JetBlack VOLT strange sound

I bought the JetBlack volt and used it a couple of time with no issues. Then today it start making cracking noise from those wheels like something is a scratching.

Does anybody have any ideas? I already wrote to the store asking for a replacement since it has one year warranty, but I’d like to figure out what might have happened

Look in the Zwift Shop section which covers the Zwift Hub.

They are essentially the same.

You will see numerous threads covering the various noises the hub makes.
