I made a feature request quite some time ago to make “Tacx NEO road feel” a slider (similar to trainer difficulty) instead of a simple “ON/OFF”.
The NEO line supports this functionality. (see above-linked thread, or go into the TACX training app where it’s demoable)
I’ve disabled it entirely as Zwift makes cobblestones feel like potholes.
I ride a ~38mm tires at low pressure in the real world - I’d like to match that feel to my NEO in Zwift.
