I m looking at buying a Specialized Tarmac Disc 2018 frame only and move parts over from another bike. The Tarmac Disc comes with a OSBB, CeramicSpeed bearings Bottom Bracket, and I currently have a SRM THM Clavicula M3 crankset, and which says is compatible with both threaded BSA frames, as well as BB30, PF30, and BB86 PressFit options.

But as I know nothing about Bottom Brackets, I would like some input if I can even do this? Does the THM crankset work with a Specialized OSBB?

S-Works Tarmac SL6 OSBB is actually BB30: https://www.kogel.cc/blogs/kbba/special ... -explained

Yes your cranks are compatible. At worst you would need a spacer, but I don't even think you need that.
