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.
Please allow 4 weeks for flywheels to ship.

How do you make it expandable to 8 plates?
There is an additional extender piece that will soon be able to be purchased on our site.
Where can I find an instructional manual for the Kratos? I am having difficulty installing up the wall mount setup.
If your Kratos installation instructions were not included within your packaging, please email our Customer Service Division directly at; firstname.lastname@example.org
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.
