I've got the itch to get another bike and noticed that a few of my choices(Cannondale CAADX & Diamondback Steilacoom RCX) come with a BB30. I tried doing a search in the clydesdale forum and did not come up with anything. The results from the rest of the forums seem to be mixed. Some reviews indicate that the BB30 will develop a creaking sound. Am I worrying too much?
