MTB front and rear shimano derailleur: which shifters for drop bars?
I think it's silly and you should get a touring bike. However, if you run Dura Ace with those derailleurs, the front derailleur will work like normal. For the rear derailleur, you'll have to give a little slack and instead of pulling it straight out to pinch, you have to bend the line to a 90 degree angle and then pinch.
