EVS Sports – Web & Genesis Knee Braces, including the Web Eclipse Knee Brace in Small, Medium and XL with left and right sides sold separately, plus the Genesis Knee Brace in Youth Small/Medium and Youth Large/XL. These are hard-shell hinged braces built to limit hyperextension and control lateral movement at the knee, the joint that takes the worst of a foot-plant gone wrong or a rear wheel stepping out under power. The Web frames use a polycentric hinge and adjustable strapping so the shell stays indexed on the leg through whoops and hard cornering instead of sliding down the shin, while the Genesis youth shells give smaller riders real knee brace protection sized to their leg length rather than a cut-down adult unit. Durable hinge hardware, replaceable straps and molded cuffs mean a brace survives seasons of moto rather than one bad landing. Riders coming off a soft sleeve notice it over rutted ground. Fit is everything with braces: leg circumference, side and youth versus adult sizing all change the part number. Give us your rider's measurements and we'll confirm the correct EVS knee brace size and side before you order.
