Purchase additional Kratos flywheels here. By default, the Kratos unit ships with Medium and XL flywheels, covering a broad range of applications and individual sizes/strength.
Smaller flywheels are quicker to spool up and use with low intensity in applications such as rehab and recovery, or for smaller, untrained individuals.
Size (Weight) Inertia (kg*m^2)
XL (11.94lbs) = 0.0617
L (8.3lbs) = 0.0297
M (5.88lbs) = 0.0149
S (4.16lbs) = 0.0074
XS (2.65lbs) = 0.0066
Can a small flywheel be used with a strong individual for speed inertia without the band creating slack or binding?
Yes, it can. It's great for power and ballistic training.
Can more than wheel be loaded at a time to further customize the load?
Yes, the Kratos will handle 4 plates and is expandable to 8.
