Today I installed my new Kickr Core. It is working fine, except for one thing:
The cadence displayed in the Sufferfest app is showing very strange fluctuations.
I am pedalling steadily at 90 RPM, then suddenly the cadence displayed goes from 90 to 120 RPM, while I am still pedalling at the same cadence… after a while it is suddenly showing 90 RPM again, then later it switches back to 120, etc… The changes occur every 10-20 seconds or so.
Does anybody have an idea what could be going on here? And what I could do about this?
