It's BB30 but with a 73mm shell rather than 68mm.
To make it work they made a new hollowgram spindle that's 109mm. I think the profile of the new hollowgram crank arms has been tweaked slightly so that the q is the same as the old arms with the 104mm spindle.
If your rotors are 30mm you don't need a new BB but you will need spacers on either side of the spindle. A quick Google indicates 5.5mm on the non drive side and 11mm on the drive side.
I have two spare 104mm axles, has anyone tried using one on a CAAD12? Disaster results?
