All 2014 Cannondale SuperSix EVO's have a PF30 bottom bracket shell which requires a PF30 Bottom Bracket. The frame has a BB30 logo on it even thou its PF30, Cannondale has done this for years. They call it a PressFit BB30 which has lead to the confusion. On your frame the BB30 bearings are in cups that are pressed into the frame where as the BB30 shell frames have the BB30 bearings pressed DIRECTLY into the frame, using circlip snap rings.
