The Contra Wakeboard from O'Brien features a triple concave built through the midsection that transitions into defined channels exiting at the tips, providing unparalleled thrust to the wake. The variable rail has extra volume through the center for a more forgiving transition, while the unique, centrally located molded fins provide exceptional balance and control on edge. The Contra wakeboard rides deeper, allowing the rider to generate line tension effortlessly and maximize the 3-stage pop at the wake. The Fusion core continues with O'Brien's Contra and provides just a bit of flex for added snap when slashing, boosting, and softening landings. Contra 133: 52.4"L x 16.8"W. For 90-170 lb. riders.
