I might have read someone advise somewhere that you should use some loctite threadlocker to prevent loosening of the assembly. Is there a commonly accepted wisdom on this issue?
I've owned many Italian bikes since the late 70's and never once had a drive side cup come loose that was installed with grease and tightened correctly.
I have also worked on a lot of bikes that somebody used Loctite on the BB threads and it's always a disaster when it comes time to remove the BB.
I think "pedal rotation loosening" is more myth than fact.
