[TR] pully failure

 Yep. Had the same thing happen to me.

I went through several attempts to find good pulleys.   Most of the ones I
found when sanded and cleaned up had cracks in them.   Based on this - I
have to believe it's a fairly common occurance.

Others had wollwed out holes.

In my opinion,  I think over tight belts over time are the culprit for
this.    Still think it's a bit strange to have a pressed sheet metal pulley
on the crank...

Might be time to consider a narrow belt conversion.   I could not find a
source for new inner pulley when mine failed 2 years ago.
