I recently put a new bike on my Wahoo KICKR (a Cervelo with thru axles; previous bike had QR skewers) and noticed that I’m getting a worrisome grinding noise and sensation under certain scenarios. This appears to happen when I’m either in the big chainring and pedaling <80rpm, or in the small chainring and pedaling at any cadence.
Here’s a video: https://youtu.be/wAJifuCSH4s Hopefully you can hear the grinding noise, although it’s a bit quiet in the video.
Have any of you guys experienced this before and have any idea what might be causing it?
For what it’s worth, I checked with Wahoo and they didn’t offer an explanation - they just want me to exchange the entire unit, which I’d rather not do due to environmental reasons if it’s a fix I can perform on my own end.
Thanks so much for any advice!
