Available in two proprietary formulas ? BlackOps?: ultimate balance of speed and grip ? extreme traction fresh ? buttery and smooth broken-in ? comfortable and predictable Defcon?: Guinness WR speed ? directional slide ? long-lasting grip ? slow, consistent wear A giant step forward in race wheel engineering. The Alpha?s stout S-shaped edge profile optimizes lip support, maximizes traction under extreme G?s, and ensures predictable slide initiation and hookup. The running surface features a 0.5mm concave that pre-loads the edges, heightens rebound, and enhances in-slide feedback. The bearing seat is offset 6% for progressive lip engagement and more consistent wear. The Alpha? also marks the debut of Seismic?s proprietary Fusion? core ? at 46mm tall x 44mm wide, the largest and most supportive hub ever seen in a wheel this size. Features include a deep ?saddle? profile, 8 perpendicular support beams (hollowed-out for lightness and aesthetics), and robust bearing lugs. The Fusion minimizes lateral wheel flex, supercharges edge support, and assures absolute mechanical lock with the urethane. Formed from 85D fiber-reinforced thermoplastic ? the toughest hub material in the industry.
