Spring 2026 Racer Special! – Buy five (5) sets of either durometer and get one (1) FREE set of Fullspin^® 7-Ball Steel XT Built-In bearings!

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.

Grooved Rain Wheels

Seismic Skate — Tue, 02 Oct 2018 21:06:59 +0000

Seismic teamed up with Harfang to create a series of our top race wheels specially-grooved for better traction and speed on wet road surfaces.

We use Harfang’s “Stage 1” tread pattern for maximum water evacuation, which translates to maximum speed and grip when battling thoroughly soaked conditions.

NOTE: Use only in wet conditions. Not for use on dry roads.
