Zonda

A customer left me a Zonda front wheel for repair.

They said it developed runout without them noticing,
and when I inspected it, it looked like lateral wobble
with some bent spokes mixed in.

I loosened the nipples and released the spoke tension.
They then remembered it actually started wobbling
when they did bike packing, which is hardly
"without noticing." Oh well, never mind.

In these cases, often just adjusting the nipple
at the replacement spoke location fixes it,
but there was still strange runout at that stage. When I looked closer,

I found another bent spoke near the hub.

I gave the customer the bent spoke near the hub
and had them try bending it back by hand
to see if it was possible. It wouldn't budge at all.
This shows the deformation that occurs under impact loading
cannot be reversed by static hand force alone.
