My road bike (2012 Specialized S-Works Venge) has a creaky bottom bracket that I'd like to replace. I can't figure out what bottom bracket it currently has though!
When I had the cranks installed originally, the specialized dealer used epoxy to put the aluminum cups into the frame. I looked it up and this procedure is typical for specialized road bikes of this year.
The bottom bracket couldn't take a Shimano crankset so they used adapters (see pictures below, black "spacers" that taper by the crank arms). Everything worked well with this configuration, but now that I want to replace the bottom bracket I'm unsure of what to get.
I went to a different specialized dealer and asked what I needed and the mechanic took a quick look and said "You have shimano adapters on there. Just get another PF30 bottom bracket and you're good". I'm questioning the PF30 comment because he didn't seem very sure of himself when he responded. I also read online that specialized bikes of this year have a "Specialized OSBB" bottom bracket.

Now I'm super confused. Which bottom bracket do I need to buy? Can I just reuse the metal adapters?
Thanks for any insight.
