BB size for a 56cm Specialized Transition

I have ordered the 2006 Specialized Transition and can not figure out what size BB it takes. I have set of FSA cranks that I will be using. So far all I have is 68 mm, but need the spindle length to follow the correct chainline. I have called my LBS and emailed Specialized, but no answers yet. Thanks for any info.

Spindle length is set by the crank you use. Check the FSA homepage.

Thanks! Got it 68mm x 108mm.
