Alpinestars Bionic-10 Carbon Knee Brace.

The new BIONIC-10 CARBON knee brace, thanks to its innovative design and use of advanced materials, makes knee braces even lighter than their predecessor, while ensuring greater structural strength and improved support.

It is available in four sizes and features a carbon composite core structure over-injected with an advanced fiber-reinforced polymer.
Significant weight savings: The BIONIC-10 CARBON knee brace is lighter than previous versions of the Fluid knee brace.
Extreme temperature resistance: The BIONIC-10 CARBON knee brace operates in temperatures as low as -20°C (-4°F).
Knee Rotation System: New dual-pivot hinge system incorporating quick, easy, and tool-free interchangeable extension stops (0, 5, 10, 15, 20, 25, and 30 degrees) to prevent hyperextension injuries.
The new patented, highly ventilated double-wall system provides superior impact dispersion and absorption, while ensuring maximum coverage in all riding positions.
The ergonomic knee brace is made of three-segment polymer for flexibility and adaptability, and is supported by lightweight padding for added comfort.
The correct position of the knee brace is precisely ensured by an innovative integrated mechanical guide system that allows for multidirectional freedom of movement.
Highly ventilated: Channeled padding and mesh zones for optimized ventilation and airflow.
Soft, comfortable sides, extra padding, and cushions ensure a better fit.
The lightweight individual straps on the upper frame and the buckle system allow for a secure fit in all riding positions, with quick and effortless positioning of the knee pads.
The newly developed C-Frame strap system holds the keys perfectly in place and prevents them from slipping during extreme movements.
The two straps are connected via a semi-rigid C-shaped connector that dynamically adapts to the changing size of the calf muscles, while optional additional padding ensures maximum comfort.
