Trek Y-Foil Front Derailleur
I recently picked up a Y-Foil frame set off Craigslist and had my LBS inspect the integrity of the frame. It got a clean bill of a health and looks to be in excellent shape, given the fact that it's from 1998. It was definitely ridden but it was not put away wet.
Ironically I had the same bike (gold) back in the early 2000s but sold it, so I was pretty excited about picking up what appears to be an excellent project bike.
I know zip about building bikes but I picked up a few books, some tools and was going to give it a shop through my local bike collective (http://davisbikecollective.org
Ideally I'd like to find a 7700 Dura Ace 9-speed group to keep everything original but someone (local to me) is selling a full Ultegra 6800 group from a take off project for $550 and it seems too good to pass up.
Am I going to run into compatibility issues with such a new group set on an older, unique frame?
Thanks for dealing with my n00bish question(s).
