Not in my experience. I've had and seen numerous UN72/73 bottom brackets in service for well over 30,000 miles and still be in good condition when they were replaced as part of a crank upgrade. Shimano sealed cartridge bottom brackets are one of bicycling's real bargains for both cost and durability.
How can something nobody ever sees be sexy?
