The RK-7 Plasma Knee Braces combine a slim ergonomic design with high off‑road performance and comfort during dynamic movement. 🏍️

Key features

• Free-floating Nucleon Plasma knee protector encased in an asymmetric, fiber-reinforced frame for enhanced rigidity and impact management.
• Replaceable polyurethane outer-shell knee cups backed by Nucleon Plasma for the optimum blend of impact protection, flexibility and scratch resistance.
• Strategically positioned, replaceable upper and lower patella extensions that maintain maximum coverage across flexion and extension angles.
• Extremely stable, slim-design four-point hinge system that follows knee articulation; extension stops are exchangeable from 0° to 30° to set the desired maximum opening angle.
• Stainless-steel bushings with anti-oxidation treatment for long-term hinge performance.
