Seismic Delta 78.5mm Longboard Wheels

46mm x 44mm FUSION hub • Bearing seat offset 6.5% • 67.5mm running surface • Square outside edge, straight-cut inside edge • 9.25 oz. each • Sold in sets of FOUR 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.

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.
