Tacx QR adapter set for TA not working on my Specialized tarmac.

Hi,

I have a Tarmac SL6 comp 2019 with Thru-Axel and disc brakes. I wanted to use it on my Tacx Neo.  I Purchased the Tacx QR adapter adapter set for 142mm TA.

First i had the problem to get nut from the adapter set on the drive side into my Specialized frame.. This turned out to be a specialized problem.

When I fixed that and had set up the Tacx neo correctly with the adopter kit and mounted the bike i noticed that there is still a lot of play/movement between the frame/adapter( QR bolt) on the non drive side. I am using the right parts of the adapter set, but it feels like the frame and the coned nut on the QR bolt is not fitting well..

Do any others have a similar problem?

How did you fix it?

Thanks for any help
