148X12mm? Not really.

I've used it several times

Tacx, make a better 148X12mm axel for the Neo. The 142X12mm conversion is supposed to work for 148mm? Where is the 6mm spacer? The current solution creaks, groans, and moves too much. Over tightening the skewer causes the threads on the aluminum end cap to pull out.


I’m confused as to wether or not this is the right adaptor to fit my 12X142 rear axle in the TACX flow smart trainer
