I just bought the cheapest CAAD9 frame I could (Tiagra model on sale) with the intent to customize and build as i wanted it so it came with an English BB. I just know that Cannondale ships frames with adapters so I assumed that was the case here after seeing "BB30" on the downtube. I'm awaiting a reply from Cannondale because the main reason i went with another CAAD9 was the option of BB30. I know it looks dirty but I only bought the thing just over a week ago.
