A customer brought in a rear wheel from a Vittoria Corsa 46 for service.

As you can see,

a spoke is broken.
It happened from a crash, apparently.

Fixed. With the spoke removed,
as long as you're careful not to drop the nipple inside the rim,
you can replace a spoke without removing the tubular tire.

In situations like this, by adjusting only the nipple of the replacement spoke
and truing it as much as possible,
we can essentially recreate the state just before the spoke broke.
If an emergency repair was done at the roadside where the spoke broke, that's different,
but otherwise, by looking at the temporary center from that state,
you can tell if spoke failure was already happening before it broke.
I did the same thing this time,
and the spoke adjacent to the replacement (two rim holes over on the same side)
was quite out of true, and when I touched it, it felt dented, so I released the tension and

↑it was like this, so I replaced it.
By the way, this spoke is a straight-gauge black CX-RAY version,
and it was brought to us for two reasons:
the Vittoria distributor doesn't supply spare spokes as individual units,
and the customer heard about our notorious reputation from an acquaintance.
