[Closed] Help - OSBB / PF30 EBB and many other abbreviations that befuddle me..

I was going to sell my 2014 Specializd Roubaix disc frame and forks, but realized that it is not worth a great deal, 25000 miles have left it a bit tired looking, and because i know i'd be scared to lock up it's shinier new replacement anywhere. I am thinking of keeping it but as i live in the Norfolk Alps, most of my bikes are singlespeed.

My thought was that as it OSSBB (Spec's own BB30/PF30 type standard) that i should be able to run the BB as an Eccentric one like this?

Anyone have an idea whether the PF30 adaptor will fit the OSBB of the carbon frame as in words of the prophet, Shaun Ryder, my melon is twisted!?
