Question, curious more than anything.

Would you trust a NOS sealed BB that sat on a shelf for the last 30 years? I honestly don't have a ton of experience with sealed stuff so I really don't know if the lubricant inside would hold up longer over time.

Specifically, one of the F.A.G. brand BBs, if you need technical details, see: http://www.schaeffler.com/remotemedi...14_5_de_en.pdf
