PowerDyne’s Reactor is a ten degree kingpin angled plate that offers explosive power, and provides maximum push and acceleration at the end of every stride. The high rebound urethane cushions allow the Reactor to be responsive, agile, and stable, making this the most popular plate around. The Reactor is constructed from extruded aircraft aluminum in an ultra-lightweight design for levels of strength and weight reduction not found anywhere else in its class. To give you the best possible plate, Riedell uses 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 weight, power, and response.
