I’ve setup my 12 speed bike on my new Wahoo Kickr Move but have found gear changes are noisy and clunky.
I have a 12 speed 10-33 cassette on my bike and the same cassette on my Wahoo indoor trainer.
Any help and suggestions would be greatly welcome.
Shifting adjustment should be high on the list of things to try. How to do that depends on the drivetrain (I assume this is a SRAM bike and you put an XDR freehub on the trainer so you could fit that cassette). There is no guarantee that the cassette on the trainer is in the exact same position relative to the derailleur as it is on your rear wheel.
A certain amount of clunking noise is expected from shifts but not chattering of the chain.
You should also check chain wear since a worn chain will not run smooth on a new cassette. If that’s the issue, you would observe it goes away if you put the cassette from the bike onto the trainer, but the proper fix would be chain replacement.
