Was this just a bad run or do they all creak?? I Just installed new 52/36 DA 9100 cranks, DA chain and DA 9100 12-28 cassette. It's my 2nd 9100 cassette. The first had basically zero creaking..occasionally if I was in the 36 in front and got into the 28 n rear, I would get a creak but only for one or two pedal strokes then it would go away. No big deal. BUT with this setup when I am in my 52 and 25/23/19/17 under heavy load or out of the saddle, I get this horrendous creaking. I replaced the cassette with another and I am getting the same creaks. Cassette is torqued to 40nM (even past by a few clicks), shifting is perfect, no chain rub or loud drivetrain. I am not a ******. 5'11" and 160 lbs, so not due to being 250. I know the 28/25 and 23/21/19 have the carbon shell/rivots design which seems to be what is causing the noise.

Any clues/advice is greatly appreciate.d My LBS and many other sources are stumped. Shimano knows nothing about this of course...
