75.5mm tall x 62.5mm wide ALPHA Wheels
62mm running surface • Bearing seat offset 6.5% • Square outside edge, straight-cut inside edge
8.125 oz. each • Sold in sets of FOUR wheels
A highly-optimized balance of properties for modern racing
• Size and momentum to carry you past the competition in straightaways – yet agile enough for quick acceleration, fast edge-to-edge adjustments, and snappy technical pre-drifts. Welcome to a whole new realm of FAST!
• Finely-calibrated width and supremely supported edges for smooth, predictable handling through even the hardest corners.
• The very fastest urethane that the skateboard industry has ever seen, bar none.
• Named after the Greek letter “alpha” (α), used in science to represent rotational acceleration.
A giant step forward in race wheel engineering
• Stout S-shaped edge profile optimizes lip support, maximizes traction under extreme G’s, and ensures predictable slide initiation and hookup.
• Running surface features a 0.5mm concave that pre-loads edges, heightens rebound, and enhances in-slide feedback.
• Bearing seat offset 6.5% for progressive lip engagement and more consistent wear.
The Fusion™ core – integrating 15 years of advanced hub R&D
• 46mm tall x 44mm wide – the largest and most supportive hub ever seen in a wheel this size.
• Deep, wide “saddle” profile regulates lateral wheel flex, supercharges edge support, and ensures absolute mechanical lock with the urethane.
• 8 lateral support beams (hollowed-out for lightness and aesthetics) form wide ridges that create unprecedented circumferential lock and rebound.
• Robust bearing lugs.
• Formed from 85D fiber-reinforced thermoplastic – the toughest hub material in the industry.
Available in TWO proprietary formulas, with finely-tuned durometer choices.
BlackOps™: comfortable and predictable on all pavements • exceptional balance of speed and grip • extreme traction fresh • buttery and smooth sliding broken-in
• 77A Blue: Sticky and predictable “in the pavement” slide. Perfect for rough and inconsistent pavement.
Defcon™: Ultra-high-rebound, thoroughbred race ‘thane • Guinness WR speed • directional slide • long-lasting grip • slow, consistent wear
• 74A Plum (Chase Hiller 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.
DH4Life –
Super purpose-engineered wheel. Out of all of the wheels that I have ever ridden, and slid, these wheels have a true attitude of their own, in the best way possible. WhenI ride these all they want to do is go super fast. When I slide these wheels all they want to do is controlled DIRECTIONAL slides. Another insanely durable product form Seismic! Very resistant to ovaling, and flat spotting.

Mango alphas have nice skin and afterwords are good freeride wheels purples are really grippy but still have a smooth and consistent slide. The blue blackops make amazing rain wheels.
