Still can pedal down hills, which might not be possible at 0%. I mostly didn't want to have to buy lower gears though. My kickr came with a 28 tooth cassette, and on steep hills that just wasn't enough. You could fiddle with that setting as a trial, and when it shows there is nothing wrong with your trainer, set it back.
