The TRUE A4.5 SBP hockey stick has a 100% 3K carbon fiber core wrapped in fiber glass and has a graduated mid-flex profile for increased performance and feel in all game situations. New for 2016 is the BRT blade technology. The seamless braided tubes located at the center and and bottom of the blade produce the longest lasting and most consistent blade we've ever made, up to 50% stronger than its predecessor the ABII technology!
