The Zombie core is machined from a solid billet of aluminum, using the same manufacturing processes as we use to make our famous Power Trac racing plates. This increases strength and allows us to machine the hub to a tighter tolerance than any other hub on the market. Creating the perfect fit between bearing and inner core. Cores are then treated with a special anodizing process to increase hub durability and urethane bonding. This technology is unique to the Zombie wheel line. Zombie Insane Urethane is specially formulated to our exact specifications that were developed from 75 years in the skate wheel business. What makes this wheel different from the rest? All wheels are poured using a precise time schedule to ensue product quality throughout the range. Typically wheels are poured over time, sometimes days. This can change the characteristic of a wheel poured one day vs. another or even morning vs. afternoon. This timing is what make the Zombie wheel the most unique wheel on the market. Tired of new wheels not performing like your last set? The Zombie wheel will never have this problem.
