EVS Sports – Axis Sport Knee Braces, including the Axis Sport Knee Brace in Black/Black/Grey in Small through XL, left and right. Braces are sold as single-side units so you can run one or a matched pair, and sizing follows thigh and calf measurement. The Axis Sport uses a rigid outer frame with a polycentric hinge that tracks the natural path of the knee, adjustable extension and flexion stops, and a hyperextension limiter that keeps the joint from loading past its safe range on hard landings and deep ruts. The internal cuffs are padded and replaceable, and the strapping system pulls the brace tight against the leg so it does not migrate under a boot top after twenty minutes of moto. That stability is what protects the ACL and MCL during a foot-catch or a hard case, and it also cuts down on the pain that turns a long trail day into an early trailer ride. Riders coming back from knee surgery use these to get on the bike with confidence. Fit is everything with a hard brace, so tell us your leg measurements, boot brand and which knee you need, and we will confirm the correct size and side before you order.
