... the sound was actually getting worse and was becoming a loud creaking rather than clicking. The sound was clearly audible at >200W and >80RPM and it sounded like my bike could break any moment for >400W and >80RPM.
To me this sounds like the stereotypical Bottom Bracket / crank interface although I have not wrenched in ages other than my own bikes now.

I use Campy and have UT and threaded english BB for 2 bikes. On one bike I have no issues (I measures everything before installation, etc). On the 2nd It has the exact same >200w / 80rpm clicking noise which gets worse at higher torque times. If I double pedal I can minimize it. Light smooth pedaling .. nothing. heavier pedaling .. clicking.
With Campy UT it's a fixed width so one can calculate stuff out, although a major PITA.

But someone mentioned hambini. he has identified that the two sides of a BB interface may not be perfectly directly across from each other, thus causing the crank/axle to be slightly skewed in relation to the bearing/cups, thus causing what seems the correct installation to not really work no matter what you do.

With regards to misalignment.

This was the worst I had seen up to that point. https://www.youtube.com/watch?v=rtsos05Bf3U

I have seen a cervelo with worse since. And canyon also have bottom bracket halves glued together so they may well be misaligned.

At this point my best bet is that the BB shell is damaged from the crash I mentioned in the OP.

So you think that you broke your bike through your own misadventure, and therefore you want to sue Canyon over it.

What the *f##k* is wrong with you? :noidea:

I forgot to add. Shimano hollow cranks start creaking before failure too under load, although you stated you installed new cranks.
