im beginning to agree with both scenarios as you and others mentioned. I did think about the rim heat from braking but never thought that was a realistic scenario until you mentioned it. Below are screenshots from Wahoo/Strava showing the descent. Yes I did a LOT of braking and prior to the crash, and some of the curves were sharp despite how it looks on the map. Both may well have contributed to the tube working it’s way out, as well as inflation from temperature.
