A customer dropped off a Bora One rear wheel with me.
As you can see, the spokes are completely snapped.
Five spokes broke on the freewheel side — 1, 2, 3, 4, 5 of them — and
the sixth spoke didn't break and stopped it here.
Plus, while not bent,
there was one spoke that had come loose from its nipple connection at the hub.
Apparently it was from a crash.
Since the rim itself is undamaged (no rim hole damage or sidewall cracks),
it should be fixable just by replacing the spokes,
but this rear wheel is a tubular rim, and the tire is glued on with rim cement.
If I dropped a nipple while replacing spokes,
I'd have to strip off the tire.
Also, if I'm only replacing one or two spokes,
the remaining spokes act as guides for lateral truing,
so I can replace them without introducing runout,
but this time I'm replacing freewheel side spokes across almost half the circumference,
so if obvious runout appears, I'd end up stripping the tire anyway.
(Contrary to expectations) I managed to fix it without stripping it.
The spoke marked with tape,
from the bottom of the image going counterclockwise up to the sixth spoke—
those are all the snapped and bent spokes,
and the seventh spoke a bit further along hasn't been replaced, but
I did loosen its nipple temporarily to reset the hook.
With adjustment to just these seven places,
in simple theoretical terms,
we should be able to restore it to the state right before the crash,
and it turned out even better than I'd expected.
For the centering gauge, I'm using Park Tool rather than my usual Hozan,
since it can be used with the tire on.
