Constructed from an innovative advanced carbon polymer compound for enhanced strength & performance, the Bionic 10 Carbon Knee Brace helps reduce the risk & severity of injury by preventing excessive hypertension of the knee in an accident. Thanks to innovative engineering the Fluid Tech is ultra-lightweight & offers a highly customizable & secure fit, while affording enhanced directional movement of the knee articulation while riding. Construction The innovative design & optimized material utilization of the exoskeleton frame constructions make the knee braces extremely lightweight while still providing higher structural strength & support. Extremely temperature resilient: knee brace performs at temperatures as low as -20°C (-4°F). Correct position of knee cup is secured accurately in place by an innovative integrative mechanical guiding system allowing multi-directional freedom of movement. Highly ventilated: channeled padding & mesh zones for optimized ventilation & airflow. Soft comfortable lateral knee padding to avoid pressure points. Additional space padding & additional condyle pads enable a high adjustability for best personal fitment. Lightweight single straps on upper frames & buckle system promotes secure fitment of the brace in all riding positions & supports rapid & effortless mounting. The newly developed C-Frame strap system holds braces perfectly in position & avoids slipping down when rider is in action & extreme movement. Two straps are linked with a semi-rigid C-shaped connector that dynamically shapes towards the dimension change of calf muscle & added optional padding provides maximum comfort. Protection Knee pivot system: new double-pivoting hinge system incorporating tool-free, fast, easily exchangeable extension stops (0, 5, 10, 15, 20, 25 & 30 degrees) to prevent hyper-extension injuries. knee protector EN1621-1:2012, level 1 Features Available in four sizes & featuring a lightweight hybrid frame construction of carbon composite cores over-injected with an advanced fibre reinforced polymer. The new patented lightweight & highly ventilated double-wall knee-cup system offers strong impact force dispersion & absorption whilst ensuring maximum coverage area in all riding positions. The ergonomically sculptured knee cup is constructed from a triple segmented polymer for flexibility & adaptivity that is backed with light padding for highest comfort. 1 knee protector
