this is my diy electric bike, but in the latest headset servicing (I had to change the seal of the top bearing), I noticed that I've a broken part on the top of the "bearing crown race stays".
The funny thing is that I found this picture of 2 years ago where the damage was already there, but since I was a noob about bike maintenance (and still I'm, but a bit less), I ignored that. The picture was made even before the conversion.
I did 5000km since then, and I didn't noticed any play in the headset, but is it safe to ride? What I should do to mitigate/fix this? Can this broke catastrophically someday? the bike is 10 years old.
This is the bearing crown race that goes on the bottom of the fork, and I can slide with my fingers easily, but still no play in there, as far as I can feel. This would need a replacement as well but I cannot find in the internet, this is a weird 1 1/8 threaded fork.
