I cracked the plastic left BB cup on my Quickbeam a couple weeks ago trying to get rid of a creak. Yes, overtightening it. After 7 years of perfectly serviceable plastic cup life, so the service life seems acceptable to me. Yesterday I took the cup out, greased it up and put it back, crack and all. Creak appears gone.
