The O’Brien Rush 5150 has simply been the most dominant kneeboard ever designed. The Rush 5150 is an outstanding choice for larger riders due to its’ larger template outline (increased surface area) and its’ stiffer flex profile. The 5150’s wet surface is very fast, efficient and produces a HUGE amount of lift. Known for its’ incredibly forgiving characteristics, the aggressive rocker line and variable bevels provide smooth predictable edge-to-edge transitions. The 5150’s pad has ultra deep kneewells and dual density EVA construction for exceptional comfort and control. Equally at ease riding forwards or backwards, the versatile 5150 will take your riding to new levels.
