It has a Specialized OSBB bottom bracket. How do I know this? I've seen one in person. The Shimano crank fits it because they put in spacers, like those made by WheelsMfg, not sure why Specialized don't list the BB on their page.
EDIT: Although reading the specs page, I see they say "Threaded BB". Maybe I'm wrong here... I'll check out the guy's bike tonight on our group ride, but I'm 99% sure it has installed spacers on it. Regardless, the fact remains many bikes come with these spacers installed. Here's another example:
