KICKR Core - Zwift Cog Engagement Issue – Loud "Bang" Noise and Delay

Hi everyone,
I’m having an issue with my new Wahoo KICKR Core + Zwift Cog and wanted to see if anyone has experienced something similar or has suggestions. When I backpedal and then start pedaling forward again, there’s a delay before the cassette engages. During this delay, the chain moves freely without pulling the cassette, and then when it finally engages, there’s a loud “bang” noise.

Here are the details:

  • The issue happens when I pedal backward and then resume forward pedaling.
  • There’s noticeable free movement (play) before the cassette catches, which is followed by a loud “bang.”
  • I’m using a Zwift-compatible cassette on the KICKR Core.

Has anyone dealt with this issue before, or have any advice on what could be causing it? Any troubleshooting tips or solutions would be greatly appreciated! This unit came with the Zwift Ride recently, so I assume it’s still under warranty.

Thanks in advance!

Hi,

I seem to have the same issue. For me it also occurs when the resistance is reduced, so it makes Zwift really hard to use.
Did you find a solution to this?

Thank you for your help in advance.

Hi All,

Welcome to the forums, @Stefan_S7.

This is Jose from Zwift.

Thank you for contacting us! To assist you better, we would greatly appreciate it if you could send us a 20-second video in MP4 format, demonstrating the problem. It would be helpful if someone could record you pedaling while keeping the camera steady and focused.

Please ensure that the video captures the cog or cassette, and the chain, and includes a close-up of the area where you believe the noise might be coming from.

You can send the video to: support@zwift.com.

We look forward to helping you!
