This morning after completing Geiger -5 as prescribed, I decided to tack on a few extra minutes in “standard” mode to get in a sprint or two. About 20 seconds into a 30 second effort around 500 W, I heard what I thought was my tire going flat. You know that dreaded “psst” sound. Just as I was getting to the end of the effort, the resistance dropped to basically zero. I started coasting and, to my surprise, the wheel just kept spinning. I manually slowed the wheel down and then I realized my tire was not flat at all, and the reason I had trouble stopping the wheel was due to the flywheel inertia. I noted the trainer was warm, but I don’t think any warmer than what I typically see after doing some longer, sustained efforts. (2x12 @ ~300 W in this case). I put the trainer back in erg mode and started spinning again, and it was struggling to hold 50 W (target power was 136 W at that point).
I had to hop off the trainer and get ready for work, so I wasn’t able to look into this more, but I’m afraid I just broke my trainer! Has anyone ever had a similar experience with their Wahoo Kickr Snap?
