The Seismic Alpha 75.5mm 78A Mint Defcon Wheels are designed for racers who need high-speed control, strong grip, and smooth slide initiation. With a 75.5mm diameter and 62.5mm width, these wheels provide excellent momentum for straightaways while maintaining precision for pre-drifts and tight turns. The 62mm running surface ensures consistent wear and maximum traction in high-speed conditions. Made with Seismic’s Defcon™ urethane, these wheels deliver Guinness World Record speed, ultra-high rebound, and slow, consistent wear. The 78A Mint durometer features stiff edges for increased grip while offering a friendly, controllable slide, making them an optimal choice for smooth roads and lighter riders. Built around Seismic’s Fusion™ core, the largest and most supportive hub ever used in a wheel of this size, these wheels provide maximum edge support, absolute mechanical lock with the urethane, and superior rebound. The bearing seat, offset by 6.5%, ensures progressive lip engagement and uniform wear, while the square outside edge and straight-cut inside edge maximize grip and control under extreme G-forces.
