Sealed BBs don't last forever. They seem to last about as long as loose ball BBs, but with less maintenance along the way.

Square-taper sealed cartridge BBs do flex substantially more than traditional cup-and-cone BBs, because the spindle overhangs the bearings by a longer distance. The first time I saw cartridge BBs was in the new fleet of rental bikes at the shop where I worked in 1992. The first test ride I did after building one up made me think something was broken, because the pedals dove so far underneath the BB shell.


So now you're going to impart real knowledge? That isn't like you.
