I’m hoping some folks might find it useful to know what bikes fit and won’t fit on the Tacx Neo 3M. Garmin publishes a list of incompatable bikes here:
I saw the QR PRsix on the list, and got a bit anxious as to whether my V-PR would fit, as the chain stay designs look similar. Thankfully (for me) it does fit, and in fact, it has tons of clearance between the trainer and chain stays. By extension, the X-PR should fit fine too.
If you have a Neo 3M and your tri-bike or aero bike fits, post in the negative or affirmative below, and maybe help someone out on a purchase decision.
