I started a winter project a couiple of years ago. I converted a Trek 930 mtb bike to a drop bar winter bike, using a triple crank, tiagra triple FD, and Shifters, (9 speed). To get the road FD to work, I drilled a small hole underneath the BB shell, attached a cable guide. Front shifting was perfect (50/39/30). It took a few trys to find the correct length bottom bracket with the Sugino AT crank, but after that, shifiing was excellent
