PowerDyne™ Rival Aluminum Plates
Durable, responsive, and lightweight, the all-new Rival from PowerDyne has been engineered from start to finish by skaters whow know what a plate needs to perform. The Rival is built from extruded aircraft aluminum with an exclusive solid support beam that offers unmatched durability and rigidity for the Reactor-inspired platform. Every corner and angle of the Rival has been analyzed, stress-tested, and refined to reduce weight, increase strength, and improve feel. The attention to detail doesn’t stops there as the Rival comes with solid 7075 aluminum kingpins and high rebound urethane cushions for the instant response found in plates that are twice the price of the Rival. Lighter and more powerful than any other plate in its class, the Rival has no equal.
