Cadence decreasing periodically

Cadence is dropping intermittently during rides to ~40 RPM? Noticed over the last few weeks - recovers but cadence will be relatively static during time that drops are observed. Any similar symptoms been observed?

Typically run via Apple iPad
Kickr core v1.0.13

Easy, keep pedalling at same cadence.

Alternatively, use zwiftalizer.com to check dropouts. As probably your cadence sensor has connection drops.

I think that the Core uses a calculation based on changes in power at different points of the pedal stroke to determine the cadence (i.e. there is no actual cadence sensor). So, it’s possible that at those points where the cadence shows to drop that you just happen to be pedaling with a very smooth power level through the entire pedal stroke, thus ‘confusing’ the algorithm.

It could be dropouts, too, of course, but we can’t see if your power is going the same thing in the screenshots you posted.

Will check out the log analysis, but I don’t see a significant correlation between power and cadence. Eg:

This analysis doesn’t look like it identified anything?

That looks perfect indeed.
