Key features, construction, and protection:
* The CE-certified Level 1, RK-1 Plasma knee brace provides optimal structural integrity and support while being ultra-lightweight and adaptive, and thus reduces the rider's risk of sustaining injuries to the medial and lateral collateral ligament, the anterior and posterior cruciate ligament, and the lateral and medial meniscus
* Constructed with a polyurethane outer shell, the replaceable triple segmented knee cups are backed with a Nucleon Plasma protector for the optimum blend of impact protection, flexibility, and scratch resistance

* Features a Nucleon Plasma knee protector encased in an innovative hybrid frame construction, consisting of a flexible composite over-injected on a high-performance polymer blend to offer superb frame rigidity while still being flexible at the upper and lower strap areas
* Lightweight and highly ventilated, the knee protector offers strong impact force dispersion and absorption while ensuring maximum coverage in all riding positions
* Self-centering knee cup and the strategically positioned upper and lower patella extensions ensure maximum coverage regardless of the flexion or extension angles
* Extremely stable, slim-design 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
* Stainless-steel bushings in the four-point hinge system have an anti-oxidation treatment
* Soft-touch thermoformed padding ensures the highest levels of rider comfort while keeping the knee brace securely in position and is replaceable—the soft-touch thermoformed condyle padding comes in different thicknesses for a customized fit
