It is my understanding that I have a carbon fork on my Cannondale SR500. I have a scratch on the fork that seemed to scratch the top layer of paint only, and the layer underneath is indeed black which could be carbon or just primer. The area where the wheel attaches to the fork has the paint worn away and is for sure aluminum.

Can this piece be aluminum while the rest of the fork is carbon? The piece does to be separate from the fork.

I have dropouts (the aluminum piece) for fenders or rack on the front fork. Can I safely add a front rack if it's carbon?

Perhaps I am asking a bit much of my Cannodale but I'll create another thread for that.
