I have just bought a brand new Wahoo Kickr core. I previously a tacx Bushido (wheel on).
The core is much quieter, but there is some vibration, and I’m just not sure if it’s normal.
At low power, the only sound is the drive train, but once power gets above about 180w, there is a vibration felt through the whole bike with each pedal stroke, and a rhythmic deep sound with each pedal stroke. This isn’t related to flywheel speed and isn’t present when freewheeling.
I just wondered what others experience with the Kickr core is like. Is this sound and vibration normal? It’s fairly subtle, but I’m concerned this could develop into something else.
Here’s a link to a video of the sound:
I have tried:
- a different bike
- new cassette
- new chain
- re-indexing the gears
All of which have made zero difference. I know there were issues with early production units but these seem to have been different to the sound and vibration I am experiencing.
I’m planning on returning it to the store, but I suspect as the issue is pretty subtle they will tell me it’s normal.
