The Ultra Mountain Twin is a lean and mean directional twin freestyle board built with speed boosting, chatter sucking premium materials. Balanced rocker in the tip and tail delivers serious float in the soft stuff while camber underfoot combined with Traction Tech give the Ultra Mountain Twin snap and hold on hard pack.
The Sintered 9900 base provides the speed boost you need to go big off any feature while the carbon fiber stringers and Ash veneer topsheet provide the stability to stomp. The Ultra Mountain Twin’s Power Core is specially profiled for unmatched torsional response and “pedal power” between the feet.
