Welcome to a whole new realm of FAST! Size and momentum to carry you past the competition in straightaways - yet agile enough for quick acceleration, fast edge-to-edge adjustments, and snappy technical pre-drifts.
Finely-calibrated widths and supremely supported edges for smooth, predictable handling through even the hardest corners.
The very fastest urethane that the skateboard industry has ever seen, bar none.
Named after the Greek letter "alpha" (a), used in science to represent rotational acceleration.
The Fusion™ core, integrating 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.
Deep, wide "saddle" profile regulates lateral wheel flex, supercharges edge support, and ensures absolute mechanical lock with the urethane.
8 lateral support beams (hollowed-out for lightness and aesthetics) form wide ridges that create unprecedented circumferential lock and rebound.
Robust bearing lugs. Formed from 85D fiber-reinforced thermoplastic - the toughest hub material in the industry.
Available in DEFCON™ high-rebound formula, Defcon™: thoroughbred race 'thane
