Hey @Kav75 ,
I have looked through several spec sheets and have not found that the Trail SL4 has a thru axle. Do you mind posting a picture so we have a better idea of which thru axle it uses? If it is a standard quick release then you are good to go.
That being said the adapters that come with the Tacx neo fit all common thru axles and should cover yours without complaint.
Looking forward to seeing what you have,
