Di2 Front Mech problem
Installed Dura Ace 9070 di2 front mech on a Pinarello Graal.
Rear mech is fine, everything is good. Front mech however rubs in the 25 on the small ring and the next 3 gears on the cassette also. In the big ring it rubs in the 25 and the next 2.
I have followed the shimano workshop manual, I have successfully installed other groups on other bikes... but this one has me beat. Whatever I do I just cannot get it to not rub the front mech in the 25 ...... I have backed out to limit screws till they were barely in there, and I have played around with the micro adjust for the auto trim also. No dice...
Mech doesn't look exactly parallel to the top of the chainring to me either.. Mech hanger seems to be in good shape though.
Any ideas ?
