I received a Ksyrium SLR from a customer for service.
The rim centering was seriously off on both front and rear wheels.
The enclosed letter didn't mention it,
but I suspect the wheel was sent to us because
the customer noticed this issue.
Regarding the expression "off-center," there's a range of severity
from worst to least severe:
・Seriously off
・Barely noticeable
・Detectable with a gauge
・Acceptable for factory shipment
・Like a wet puppy
Also, the rear wheel spoke tension was clearly low,
and the rim was shifted toward the freewheel side.
The freewheel side—which I don't want to tension—needed tightening,
while the non-freewheel side needed loosening or no adjustment.
As a result, I first increased tension on the freewheel side considerably
until the rim shift actually reversed, then applied a slight increase
to the non-freewheel side.
I'm not sure if it was like this from the factory,
but when it arrived, the freewheel side was definitely too loose,
and since I was able to tighten it quite a bit,
I believe it was loose from the start.
（If the spokes were already properly tensioned, I wouldn't need to tighten further,
and honestly wouldn't be able to tighten much anyway.）
To adjust the non-freewheel side nipples,
I need to remove the spoke protector ring.
Since I couldn't fully dial out the runout with just freewheel side adjustments, I removed it.
I cleaned everything while reassembling.

↑Before installing the spoke protector ring back on,
I apply noise-prevention grease to the spoke heads.
Water-resistant grease works best for this,
and this is what we use at the shop.
Oops, I forgot to take a photo of that step
I've written before about Ksyrium spokes—
the older design has a transition from round to flattened cross-section
that looks like a fish tail, with a wide flattened section,
while the newer design transitions like standard aero spokes
with a narrower flattened section (adopted from the Ksyrium SLS onwards).
However, the transition wasn't complete across the board—
sometimes they mixed old and new designs between front and rear wheels.
What's interesting is that
while the Ksyrium SLS has the new-style front wheel and old-style rear wheel,
this Ksyrium SLR has the opposite configuration:
old-style front wheel and new-style rear freewheel side
（with Traco carbon spokes on the non-freewheel side）.
