The Seismic Megawatt 90mm 74A Mango Defcon Wheels are built for riders seeking unmatched rolling efficiency, extreme speed, and long-lasting grip. With a 90mm diameter and 58mm width, these wheels provide exceptional momentum, smooth acceleration, and extended rolling range. The 53mm running surface ensures consistent wear, precise handling, and optimized grip for both e-skate and long-distance pushing (LDP). Formulated with Seismic’s Defcon™ ultra-high-rebound urethane, these wheels offer Guinness World Record speed, directional slide control, and slow, even wear. The 74A Mango durometer delivers a plush, grippy ride with a smooth and lively feel, making them ideal for varied terrain and maximum traction in high-speed riding. Designed around the brand-new Seismic Turbine™ core, the largest and most advanced hub ever seen in a wheel this size, these wheels maximize energy return, boost acceleration, and improve edge support. The bearing seat, offset by 8.6%, promotes progressive lip engagement and uniform wear, while the radiused outside edge and beveled inside edge allow for secure grip with controlled slide initiation.
