Cubi-X-Cross is a move executed during SpikeBoarding™. The upper body performs a Nordic style, single handed spike, using a SkateBoard Spike™ pat. pend. toward the rear of a longboard while the leg on the opposite side of the body performs a traditional skateboard push. These occur simultaneously. With cadence between 1-25 both legs and arms switch their actions with one another while the SkateBoard Spike™ is tossed from one hand to the next in the back or front of the athlete. The Cubi-X-Cross was innovated by Enrique G. Cubillo on August 10th, 2010 in Central Park, New York, NY. During SpikeBoard Racing™ the Cubi-X-Cross move is a mandatory move on all race course segments with an X indicator. Cubi-X-Cross comprises one third of SpikeBoarding™ and it's principle influence is cross country skiing.
