X, Kickr and Resistance

I have had the Kickr for 3 seasons now, but I am a newbie to X. There is something I am trying to understand. I have done the 4DP test in X to establish my numbers. But when I go to do a ride, I feel like the resistance doesn’t track with the grade. Today I was going up an 8% grade and felt like I was on the verge of spinning out. I left ERG mode and would select different levels to get a workout. This doesn’t seem right. What am I missing?

Hey @scottskaja, welcome to the forums!

When you say you were “going up an 8% grade”, do you mean, in a SYSTM workout? Cuz if that’s the case, those grades are only there to send a signal to the Kickr Bike or Climb to raise the front end (and or lower it, depending on what is shown).

WahooX (eg. SYSTM) is not a sim like Zwift, indieVelo, FulGaz, Rouvy etc so if a SYSTM workout is displaying a gradient, it won’t necessarily feel like that gradient. It’s really more there to make the content more engaging for those that have the extra hardware.
