The CF5 offers Demarini's new TR3 composite. It is both the handle and the barrel. The triangle formation at the molecular level of the composite provides a fixed ratio of sides and angles, so it is strong, stable and predictable. It is a very lightweight yet strong composite. This along with the geo encap makes this bat evry well balanced. The dual density internal end cap is full of load balancing triangles desgined to maintain stiffness in the barrel while dampering vibration.
