Di2 Front Mech Adjustment

jonbob78

I currently have Ultegra Di2 6870 and whilst the shifting from front small to big works perfectly there is a little chain rub when riding on the big ring. It still micro adjusts when moving up and down the cassette.

Should Di2 be automatically set up based on limit screws or is there a way of shifting the mech a fraction to the right to stop the rub.

Searched the web and YouTube without much success

Thanks

might be the angle of the front mech - try rotating it a little

Set it up exactly as per the installation instructions for angle, distance from big ring and limit screws, and it'll work correctly.

That's a good link. What he seems to be suggesting is to set it up exactly as per the installation instructions for angle, distance from big ring and limit screws, and it'll work correctly.
