It’s been mention in other threads, but I’m hoping to start a tread specific to the noise people are experiencing with the Force Cassette, and solution that have made the problem better.
I just upgraded from a wheel on trainer to a direct drive Saris H3. This means that it is super quite, and the only thing I hear/feel is the drivetrain now. For reference my chain has ~1000 miles, and the cassette is brand new
The noise starts as soon as you get to the smallest three cogs in the rear. Even with zero power going through the pedals, you can hear and feel the chain running through the cassette and or jockey wheels. When applying power it become unbearably loud, and I can even feel the vibration in my feet. As soon as I free wheel the sound disappears. Suggesting there is nothing wrong with the trainer or freehub.
At this point I’m almost tempted to go back to my wheel on trainer and listen to wheel noise.
Here is another example pulled from the 12 speed waxing chain forum post, with the same issue it sounds like.
