There is a nick just inside (below) the radius on the edge where the failure is. Do you know where or how it was created? That may have been the location of the force that caused the crack.
I don't know where that was created. I was given this bike for helping with some charity work. It had been sitting outside for several years. And a previous owner had done work like putting a shimano BB on (which was not a perfect taper match) and putting an english headset on.
I did have some loose chaing ring bolts, and lost one, but it wasn't the one on this locations....so hard to say
