Help - can't identify bottom bracket replacement Cannondale Bad Boy eccentric BB

Hi I need some help to identify a replacement bottom bracket replacement for my Cannondale Bad Boy (Lefty).

I THINK the bike is a 2009 or 2010 "Disc" model (?) it came with a 3 speed iMotion SRAM hub gear (I have since changed the a single speed).

I'd like to replace both the bottom bracket unit as well as the eccentric BSA adaptor (or the whole thing if it is a single unit). The diameter is circa 58mm and the width is 68mm. On the side the BB has "BSA 43-09", some torgue info and "C10 Mk4".

Attached are pictures - if someone could identify the BB and / or the specific Bad Boy model I would be very very grateful!!!

Many thanks
