I have a endurance cf sl 7 and the seat post creak was horrendous, non stop. The problem with mine was at the top where the seat post goes in. There looks to be some plastic sleeve to stop any movement up top since the clamp is lower on the seat tube. The plastic sleeve on my bike was wearing down on the back.
I’m sure you guys have know idea wtf I’m talking about already so I’ll just keep it simple. Get this goop stuff and put a thin layer on the inside of the seat tube let it fully cure, thank me later.
