I’m hoping one of you experts might be able to help me.

I have just recently purchased a Trek Domane AL2 2025 bike and I would like to attach it to my turbo trainer in the evenings. The turbo is a Garmin Tacx Flow smart trainer (second hand).

I’m relatively useless when it comes to knowing anything about bikes, but I’ve gathered so far that I need a thru axle to be able to connect my bike to it.

Would any of you be able to advise on what thru axle I need, is it a 12x142mm one, is it a tapered one?

thanks in advance …!

The alternative is that I buy a wahoo kickr turbo or one where I take the wheel off but theyre all a bit out of my price range at the minute.
