The Rush 5150 has simply been the most dominant kneeboard ever designed. The extreme rocker line and hand-shaped variable bevels provide smooth edge-to-edge transitions. The very efficient wet surface produces a HUGE amount of lift. The Rush 5150 is outstanding for larger riders due to its stiffness and large surface area. The 5150?s pad has ultra deep kneewells and dual density EVA foam construction for extreme comfort and control. Equally at ease riding forwards or back, the versatile Rush 5150 will take your riding to new levels!
