more ultegra front derailleur issues
Have you removed all the slack from the shifter cable? In my setup, I have in-line adjusters as the cables exit the shifters. If you have the same, turn them to effectively lengthen the housing and that will remove slack.
Thanks, I tightened the in-line barrel adjuster all the way and that helped. Now, however, I'm having another problem. When shifting the front derailleur, sometimes it overshifts to the outer and inner chain rings (causing the chain to come off) and sometimes it undershifts. I believe I have corrected the overshifting by tightening both stop screws but I don't understand what would cause under shifting (e.g., it shifts successfully but the chain rubs against the inner side of the derailleur when the chain is on the outer chain ring or against the outer side of the derailleur when the chain is on the inner chain ring). If I shift it back and forth between the two chain rings, eventually it'll shift into the proper position- but what a pain. Any ideas?
