I have a strange creaking noise coming from my bike. It's sounds like its coming from right underneath me (bottom bracket/linkage area). It's mostly going down hill on rough stuff or really cranking it. Disappears if I am going downhill just sat down with feet off the pedals though.
I had my bearing replaced earlier in the year and there's no play at all so don't think it's that. Thought it could be the bottom bracket but replaced that this morning and its still making the noise!
What could it be, thoughts please!!
