
I did check that. No replacement needed.
