It broke off like this.
It's a GIOS Mistral that I've had for 10 years, so I went to the store and was told I had to order it back.
So I looked for it online and found it for sale on Amazon! As you can see when you go to the link, they also sell derailleur hangers in other shapes.
When compared, it is a mirror image of the original one.
Of course it was a perfect fit!
Everyone, please don't give up and search on Amazon when it breaks. I hope the above will be helpful.
