well, believe me, i'm trying to do whatever i can to buy as few new parts as possible. I'm running it right now with a nine speed Dura Ace BB and Cranks and a 10 speed Triple Front Derailer. It shifts, but it doesn't work too well. Sheldon Brown's website has a litle blurb somewhere about some triple FD's not working with double set ups, so between that and the non compatible cranks, i'm hoping to eliminate those problems.
i'm mostly concerned about having to replace the shifters as they cost an arm and a leg.
is anyone else out there running ultegra 10 triple shifters on a double system effectively?
