Seismic Alpha Mango 74a are a staple in the race and fast freeride world. With top racers on the team, they are seen as one of the first pick downhill wheels for all tracks and road types.
Seismic's description below:
"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
Defcon™: Ultra-high-rebound, thoroughbred race ‘thane • Guinness WR speed • directional slide • long-lasting grip • slow, consistent wear
• 76A Mango: Vice-like grip and very snappy directional slide, with plenty of slowdown
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."
