A customer dropped off the rear wheel of a G3 version racing Quattro-style wheel for repair.

The "CX" designation means it's designed for cyclocross, and this model has
a token amount ofwaterproof sealing added to the bottom bracket cup and wheel.
Anyway, moving on...


A spoke is broken.
It appears to have been caused by the rear derailleur getting tangled up in it.


There are other spokes that need replacing too, so I'll swap those out as well.


The nipples are the type that can be turned from the outer edge as well,
and they're used together with a dedicated nipple washer, but...


The nipple somehow sits stable at an angle.
It's not that the nipple bent from the impact of the derailleur snag—


The problem was with the nipple washer itself.
The relationship between the cupped recess and the hole position is eccentric.



↑Like this
Since this is the nipple washer from the bent spoke, I can't tell
if it was made that way originally or if the derailleur snag caused it.
When I applied spoke tension with this nipple washer,
the nipple was guided by the tension and... didn't straighten out.
Since this is the freewheel side of the G3, flipping the nipple washer
front-to-back doesn't change the spoke's trajectory or angle in a favorable way.
In the end, I replaced the nipple washer.


Fixed.


The tape I applied marks the replaced spokes.
I put the tape on to make it easier to focus on adjusting only the nipples
at the taped locations, and to fine-tune things until the largest runout
is no longer directly under a replaced spoke.
