DTSwiss rear wheel hub part name I want to buy a used bike (Specialized Tarmac) with good price
But rear wheel hub is broken as in photo

What is a part name I have to buy and change, or it must be completely changed
PS: I don't know exact model name, but on it Ultegra 67xx 11 chains

UPDATE:
The wheelset model DT Swiss Axis 3.0
The part which is broken is called the flange of the hub, however these aren't replaceable. You'd need a whole new hub or wheel.
