More miles per hour, distance per push, and blocks per watt!

• The worlds 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!

Poured in DEFCON the worlds fastest urethane!

• With a remarkable set of unique and highly-advanced properties, Seismics 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!
• Defcons 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 Defcons 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.
