Amp Up Your Ride with
the NEW 90mm MEGAWATT

90mm tall x 58mm wide

The world’s fastest urethane and most progressive hub-and wheel engineering bring unparalleled rebound and superior energy efficiency to a huge 90mm-diameter shape.
Higher top speeds, longer push distances, and extended ESK8 battery life and riding range!
Next-level weight-saving Turbine™ hub features bigger vent holes for more accessible e-board pulley adapter fitting.
Hub structure ingeniously sculpted for highly-optimized routing of wheel rebound energy.
Width, edge profiles, and bearing seat offset finely calibrated for race-style grip and more consistent wear.
Half-millimeter concave running surface preloads edges, sharpens grip, enhances rebound.
Surprisingly quick, smooth, and agile handling for its size, even through hard corners. In a class by itself!

With a remarkable set of unique and highly-advanced properties, Seismic’s DEFCON ultra-high-rebound urethane is the fastest formula in the history of skateboard racing, bar none.
Credited with virtually every significant world speed and distance record – including the official Guinness Standup mark (91.17 mph / 146.73 kph), the official Guinness Street Luge mark (101.83 mph / 163.88 kph), the official Guinness Standup Slide mark (73.34 mph / 117.35 kph), and the Long-Distance Push Mile, Marathon, and 24-Hour Ultra marks!
Defcon’s superior energy efficiency means not just higher speeds and longer push distances, but also noticeably longer battery life and rolling range on your e-board! (If not yet available, ask your favorite e-board brands to offer pulley adapters fitted to the Turbine hub.)
Available in two finely-tuned durometers, both with predictable handling and slow, consistent wear…
– 74A Mango: Fast, smooth, grippy, and lively underfoot. An optimal balance of properties for most surface conditions.
– 76A Mint: Ideal for smoother surfaces. Very fast roll with friendlier slide characteristics. Excellent durability.

The Turbine™ core – NEW!

Integrates nearly 20 years of advanced hub R&D.
53mm tall x 46mm wide – the largest and most supportive hub ever seen in a wheel this size.
Formed from 85D fiber-reinforced thermoplastic – the toughest hub material in the industry – with robust bearing lugs.
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 Defcon’s superior rolling rebound energy with perfect balance and revolutionary efficiency. Boosts both speed and e-board range to another level!
Stiff saddle walls trap and return lateral wheel flex energy to supercharge rebound out of pumps, carves, and tight corners.
