Noise or vibration can come from a number of places.
Noise or vibration can come from a number of places, and frequently is a compatibility, setup, or installation issue. Confirming the following in order is the quickest and best way to identify and, hopefully, resolve the noise / sensation.
1. Frame compatibility
The first step in resolving noise is confirming that your bicycle frame is, in fact, compatible with the CORE. The principles and details of frame compatibility are laid out in our Bicycle Frame Compatibility [KICKR] OR Bicycle Frame Compatibility [KICKR MOVE] articles.
2. Drivetrain compatibility
The next step is confirming that the cassette or Zwift Cog installed on the CORE are compatible with the drivetrain installed on your bike. An explanation of drivetrain compatibility can be found in the Drivetrain Compatibility for KICKR, CORE, and MOVE trainers article.
3. Setup / Adapter Installation
Please review the trainer adapter installation relevant to your bike in the KICKR Trainer adapter installation article and confirm that the correct adapters are being used and are correctly rotated.
- Quick release 130 mm
- Quick release 135 mm
- Thru axle 142 mm
- Thru axle 148 mm
If you are unsure of the proper width value, take a ruler and measure from the inside edge of your bike frame rear dropouts (where the wheel is inserted into the frame) to the other.
4. Cassette / Zwift Cog installation
The next thing to confirm is that the cassette is installed squarely and without play. It's best to remove your bike for this step.
With the bike removed, facing the cassette from the side of the trainer, place your hands on the larger cogs of the cassette and try to pull them toward you and push them away.
If the cassette or Zwift Cog is loose see articles below AND
- Between removing and reinstalling the cassette or Zwift Cog, we would also suggest confirming that the freehub body locknut (14mm or 17mm) is snug + 1/8 turn. If not, snug it + 1/8 and confirm the freehub body doesn't move toward you when you pull on it.

If you're experiencing the vibration or noise whenever you ride the bike, we can exclude the trainer as the cause, which means it is time to get a second opinion from a bike friend or your local bike shop about what the noise is, and if is something that needs to be addressed with your bike.
No, only on the trainer.
Please see Drivetrain indexing adjustment and wear.
