FSA BB-4000 MegaExo 19 bottom bracket review

My 2014 Specialized AWOL came with an FSA Omega MegaExo 19 triple crank and an FSA BB-4000 bottom bracket.  I bought the bike in October and in March I started thinking about doing some post-winter maintenance.   One of the things that I wanted to do was remove and examine the bottom bracket.  Since I was not familiar with outboard bearing bottom brackets, I did some research about the BB-4000 bottom bracket, and here is what I found out.

Mystery of the Specialized “RCC” hub bearings, or Specialized Twitter support confusion

I could not decipher what was written about the wheel hubs in the official spec sheet for the Specialized AWOL.  For both front and rear hubs, the specs say:

Specialized Hi Lo disc, alloy, RCC bearing system, QR, 32h

What exactly is RCC bearing system?  I could not find anything related to this term anywhere.  So I figured I’d ask Specialized through their dedicated Twitter support account.  The dialogue that ensued was quite comic.
