Kickr Offset Value Changes

Recently my 2014 (edit - had the wrong model in here) Kickr had a massive shift in the offset value that is reported from a spindown. For years it’s been reported somewhere between 460 and 475 (maybe 480?). Last week all of the sudden it’s reporting 37269 - and it never changes. I’ve done at least a dozen spindowns and it always reports that number back - which is very unusual.

I contacted Wahoo support and was told that the offset number is irrelevant - that the app had updated and Wahoo had shifted from a strain gauge calculation to a computer power model. Here’s the quote from their support:

“This in no way indicates a problem or overheating of the unit. When KICKR moved from a strain gauge to a computer power model, the offset value became irrelevant.”

So now I can’t tell if my Kickr is acting weird or if I’m just hallucinating that it is because of this new value coming back. It does seem to be acting really wonky when I’m using power match and my Stages meter. (In erg mode the resistance won’t go up to the prescribed value for the interval - it just sits like 20 watts low.) If I run it without power match it seems to be fine - but I’m stuck with the 20 watt discrepancy between my Stages and the Kickr.


If anyone’s got any input or advice I’m all ears.

Ah, I see. I bought it in 2016 but it is indeed a 2014 model (WF104).

I don’t think it matters how accurate it is in absolute power, just that its consistent. Of course thats different if you’re trying to get powermatch to work with an external PM. Time and again I’ve come back to just realizing that its just a number, and as along as the numbers are consistent within themselves, (i.e. one unit) it doesn’t matter any more than any other number.

yeah I see what youre saying. Mine (V2 2016) is consistent, but doesnt match my Stages even when they are both freshly calibrated. I just dont use the stages on the trainer at all.

I always think I’m superman. The power meter tells me Im more like Luthor. Gene Hackman 1978 Luthor :pensive: :neutral_face:
