**Β Sold as set of FOUR wheels **

75.5mm tall x 62.5mm wide ALPHA Wheels
62.5mm running surface β€’ Bearing seat offset 6% β€’ Square outside edge, straight-cut inside edge

A highly-optimized balance of properties for modern racing
β€’ 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 ofΒ FAST!
β€’ Finely-calibrated width and supremely supported edges for smooth, predictable handling through even the hardest corners.
β€’ The very fastest urethane that the skateboard industry has ever seen, bar none.
β€’ Named after the Greek letter β€œalpha” (Ξ±), used in science to represent rotational acceleration.

A giant step forward in race wheel engineering
β€’ Stout S-shaped edge profile optimizes lip support, maximizes traction under extreme G’s, and ensures predictable slide initiation and hookup.
β€’ Running surface features a 0.5mm concave that pre-loads edges, heightens rebound, and enhances in-slide feedback.
β€’ Bearing seat offset 6.5% for progressive lip engagement and more consistent wear.

The Fusionβ„’ core – integrating 15 years of advanced hub R&D
β€’ 46mm tall x 44mm wide – the largest and most supportive hub ever seen in a wheel this size.
β€’ Deep, wide β€œsaddle” profile regulates lateral wheel flex, supercharges edge support, and ensures absolute mechanical lock with the urethane.
β€’ 8 lateral support beams (hollowed-out for lightness and aesthetics) form wide ridges that createΒ unprecedented circumferential lock and rebound.
β€’ Robust bearing lugs.
β€’ Formed from 85D fiber-reinforced thermoplastic – the toughest hub material in the industry.

Available in DEFCONβ„’ ultra-high-rebound formula, in three finely-tuned durometer choices
Thoroughbred race β€˜thane β€’ Guinness WR speed β€’ directional slide β€’ long-lasting grip β€’ slow, consistent wear
β€’ 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.
β€’ 76A Mango: Vice-like grip and very snappy directional slide, with plenty of slowdown power. Ideal for aggressive racing.

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