The anatomically profiled design provides adaptive structural integrity to help reduce the risk of injuries to key knee ligaments and meniscus areas during aggressive riding and impacts. Key Features Nucleon Plasma knee protector with hybrid frame: a flexible composite over-injected on a high-performance polymer blend for rigidity where you need it, flexibility where you strap it. Replaceable triple segmented knee cups with a polyurethane outer shell backed by Nucleon Plasma for impact protection, flex, and scratch resistance. Self-centering knee cup plus upper and lower patella extensions for consistent coverage through flexion and extension. Four-point hinge system with anti-oxidation stainless-steel bushings for smooth articulation and stable control. Adjustable extension stops (0° to 30°) to set your desired maximum opening angle. Highly ventilated design for comfort while maximizing impact force dispersion and absorption. Bio-based, eco-friendly impact-absorbing materials. Four individual, non-slip backed straps and soft-touch thermoformed padding for a secure, comfortable fit. Easy locking central buckles with keyhole snapping system. Specifications Model: RK-1 Plasma Size: L/XL (Adult) Color/Finish: Black/Red Riding Style: Off-Road, ATV, UTV Type: Knee braces (Pair) Weight: 3.2 lbs Dimensions: 17.5" x 7" x 6.5"
Anatomically profiled for all forms of off-road riding, the RK-1 Plasma Knee Brace has been engineered to provide comfortable knee support while still being lightweight, breathable, and protective
This knee brace 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
Key Features
This brace provides optimal structural integrity and support while being ultra-lightweight and adaptive, and thus reduces the risk of sustaining injuries to the medial and lateral collateral ligament, the anterior and posterior cruciate ligament, and the lateral and medial meniscus
The replaceable triple segmented knee cups are constructed with a polyurethane outer shell backed with a Nucleon Plasma protector for the optimum blend of impact protection, flexibility, and scratch resistance
The self-centering knee cup and the strategically positioned upper and lower patella extensions ensure maximum coverage regardless of the flexion or extension angles
The stable, slim-design four-point hinge system follows the articulation of the knee while the extension stops, which are available in a range from 0° to 30°, assist in setting the brace to the desired maximum opening angle
The stainless-steel bushings in the four-point hinge system have an anti-oxidation treatment
Nucleon Plasma is a viscoelastic material engineered from bio-based polymers and formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies
Lightweight and highly ventilated, the knee protector offers strong impact force dispersion and absorption while ensuring maximum coverage in all riding positions
