Cannondale CAAD12 bottom bracket choices

Hi, I have just bought a new Cannondale CAAD12 frameset, and am sooo confused about the stupid bottom bracket. My questions and confusiuon are born out of the following: I have Dura Ace 9000 groupset and dont want to buy cannondales own sisl cranks so, The frame was supplied with 2 bottom bracket bearings, do i just loctite 609 these into the bb shell? if so do i need to buy any further shims/reducers etc so the cranks fit properly? If not, the CAAD12 frame has BB30 written underneath, so do i buy a BB30 bracket, and if so do i need to buy any shims/reducers so the cranks fit properly? I read the CAAD12 needs BB30A, so why wouldnt the frame say BB30A instead of just BB30? If not, do I buy a BB30A bracket from Cbear or Wheels manufacturing, if the wheels one which one as theres a few BB30A for shimano? I have also seen the Wheels spacer kit which looks like it has some cups and spacers, i dont get why they would sell the spacer kit if you can just buy the whole BB from them. Do you buy these if you have a standard BB30 or to add to the bearings i was supplied with. Have also read FSA do some green 24mm reducers that may work. Far too many conflicting stories around, so trying to get some good info as i fancy sending the frame back and buying a more standarised frame that all of my components fit. have attached links to show the varuing costs and options thanks https://www.sigmasports.com/item/C-Bear/BB30A-Cannondale-Bottom-Bracket/EVWS?co=GBR&cu=GBP&glCountry=GB&id=694540&gclid=Cj0KCQjwyoHlBRCNARIsAFjKJ6AeUP54Kn0LPpghcWupNjr0afT_5J08o9DBfKwWNNJwrl0tnJ0osuwaAqjcEALw_wcB&gclsrc=aw.ds https://www.sigmasports.com/item/Wheels-Manufacturing/BB30-to-24mm-Adapter/S1U https://www.sigmasports.com/item/Wheels-Manufacturing/BB30A-to-Outboard-Bottom-Bracket-for-24mm-Cranks/KZ7X

Hi,

I have just bought a new Cannondale CAAD12 frameset, and am sooo confused about the stupid bottom bracket.

My questions and confusiuon are born out of the following:

I have Dura Ace 9000 groupset and dont want to buy cannondales own sisl cranks so,

The frame was supplied with 2 bottom bracket bearings, do i just loctite 609 these into the bb shell? if so do i need to buy any further shims/reducers etc so the cranks fit properly?

If not, the CAAD12 frame has BB30 written underneath, so do i buy a BB30 bracket, and if so do i need to buy any shims/reducers so the cranks fit properly? I read the CAAD12 needs BB30A, so why wouldnt the frame say BB30A instead of just BB30?

If not, do I buy a BB30A bracket from Cbear or Wheels manufacturing, if the wheels one which one as theres a few BB30A for shimano? I have also seen the Wheels spacer kit which looks like it has some cups and spacers, i dont get why they would sell the spacer kit if you can just buy the whole BB from them. Do you buy these if you have a standard BB30 or to add to the bearings i was supplied with. Have also read FSA do some green 24mm reducers that may work.
