Wahoo Climb while in ERG mode


(Selino Valdes) #1

Would it be possible to send the gradient data to the smart trainer while maintaining ERG resistance? Currently I cannot have a working Wahoo Climb while in an ERG workout. The trainer does not send the data to the Climb. Does that mean that it’s not getting any from Zwift or something else? :man_shrugging:t4:

Hey Selino, the Climb reacts to the resistance change in those modes based on gradient or environment. The Climb simulates environmental obstacles. ERG mode resistance change is based on watts and cadence so there’s no real world “simulation” really.

It would be really nice if in ERG the kickr climb followed Zwift elevation, while allowing us to do structured power based workouts.

Agree. It would be nice for the climb to react in ERG mode if nothing else to move your weight and sitz bones around in the saddle.

+1 I would really appreciate if gradient data were included in workout/ERG mode for Wahoo Kickr/Climb, regardless of the fixed resistance in ERG.

I think “Terrain” should be a third option during workouts (in addition to ERG and Incline) on the companion app whereby the slope data is sent and changes the resistance (and Climb slope) like a free ride. Even if you don’t have a Climb this is a useful setting because it replicates doing a workout outside.

@Chip_Brunk: how would that work. what if your workout call for a 2 min vo2 max effort (400w) but you are going down a hill, you wont have enough resistance on your wheel to produce that kind of power.

Check out my feature request for more on this https://forums.zwift.com/t/add-terrain-mode-option-to-workouts-especially-great-for-kickr-climb/14694?u=chip_brunk but I’d do my hard intervals when climbng just like I do structured workouts outdoors. Between the Workout “Pause” button and the ability to turn around with the arrow key/button it would be pretty easy to control but does require you know a little about the course you are riding.

I do not understand. Why can’t the Kickr adjust the resistance while the Climb changes the grade?


(Edoardo Dellepiane) #10

Good question and I’d like to understand too. Anybody knows that?


(Selino Valdes) #11

Gradient is sent to the wahoo kickr and the trainer calculates the resistance using that number. The kickr then sends the gradient to the Climb. So there’s just a single number being sent. If you change that number with ERG then it’s also changed for the Climb. There’s no way for the Kickr to know that the gradient is 8% if the resistance is set to 250w because it’s using one method for both. The method of sending the resistance and the gradient would have to be refactored for this feature request to be fulfilled.
