As you can see, I can
brand is irrlevant, same as frame color and groupset, including thickness of handlebar tape. And explain please what pic of a bike will tell you about seatpost knocking INSIDE seat tube ??? I matter of technical aspects of bikes & co I am rarely wrong. Really rarely. However sometimes everyone has kind of blindness not seeing obvious, so it was my reason to ask on forum for possible source of my issue.
Nevermind, problem solved. I took a risk and cut seatpost ; total silence. As it should be from the beggining. As it always is on my bikes. No exception. Kind of obesssion
I can hear only wind and tires.
Now in 15cm seat tube sleeve I have 14 cm of seatpost. Another thing is its dimension inconsistency. Last 3 cm ( aboutish ) was fractionally thicker, I believe if it keep same size thru all length it wouldn't be a problem. Or maybe not.

I can be wrong, and have plenty of examples for that
