Alpinestars RK-1 Plasma Knee Braces Black/Red

Experience superior protection and comfort with the Alpinestars RK-1 Plasma Knee Braces Black/Red. Anatomically profiled for all forms of off-road riding, these advanced knee braces are engineered to provide exceptional knee support while remaining lightweight, breathable, and highly protective for demanding conditions.

Description

The Alpinestars RK-1 Plasma Knee Braces are meticulously designed to offer optimal structural integrity and support, significantly reducing the risk of injuries to key knee ligaments and menisci. At the core of their robust construction is the innovative hybrid frame, featuring a flexible composite over-injected on a high-performance polymer blend. This unique design ensures superb frame rigidity where needed, while maintaining essential flexibility in the strap areas for a dynamic and comfortable fit. The integrated Nucleon Plasma knee protector, a viscoelastic material crafted from bio-based polymers, offers strong impact force dispersion and absorption. This advanced protection is encased in replaceable, triple-segmented knee cups, providing an optimal blend of impact resistance, flexibility, and scratch resistance. The self-centering knee cup, along with strategically positioned upper and lower patella extensions, guarantees maximum coverage across all flexion and extension angles. A stable, slim-design four-point hinge system mirrors the natural articulation of the knee, complemented by adjustable extension stops (0° to 30°) for precise maximum opening angle customization. With anti-oxidation treated stainless-steel bushings, high tensile strength buckles, and soft-touch thermoformed padding, these braces deliver reliable, lightweight knee protection and comfort for every off-road adventure.
