Biopace chain rings causing fluctuations in power readings ?

Postby ErikD » Wed Oct 24, 2018 10:02 am

I have recently bought a Directo and have started using with both MyEtraining and Zwift.
On both platforms I notice that approx. every 3rd power measurement is significantly higher (10-30 w) than the other measurements, which I believe to be closer to the actual workload.
My bike is equipped with Biopace chain rings and I wonder if the oval shape could be causing these fluctuations in power measurements ?

This is quite interesting.
Please contact our customer care at myetraining@elite-it.com.
Do also a training at constant power and ride on it at constant speed and cadence. The issue should be visible.
Export the training and add it on your request.
