Hi, I was reinstalling the back derailleur (shimano ultegra di2 11 speed) on my bike and for some reason can’t get rid of the sag.
It’s causing me chain to have no tension and only the middle speeds pass.
Would you guys know how I can fix my problem ? Thanks a lot

Make sure the part of the derailleur that screws into the hanger is positioned correctly. There will be a pivoting piece with a notch that needs to engage the notch on the hanger. If you have it on correctly and still have this issue, you either have too many links or your b limit is off
It’s not installed correctly. The part that actually screws into the hanger needs to be essentially horizontal. There’s a tab on it that needs to rest on hanger where a b-tension screw would normally rest.
