'brifter' is f'ing stupid
You heard wrong. If anything having a magnet on a newer Quarq will make it worse. That comes directly from SRAM's road product manager.I have those Quarqs but I hear it's more accurate with the magnet. I'm also having an issue on one of my bikes with the Shimano shift plate for the front derailleur constantly falling off so I want to glue that as well.
ETA: The plate under the support screw? How can it fall off if the derailleur is installed correctly? Hint: There is only one correct answer.
