The frame is sold individually, left and right. The higher profile of the frame than the Lightspeed 2 model helps you turn tighter and exit corners faster. The frame features a quick-change blade system. Only EDGE blades fit the frame. The turning radius is up to 7% shorter. A shorter turning radius means faster puck control. The Lightspeed EDGE frame is higher than the Lightspeed 2 frame. This allows for a lower position of the skate relative to the ice during turns, creating a more aggressive angle. This design allows for faster and tighter exits from turns when turning.
