A customer left a Bora rear wheel with me.
Since it's a clincher, I was using the higher-precision center gauge, and when I removed the tire, it was rattling quite a bit. I thought maybe a nipple had fallen inside the rim.
I've seen a Campagnolo Shamal (not Shamal Ultra) before where during wheel building, someone dropped a nipple inside the rim and thought "I'll retrieve it later," then just replaced the nipple and continued working, and never did retrieve the lost one. There ended up being one extra nipple loose inside the rim even though none were missing from the spoke count.
But this time, that wasn't the cause—it was a spoke neck breakage on the straight-pull spokes. The customer said he'd only used it about 500km since purchase, so you could call it a manufacturing defect. Rather than go back and forth with the shop where he bought it, it seemed faster to just fix it here in our workshop.
↑ The adjacent spoke position for reference—this is the normal condition
I replaced the spoke.
