Tacx Flow Smart + Zwift = horrible noise (not the rider)

[Thisonepotato]

Happy New Year to all.

I have recently upgraded to a Tacx Flow Smart for my garage Zwift sessions.

Today was my second ride and yet again a horrible noise. Set up is a Specialised Allez on the Tacx Flow Smart with Zwift on an old Ipad Mini 2. I ensured that the TT was calibrated before both rides and the Tacx App said it was.

The TT is paired up ok however periodically and usually when the ride goes to a negative gradient something is making a hell of a noise. Sounds almost like the noise I hear on more expensive bikes coasting, the noise usually stops when the gradient gets back to 0 or above.

I have recorded the noise on video but cannot seem to upload with sound. Thumbsnap seems to steal the sound but someone elses trainer that I have found https://vimeo.com/462315264. Mine sounds like this but at times it is almost silent.

Hi are you running a trainer tyre ? The blue one pressure is usually around 90psi setting the contact pressure.

Had a Flow Smart a couple of years ago and the metal sleeve on the roller can get loose and your hear a clicking noise when the tyre presses on that point.

Mine was replaced under warranty but then the replacement started making the same noise eventually.

Thanks just running normal tire.

I am RMA'ing it to Garmin.

Thanks all
