The Tuuk Lightspeed Edge holders have been patented and will only fit Tuuk LS Edge steel. This updated holder comes standard with all Bauer skates and has been built to be taller than the previous Lightspeed 2 holder to help provide tighten turns by allowing the player to be lower to the ice without bottoming out. The Lightspeed Edge holders are a one-piece construction and feature Tuuk?s trigger technology to hold the steel in place allowing you to replace your runners in a matter of seconds!
