There are various camps out there on the internet that swear by threaded bottom brackets as a means to avoid creaking. This video below shows the pro’s and con’s of both.
If you are about to buy a Cervelo bike, watch this video. It shows the appalling tolerances the bike frames are made to. The bottom bracket pressfit specification is so bad, neither NTN or SKF will warranty their bearings in it. This particular frame had misalignment between the two halves of the frame body.
Paul Green of Paul Green Vlogs got in touch about some problems he’d been having on his Trek Checkpoint bike. He had gone through bottom brackets at quite an alarming rate. Almost four bottom brackets from different manufacturers had become unserviceable in a relatively short time. The failed bottom brackets consisted of a few Shimano OE units and most recently a Thread Together type BB from Wheels Manufacturing. The bottom bracket type was BB86 and the frame was made of aluminum.
This article is a technical discussion of the pros and cons of using grease or retaining compound for installation of bearings and bottom brackets. A general trend in recent times has been a move towards slacker fits. This improves performance and service life.
