The Liquid Force RDX Wakeboard with Idol 6X Bindings feature quad molded-in fins which are deep enough for extra hold when needed, but still allow for a loose, fun ride. The aggressive 3 stage rockergives you the pop you are looking for while the single to double concave center softens the landingswhen you really send it. The Idol 6X retains all the features of the 4D version, like the Reflex liner, articulated cuff, dual zonal lacing system, and Honeycomb Flexfloor™, but has the versatility ofthe 6X chassis that fits any board. The Liquid Force RDX Wakeboard with Idol 6X Bindings won't disappoint you!
