Your friend probably has these. You know that one that laps you. This is the plate of choice for top skaters everywhere, the 10 degree kingpin angle of the PowerDyne Reactor offers explosive power - providing superior push and acceleration at the end of every stride - while the high rebound urethane cushions make the Reactor responsive, agile, and stable. The Reactor is constructed from extruded aircraft grade aluminum in an ultra-lightweight design for levels of strength and weight reduction not found anywhere else in its class. Because performance cannot be compromised at all, only the finest parts are used to complete the Reactor - including aluminum trucks with steel rod reinforced pivot arms, solid aluminum black anodized kingpins, and durable Delrin pivot cups. The Reactor is the ultimate combination of lightness, power, and response.
