The One wakeboard was designed for a looser overall feel and quick release off the wake that doesn't sacrifice stability. Smooth blend in the variable rail provides more predictable edge transfers. Every aspect of the One board's rocker was built for the least amount of resistance. This allows you to ride longer with less work and carry more overall speed into the wake. A stiff, tougher ATR (all terrain ride) core is built to take on any cable park. Thin profile reduces swing weight. Clean center bottom design. Deeper side vents for fins. One 134: 52.8" x 16.6".
