A perfect balance of optimal properties for modern competitive racing: size and momentum to carry you past the competition in straightaways; finely-tuned width and supremely supported edges for smooth, predictable handling through even the hardest corners combined with a very fast urethane that the skateboard industry has ever seen.
The Alpha’s stout S-shaped edge profile optimizes lip support, maximizes traction under extreme G’s, and ensures predictable slide initiation and hookup.
Seismic's Fusion™ Core – at 46 mm tall x 44 mm wide, the largest and most supportive hub ever seen in a wheel this size.
Formed from 85D fiber-reinforced thermoplastic – the toughest hub material in the industry.
