The 73mm diameter gives it the roll speed of a larger wheel, while the weight-saving core adds the quickness and agility of a smaller wheel, as well as enhanced rebound. Breakthrough performance for longboarding, downhill, GS, and Hybrid slalom.
Urethane Formulas: Poured in Seismic's proprietary urethane compounds. Choose BlackOps formula for the ultimate balance between speed and pure grip. Choose Defcon formula for explosive speed and rebound with smooth, predictable grip-to-slip.
