I just purchased a Tacx Flux S direct drive trainer and currently have my road bike setup on it and have really enjoyed it. I have been using a wheel on Kinetic trainer for years and this feels much nicer and am enjoying ERG mode.
I want to set my mountain bike up on the trainer just to change things up a bit and see how it feels. Is it necessary to change out the cassette that I have on the trainer (Shimano 11-28)? Since I’m using ERG mode does it not matter or will the Sram GX eagle derailleur not work with the Shimano 11-28 cassette? Not a big deal to throw the eagle cassette on but just swapping bikes is easiest.
This wouldn’t be my constant setup but more for fun and to mix things up for a minute.
