Pure Hockey Says: The newest model from Bauer TUUK appearing on all new and recent Bauer skate models – including the Supreme TotalOne and Vapor APX. Bauer TUUK holders are preferred by a large majority of NHL players, even though many do not use skates that come with TUUKs from the factory. The LightSpeed 2 is 20 lighter than its predecessor and is built 3 mm higher to allow for tighter turns. The LS2 is made from a lightweight, abrasion and impact resistant plastic. The runner locks in using one screw in the back half and a Sharktooth in the front half to reduce hardware weight. This holder is the top choice among Pros for a reason!
