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 DEFCON™ ultra-high-rebound formula, in three finely-tuned durometer choicesThoroughbred 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.
