A pre-owned device designed to compress the composite material of a baseball or softball bat is often sought by players aiming to enhance bat performance. This process alters the bat’s structure, potentially increasing its trampoline effect upon contact with a ball.
Acquiring such a device secondhand often presents a more affordable entry point into bat modification. This allows players to explore the potential benefits, such as increased bat speed and distance, without the higher investment required for a new machine. The practice of bat rolling emerged as composite bats gained popularity, addressing the inherent stiffness of these materials and the break-in period they require. The availability of pre-owned machines further democratized access to this technology.
