A customer dropped off a Zonda rear wheel with me.


One spoke is broken.
This is a Zonda from the C15 rim era, built with G3 lacing but
with the spoke tension weighted more heavily
on the freewheel side.
The later C17 rim version of the Zonda
was built with equal diameter spokes on both sides
to match the non-freewheel side,
so the spoke specs are different.



Fixed.


↑ The replaced spoke


The straight spoke has broken just below the head.
This isn't from external causes like something getting caught
or a crash—it's just a normal spoke breakage.
Though I say "normal," this is actually an extremely rare reason
for a spoke replacement.


The deformation of this spoke came from the spoke bouncing inward
toward the rim interior at the moment of breakage,
causing part of the spoke to get pulled into the rim.
Back when I was doing night training runs on the Hannan Expressway downhill,
one of the front wheel spokes on my Nomu Lab Wheel #4 broke,
and almost the entire spoke got dragged into the rim.
I had quite a time getting it out.
That time, I rode the bike back to the shop on my own
and finished the repair the same day.
