ERA wheels Elevate your inline speed skating performance with Powerslide ERA Wheels, meticulously engineered for racers seeking the perfect balance of grip, speed, and durability. Available in 100mm and 110mm diameters, and in medium (~84A) and hard (~86A) hardness options, these wheels cater to diverse racing preferences. At the heart of the ERA Wheels lies a dual-density polyurethane construction. The softer inner layer enhances grip and comfort by increasing the wheel's footprint during strides, while the harder outer layer ensures maximum roll and speed . The optimized ERA race hub is designed to provide the perfect balance between flex and rigidity, offering responsive energy transfer and stability at high velocities. Its flat surface design allows for more polyurethane, extending grip and energy return during each push. Crafted with raw urethane sourced from France, both the polyurethane and the hub's injection materials are produced in France, ensuring premium quality. The final casting and processing occur in Germany, reflecting Powerslide's commitment to European manufacturing excellence. The round profile contact surface ensures smooth transitions and consistent performance, making the ERA Wheels an ideal choice for competitive skaters aiming for podium finishes.
