Poured in Seismic's breakthrough freeride urethane.  Sugary, chalky, use whatever terms you like. The grip-to-slip ratio of this new 'thane is in the perfect zone for smooth, controlled slides with great hookup and grip when you need it. Superior durability compared to other freeride urethanes - due to the advanced new formula, slightly wider contact patches, and centerset hubs, which make the wheels completely rotatable. The softer yellow duro is just grippy enough for comfort through hairpin turns, while the blues are outstanding for freeride and technical sliding. All-around great wheels, poured in a fantastic new formula. (Courtesy Seismic Skate Systems)
