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.

Urethane: Defcon™: Guinness WR speed, directional slide, long-lasting grip, slow, consistent wear

74A Plum (Aaron Hampshire pro signature wheel): Plush, velvety roll with extra edge hold, even on rough roads. Aggressive yet smooth slide with faster braking.

76A Mango: Vice-like grip and very snappy directional slide, with plenty of slowdown power. Ideal for aggressive racing.

78A Mint: Very stiff edges that give loads of grip with a friendly slide and crisp hookup. Ideal for smooth roads and lighter riders.

Diameter: 75.5 mm Width: 62.5 mm Contact Patch: 62.5 mm Lip Profile: Square/Sharp Core Placement: Offset 6% Durometer: 74a Plum; 76a Mango; 78a Mint
