For a drop-out hanger on a carbon bike, a person should try Calfee. With the repair service, they may have seen this in the past. Certainly they can fabricate Al and Ti bits.

Maybe I should post detailed pics of my TetraPro, But I don't think of it as vintage carbon; 130 rear, threadless fork, sporting Campy 10speed, I think of it as my modern carbon bike. Sub-20# in size 60 with bottle cage and pedals. Frame = 3.0lbs. 5 years left on warranty.
