The CCM composite butt ends are designed to keep a lightweight feel while adding up to 4? of extra length to a stick. These extensions will fill almost all senior and intermediate sticks and shafts. Specificially designed to keep similar dimensions and feel to the Tacks, RBZ and Ribcor lines, these butt ends are made from full carbon composite and will not compromise the balance and responsiveness of the stick when installed. The CCM butt ends come with dried glue already on them for easy application.
