Take a look at the picture attached and you will see that the area on the rim where the spoke enters has been rubber away and close to it is a white area where the top coat of paint had been removed.
It is like this all the way around the rim.
It is only on one side and only where the spokes that are on the outermost on the chain side.
I first noticed it last year and the marks were about half the size of what you see today.
Over exuberant cleaning was suggested, but I don't think that is it because I don't clean it that often and I tried to make it worse by rubbing hard with a dry cloth and I couldn't.
There is nothing anywhere near the rim which could rub.
Suggestions appreciated.
