My older tri bike had an annoying creak, seamingly from the bottom bracket area when pushing power, going up a climb, etc. Between myself and my LBS we spent hours trying to solve it. Eventually determined the noise wasn't from the bottom bracket (although you'd swear it was). Turned out to be the seat post (carbon seatpost in a carbon frame). Pulled it out, cleaned post and inside of frame and applied some carbon paste. No more noise.May check this on my SC seat post which also uses the BB90 bearings and is a creaker... I've used the green lock-tite on my BB bearings, greased the QRs, tightened bolts here and there... still have creaks.
I've thought about buying from these guys next time... their bearing kit contains a green lock-tite I believe as well.

Historically I buy my bearing from Wheels Manufacturing... I use the Angular bearings.
