Kynett STREXBOX disc sizes

Description STREXBOX Discs

Train with up to three STREXBOX discs on the Kynett STREXBOX and easily adjust inertia and training intensity by stacking discs!

Example: The STREXBOX Disc M provides a similar resistance level as the 15 mm Kynett disc set. This allows users to achieve a high training stimulus within a compact system!
