O'Brien teamed up with kneeboarding legend Ted Bevelacqua to create a revolutionary competition-level board that is still forgiving, and it continues to be one of the most dominant kneeboards on the water. 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. Ultra deep knee wells and dual-density EVA construction offer extreme comfort and control. Smooth, fluid, and comfortable rail-to-rail transition give a consistent arc through the turn, while bottom shape and bevels take spinning to new levels. Equally at ease riding forward or backward. Includes 2:1 ratio fully padded cinch strap for ultimate hold. 51.5"L x 22.25"W.
