Seismic Delta 78.5mm 73.5a Wheels

Seismic Delta 78.5mm 73.5a Wheels

Next-level traction and world’s most progressive hub-and-wheel engineering!

• Revolutionary grip to hold even the most extreme lines at top velocity! Size, speed, and momentum to beat the pack on straightaways.
• Width and offset finely-calibrated for elite racing. Lips meticulously profiled for cutting-edge balance of robust support and functional flex. Subtle 0.5mm concave running surface preloads edges, strengthens rebound, and sharpens in-slide feedback.
• Superior grip and energy return when g-forces load up to peak intensity. Unparalleled braking, snappy pre-drifts, predictable slide release and hookup. Quick acceleration, nimble edge-to-edge response.
• Hub structure ingeniously sculpted for highly-optimized routing of wheel rebound energy.
• The grippiest race urethane ever seen in skateboarding, bar none.
• Named after the Greek letter “delta” (∆), used in science to represent change.

Poured in G-LOC™ – a pivotal breakthrough in race urethane formulation!

• The first significant new race compound developed since the advent of Seismic Defcon™!
• Astonishing grip and braking power with explosive roll speed.
• Directional slide.
• Slow, consistent wear and exceptional durability.
• Available in two finely-tuned durometers, both with extremely consistent, predictable handling…
• 73.5a Yellow: Fast, plush, insanely grippy, and lively underfoot. Aggressive slide characteristics with extreme braking power. Superior performance on the fastest, most technical courses.
• 75.5a Green: Ideal for smoother surfaces and lighter riders. Very fast roll with friendlier slide characteristics. Exceptional grip and excellent durability.

The FUSION™ core

• Integrates nearly 20 years of advanced hub R&D.
• 46mm tall x 44mm wide – the largest and most supportive hub ever seen in a wheel this size.
• Formed from tough, 75D fiber-reinforced Impulse Blend™ – a proprietary new hub material with next-level energy return!
• Eight (8) contoured crossbeams (hollowed-out for lightness and aesthetics) combine with deep, wide “saddle” profile to create robust edge support and ironclad 3D mechanical lock with urethane.
• Central crossbeams act as internal “turbine blades” that continuously catch and guide G-LOC’s superior rolling rebound energy with perfect balance and revolutionary efficiency.  Boosts both speed and acceleration to another level!
• Stiff saddle walls trap and return lateral wheel flex energy to supercharge rebound out of pumps, carves, and hard corners.
