  • Description

    Ideal size and proportions for max mileage on LDP treks and max velocity in Top Speed pursuits.
    • Highly optimized for rolling efficiency without compromising traction, even through hard corners and strong pumps.
    • Surprisingly quick acceleration and nimble edge-to-edge response for its size. Speed and momentum to beat the pack.
    Finely-calibrated width and stout, highly-supported lip profiles.
    • Bearing seat offset 6.5% for progressive lip engagement and more consistent wear.
    • Running surface features a 0.5mm concave that pre-loads edges, sharpens grip, and enhances rebound.
    • Used to set the new World Record for Fastest Standup Slide. (Ambroise Trauet, 73.34 mph / 117.35 kph Toeside – June 23, 2022, in Sellraintal, Tirolean Alps, Austria – official Guinness certification expected in 2023.)

    Poured in DEFCON™ ultra-high-rebound urethane
    • The fastest formula in the history of skateboard racing, bar none.
    • Credited with virtually every significant world distance and speed record, including the official Guinness Standup mark. (Pete Connolly, 91.17 mph / 146.73 kph – Sept. 16, 2017, at The Top Speed Challenge in Quebec, Canada.)
    • 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 they aren’t already available, ask your favorite e-board brands to offer pulley adapters fitted to the Tailwind’s Fusion hub.)
    More miles per hour, distance per push, and blocks per watt! Predictable handling; slow, consistent wear.
    • Available in two finely-tuned durometers…
    – 76A Mango: Fast, smooth, and lively underfoot. An optimal balance of properties for most surface conditions.
    – 79A Mint: Ideal for smoother surfaces. Very fast roll with friendly slide characteristics. Excellent durability.

    The Fusion™ core
    • Integrates 15 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 85D fiber-reinforced thermoplastic – the toughest hub material in the industry – with robust bearing lugs.
    • Deep, wide “saddle” profile regulates lateral wheel flex and supercharges edge support.
    • Eight (8) lateral support beams (hollowed-out for lightness and aesthetics) combine with saddle profile to create unprecedented 3D mechanical lock with urethane.
    • Support beam contours form internal “turbine blade” structure that reflects and directs Defcon’s unparalleled energy return…
    – creates uniquely-efficient and perfectly-balanced dynamic rolling rebound
    – turbocharges roll and enhances e-board range
