Alpinestars BIONIC-7 Knee Guards. Incorporating an advanced frame built with an innovative advanced fiberglass compound to improve performance, Bionic 7 Knee Brace is a versatile, fully CE certified knee brace. Designed for the stress of off-road driving, the Bionic 7 provides support and helps protect from a hyper-extended extension in the event of an accident. Lightweight, ventilated and highly customizable, this brace offers a personalized and secure fit. CONSTRUCTION • The new BIONIC-7 kneepad is available in 4 sizes. • The innovative design and optimized use of the construction material of the exoskeletal frame make the shoulder straps even lighter than its predecessor, while providing greater structural strength and support. • Crucial weight savings: the BIONIC-7 knee brace is lighter than previous versions of Fluid Knee Brace. • Extreme resistance to temperature: the BIONIC-7 knee brace operates at temperatures down to -20 ° C (-4 ° F). PROTECTION • The new double-jointed hinge system incorporating tool-free, fast and easily interchangeable extension latches (0, 5, 10, 15, 20, 25 and 30 degrees) to prevent hyperextension injuries. • The new patented lightweight and highly ventilated double-walled system with toggle provides a strong dispersion of impact and absorption force while ensuring the maximum coverage area in all driving positions. • Ergonomically sculpted knee cup consists of a triple-segment polymer for flexibility and adaptability, supported by lightweight padding for maximum comfort. • Ducted padding for optimized ventilation and airflow. • Soft and comfortable side knee padding to avoid pressure points. MAIN FEATURES • The lightweight single straps on the upper frame and the buckle system promote secure brace mounting in all riding positions and allow quick and effortless assembly. • The newly developed C-Frame belt system holds the shoulder straps perfectly in place and prevents slipping when the rider is in motion. • The 2 straps are connected with a semi-rigid C-shaped connector that dynamically shapes to change the size of the calf muscle.
