Hi community, is it normal that the speed is dropping like this ? I already read in a “wahoo help post” that it can be caused by bluetooth/wifi interferences. Im far away from any router or pc. I only use the ipad next to the bike. Would be great if anybody can give me a hint whats going on. Kickr core was set to ERG.

R u using virtual speed? If not, give that a shot and you might find the speed report is more accurate and doesn’t show dropouts. Edit: where are my manners? Welcome to the forums @bacardipur!! ---

Hi, funny thing. I never experienced something like this in systm. Your speed seems to be reduced every 31 Seconds. But I have a similar thing most of the times in Strava from my SYSTM rides with virtual speed. Strava with oscillating/reduced speed about every 23s seconds: ![image](https://us1.discourse-cdn.com/flex020/uploads/thesufferfest/original/2X/3/374852fd55f48904963f26d3890b927268120788.png) SYSTM speed looks OK, but it might be smoothed: ![image](https://us1.discourse-cdn.com/flex020/uploads/thesufferfest/original/2X/4/4f4cd267db25562e7ca657229466f415290a4ca9.png) ---

@Thomas Im syncing to garmin i just a looked at the speed over there. The graph seems to be the same. In general i have no big problem if the graph is not smooth but i sometimes have low frequency vibrations and want to exclude that the force control loop of the wahoo kickr is not ok. Next time i drive, i take a stopwatch and see if the vibrations happen in a oscillating manner. ![GarminKickrCore_2022-11-03 22_16_32-Garmin Connect - Brave](https://us1.discourse-cdn.com/flex020/uploads/thesufferfest/original/2X/4/4e29847b67074ccff3cfa15d079d670bb6b19915.png)
