What up fam? I need some help with fitting a Rotor 3D+ crank on my 2007 Specialized Transition Pro.

I think I need external bearings for my shell that allow me to use a 30mm spindle which the Rotor 3D+ has.
I want to order the right bearings but dont know what shell my bike has. I do know what bearings and crank I have now.
So I hope someone can help me figure out from those, what shell i have.

From there I would be able to look for a bearing cartridge that fits my shell and allows 30mm spindle cranks like the Rotor 3D+.
This is what I know now:


Frame : 2007 Specialized Transition Pro
(http://www.specialized.com/.../transitionpro#specs) I bought it frame only.


Current Bearings : sm-bb6700 bc1,37 x 24 Road
(http://www.ciclismoshop.com/en/bottom-brackets/617-shimano-ultegra-sm-bb6700-bottom-bracket-cups-bc137-x-24-bsc-bsa.html)


Current Crank : FSA SLK carbon Crank

Rotor Crank : Rotor 3D+ 130 BCD MAS
(http://www.bike24.com/p266329.html)
This is a compatibility chart they added: http://www.bike24.com/data/25974.pdf


I have read about bikes with a BB30 bottom bracket, that want to fit a 24 mm spindle, and that they have an adapter for that.
I need kind of the opposite of that I think. I need to fit a 30mm spindle on a non-BB30 frame. I think I have BSA 68 shell, but am not sure.


Thanks in advance for any help. - Daniel
