BB30 was always a solution in search of a problem. But the solution to press fit bottom bracket creak is a threaded bottom bracket.
I have a BB30 bike, and did all the work with loctite and curing to stop the creak. While I did get it stopped, I’ll never buy BB30 again; a modern system shouldn’t force me to do all that nonsense.
Especially not when 68mm English threaded HT2 bottom brackets are so elegantly simple and work so well.
