I have a Giant road bike with Shimano Ultegra gears.

The outer side of the front derailleur is making contact with the chain, on both drive sprockets, when in the highest gear at the rear.

I have fiddled with both high an low adjustment screws but cannot get the derailleur to move enough to stop contact.

The derailleur is parallel to the crank.

Would anyone have any ideas?
