Alpinestars RK-1 Plasma Knee Braces

Protect your knees with the ultimate off-road defense engineered for serious performance. The Alpinestars RK-1 Plasma Knee Braces are anatomically profiled for all forms of off-road riding, delivering exceptional support while remaining lightweight, breathable, and highly protective. Featuring an innovative hybrid frame construction that blends a flexible composite over-injected onto a high-performance polymer, this brace provides superior rigidity where it matters most while retaining crucial flexibility around the strap areas. At its core, the embedded Nucleon Plasma knee protector uses eco-friendly, bio-based polymers to offer superior impact force dispersion and absorption, dramatically reducing the risk of major ligament and meniscus injuries.

Designed to move with the natural articulation of your body, these braces feature a slim four-point hinge system equipped with adjustable extension stops ranging from 0° to 30° for a truly customized fit. The replaceable triple-segmented knee cups combine a rugged polyurethane outer shell with a Nucleon Plasma backing to provide an optimal blend of impact protection and scratch resistance, while the four-strap non-slip closure ensures the braces stay securely in place over the roughest terrain. Gear up with this premium level of impact safety and ride with complete peace of mind on your next journey with RIDE Adventures.
