Antti5 on September 5, 2025 3:29 pm Some time I answered “yes” to a similar question, and there were replies pointing out that some rims have concave braking surfaces from factory. Did you check if the braking surface has a wear indicator anywhere?
jeffbell on September 5, 2025 4:05 pm You see that dark groove in the middle of the brake track? See if you can poke a small screwdriver through that. That was the first indisputable sign that my rims were worn out. Some rims you can measure with [pointy calipers](https://www.amazon.com/Caliper-External-Straight-Measuring-Thickness/dp/B0DRTZHZX1), but on my old Mavic MA-2 rims, the hole went into the hollow part of the rim.

Pretty toast. I would look at replacing them

Only one way to find out;
send it down the Stelvio.
