A customer brought in the rear wheel of a Bora One for repair.

The quick release lever stand came loose while the rear wheel was spinning,
got caught in the wheel, and broke some spokes.
Campagnolo quick releases have a characteristic shape on the lever side that
can catch shallow on certain stands,
and even a slight force can cause the stand to come loose.


↑This one
The spoke next to it on the same side (opposite the freewheel) was also deformed.



All fixed.


↑The replacement spoke


This is the deformed spoke that was next to the broken one.
By the way, I didn't discover this myself—
the customer pointed it out from the start.

This spoke is shared between front and rear left sides,
and since both use radial lacing, there's a small flattened indent on the hub end
to prevent the spoke from rotating based on the direction of the flattening.
This feature doesn't exist on rear right spokes.


Now, this is the spoke that was broken,
but naturally it wasn't originally a nipple-bent spoke.
A straight spoke got bent.
What's more, it bent at a nearly perpendicular angle
to the thin side of the indent—it's seriously kinked.
I'm not sure if it would bend this much even if you
swung a hammer down without hesitation on the hub end of a spoke
on a stationary Bora rear wheel.
This is serious force at work.
Alternatively, it might be possible to bend it this way using two pliers
to grab a spoke and applying static weight,
but with the spoke installed in the wheel under tension,
bending it to this degree would be nearly impossible.

When I first saw the wheel, what crossed my mind was
whether the carbon washer glued inside the rim holes had cracked from the shock,
but this time there was no problem.
I actually have an example where it did crack (→here).
