The Vortex has a replacement kit, where you basically replace the flywheel thingy at the back. The only problem is that the kit costs almost as much as the trainer itself, last I checked (in Norway).
I was on a Vortex myself, but sold it this autumn when i got serious about TR and indoor training. Upgraded to the Kickr Core. So if you’re on that path, I can’t recommend the Core enough. It’s basically a Kickr 2017 made quiet (my drivetrain makes the most noise now). The wheel-off simplicity is really nice.
