This Pinarello Derailleur Hanger is the part that you'll need for your Dogma 65.1 Think2, Dogma2, Dogma, Prince Carbon, and 2011and 2012 Paris Carbon. It has a well-thought-out design that we really like. The part that we like is that the hardware threads into the hanger itself instead of into the dropout. The benefit comes on the fateful day that you lay the bike down and mangle the hanger. Your high-end bike frame will more than likely be unharmed as the hanger will take all the abuse, and it's a simple (and inexpensive) fix.
The Pinarello Derailleur Hanger is black and made of aluminum. It comes with the necessary hardware for installation.
