Hi , I had a synapse with the same problem and did all kinds of research and even contacted loctite and came up with a loctite bearing mount compound 680 and 641 one was more permanent than the other but I was told knocking the bearing out when needed was not going to be a problem. I never did the job as my FD hanger screwed up and they warranted my frame and then I went to a EVO that has a press fit BB30 but I now also have a regular supersix with a BB30 but it's not making any noise , if it does someday I'll try grease then the bearing mount compound. Any compound left behind after knocking out the bearing can be removed with a solvent as the BB is aluminum. Press fit BB do not have aluminum inserts in their BB
