This is Seismic's new race wheel the Alpha, a new shape with a new 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. 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 contact patch 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. 

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


  • Diameter: 75.5mm
  • Contact Patch: 62.5mm
