Zwift Ride sticking at 10 - 20 watts

Hello everyone. I just bought a Zwift setup with the Kickr Core. Everything is working fine, except that when I stop pedaling, my wattage lingers around 10-20 watts for about 5-10 seconds before it drops to zero, and my cadence briefly spikes to around 120 RPM. Has anyone experienced this issue or can offer some advice?

Hi @Marco_Manitta, welcome to the forums. I’m Gian from Zwift.

I’m sorry to hear that you’re having an issue with your Zwift Ride. We’re happy to take a look!

Please try doing a manual spindown calibration for the Wahoo trainer by following these steps. If the issue persists, could you please confirm if you’re able to reproduce the problem on the Wahoo app when doing a free ride? You won’t be able to shift using Wahoo’s app, but you can control the resistance manually.

If the above doesn’t seem to work, please reach out to us so we can give you one-on-one assistance.
