Key features, construction, and protection:
* Developed using feedback from professional MX riders, the CE-certified Level 1, Supertech RK-10 Plasma knee brace's 34-layer carbon fiber frame is engineered to provide the optimal balance of flexibility and rigidity, delivering the highest levels of rider comfort and support while reducing the risk of sustaining injuries to the medial and lateral collateral ligament, the anterior and posterior cruciate ligament, and the lateral and medial meniscus
* Frame geometry was meticulously formulated using countless 3D scans of professional athletes to ensure the optimal internal volume and precise hinge width for maximum comfort during use
* The RK-10 features a free-floating Nucleon Plasma knee protector encased in an innovative asymmetric forged carbon fiber frame construction for the highest levels of rigidity and superior weight saving properties, and offers riders the ultimate due to the knee brace's ultra-lightweight, and high levels of breathability, comfort, and protection
* Lightweight and highly ventilated, the knee protector/cup offers strong impact force dispersion and absorption while ensuring maximum coverage area in all riding positions
* Replaceable knee cups are constructed with a polyurethane outer shell backed with a Nucleon Plasma knee protector for the optimum blend of impact protection, flexibility, and scratch resistance
* Strategically positioned upper and lower patella extensions ensure maximum coverage regardless of the flexion or extension angles
* Soft tactile non-slip neoprene padding ensures the highest levels of rider comfort while keeping the knee brace securely in position and is replaceable—soft-touch neoprene condyle padding further prevents slipping of the knee brace and comes in different thicknesses for a customized fit
* Extremities of the upper and lower frames feature an innovative soft and flexible construction with a smooth transition to prevent the hard edges of the carbon fiber frame from coming into direct contact with the skin
* Extremely stable, compact low-profile four-point hinge system perfectly follows the articulation of the knee while the extension stops, which are available in a range from 0 to 30 degrees, assist in setting the brace to the desired maximum opening angle
* Replaceable hinge covers transition smoothly from the hinges to the frame, effectively eliminating any steps in the construction to avoid any possibility of material snagging
* According to European statutory law the CE mark is a conformity requirement for the marketing of this product—the following standards apply:
