A customer brought in the rear wheel from a Racing Quattro Carbon (Japanese carbon racing bike) for repair.

A spoke had broken, so they wanted it repaired.

The break is at the boundary where the butted section ends.


This wheel had been serviced at our shop before,
and I swear I didn't apply it myself,
but there was a mysterious sticker on it.

Being prepared always makes things better



I adjusted only the nipple of the replaced spoke,
and once the lateral runout at that position was gone,
the wheel was nearly runout-free overall.
When I finally applied the centering gauge,
it was dead on.
Apart from the replaced spoke's nipple,
I only turned two other spots just slightly.
It took far less time to fix this wheel
than it would to true a wheel that shipped
without decent accuracy.
If you can trust the original condition, that's how it goes.



All fixed.
