Makoti it might not work. You can put a shilmano FD in a 10 speed brifter but you cant put a 10 speed campy record in a 11 speed campy group.
If you look at the FD's the cable attachment lever is longer in the 11 speed, I imagine the 12 is an evolution of the 11 speed FD, so probably by association of facts wont work either.
Even the way you set up the FD in 10 speed and 11 speed is different because the levers work in another way, at least with chorus they got rid off of the ratchet, I imagine the 12 does the same than 11... would surprise me that they went back to ratchet tho....
U lose nothing trying and let me know tho
