As a by the by, if you wanted to persist with the idea of putting a rack on the back of CF frame, look at actually using epoxy and make up the required braze-ons/eyelets. You may need to have the courage to do it, and undertake some research so you can get it reasonably right, but done properly, the set-up would spread the load along the seat or chainstay.
