That's too bad because I don't think their mountain front derailleur is designed for larger road chainrings.
Shifters on the other hand can go on any setup.

I am hopeful that the mtn triple FD cage can be modified to work with road rings. An expensive gamble unless one had a backup plan to use the Di2 mtn group if it did not work out. Even if modifying the FD works there is also the gamble that Shimano will later disable the road shifters. Hopefully someone will give it a try.
