The negative slope setting affects the amount of physical grade simulated by Kickr Climb, Neo or other devices capable of simulating negative slopes.

If the ZERO setting is selected and the gradient changes to a negative number, your simulator will stay at 0% even when riding a negative gradient.

On the HALF setting, the grade simulator will only simulate half of the negative grade, for example riding on -10% gradient will be simulated as -5%.

On the FULL setting, the actual negative grade you are riding will be simulated.
