Is it BB30 or PF30? Bearings might survive if BB30 direct to frame but no guarantees, if it's PF30 you'll probably fuck up the plastic shell bit.
Alu shell, so BB30. Also, see it has BB30 written on the Cannondale BB so it's not the Spesh one, that's for sure. I probably got a BB with the 'dale cranks and installed that.
