RS9 Knee Brace - Pair

Key Features

Hyperextension Lockout 30

A hinge component designed to prevent hyperextension, the most common knee injury in action sports. To accommodate a variety of knees and riding styles, you’re able to adjust the hyperextension lockout from 0º-30º.

Dual Alloy Tru-Motion 2.0 Hinge

The hinge mimics knee movement giving the rider a more natural stance. To endure significant amounts of force the hinge is attached using a 2 layer composite of carbon fiber and aluminum.

Flow Vents

Exterior venting provides additional air circulation.

Form Fit Frame

Built from a proprietary blend of Polyfusion polymer, the Form Fit Frame provides a strong base that is also flexible. The Form Fit Frame bends to the contours of the rider’s thigh, allowing for a comfortable fit.

Dual Defense Knee Cups

Two interactive knee cups that slide with your knees as they flex and extend to provide full coverage and knee protection.

Click Tech Buckle

The Click Tech Buckle utilizes a quick release buckle system allowing for an easy gear up and gear down.
