Designed from the highest quality stainless steel, the blade fits TuuK Lightspeed EDGE frames. Includes an opener to aid in removing the blade from the frame. Two per pack. Up to 7% shorter turning radius. A shorter turning radius means faster puck control. The Lightspeed EDGE frame is taller than the Lightspeed 2 frame. This allows for a lower, more aggressive angle when turning. This design allows for faster and tighter exits from turns.
