Tiberi is quoted on CN saying "I had a mechanical problem, my crank broke, and so I thought it was all over."
'My crank broke' could cover a multitude of sins of course.

Looks like we got another one today, didn’t we?
That looked a lot more like a mechanic failure than a component failure.
The crank broke. I know some at the Italian team.

Sure looks to me like it means the pinch bolts weren’t done up properly...

Another one this morning. Bought from Evans cycles new about 2.5 years ago so I guess no point in trying to pursue it.

Is this an Ultegra only issue? - Cant remember seeing any broken 105 ?

Any failed R8000 or R7000 that "we" know about?
