The Variant Steel Wheel takes speed and durability to a whole new level without sacrificing any grip. The Steel model was created for larger skates and players who are hard on wheels or those simply looking to maximize speed. Using Platform Core Technology allows the Variant Steel Wheel to be one of the lightest in the industry, while allowing urethane to flow through freely for durability. Revolutionary urethane provides maximum durability against cracking and splitting. The TORUS Integrated Structure Ring (ISR) prevents deflection on the center edge for maximum speed. This technology provides 30% more grip than any other wheel.
