With this 10 mm disc set is it possible to train very hard! The 10 mm discs can only be used in the Kynett FIT, PRO and ULTIMATE Flywheel and not in the Kynett HOME and ONE Flyhweel!
The resistance used to train is not expressed in kilograms but in a moment of inertia kgm2. Every object that rotates on a certain axis has a so-called moment of inertia. The moment of inertia can be calculated based on the mass and dimensions of the rotating disk.
