CORE noise or vibration

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 [CORE] article.

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 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

If the cassette/Zwift Cog is secure...

5. When/where does the noise/vibration occur?

When pedaling AND coasting

Only when pedaling

Does it occur when you ride outside?

Yes, when I ride outside.

  • 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.
