So I installed a set of Race Face Cadence cranks in place of my old Ultegra (non external) and it started creaking. I have changed, tightened and greased other things, so it pretty much has to be the BB. I have tried grease, lots of grease, reinstallation after cleaning, teflon tape and loctite- none seems to work much better than another. I am almost positive the frame was faced and chased before I got it, but that was several years ago. Is the next step taking it for facing to see if that fixes it? Any other ideas?
