We learned a lot from developing the C-Frame and X-Frame knee braces and realized that younger riders needed cage-style knee guards. The Z-Frame is not as rigid as the C-Frame, but has a good body made of glass-filled nylon for comfort.
Features:
Thin hinges provide a great motorcycle feel.
Reducing forces to limit knee injuries.
Hyper extension limits: 5°, 10°, 15° and 20° to reduce ACL injury.
The low-profile shin pads fit the shoe perfectly.
