Shimano 105 5700 groupies on Pinarello F12
 

I just purchased an F12 frame and have a 105 5700 groupset. I had to upgrade the brakes as the new frame has dual mount. I'm pretty sure the frame has a direct mount front and rear derailleur. How do I go about making this work without buying a new groupset?

From the pictures on their awful website, it looks like a standard derailleur hanger in the rear and a braze on type mount in the front.

You just need to get a braze on front derailleur

If you want to be sure, put a picture of the lower seat tube in your gallery and tell us you have done that. Someone will rescue it for you
