Bat rolling for softball and baseball bats. Usssa, USA, BBCOR, ASA Bat rolling is a process that can add incredible pop and distance to any composite softball or baseball bat. Everyone knows that bats get hotter after about 500-800 hits. The trouble is, by the time you have put that many hits on the bat it is well on it’s way to being worn out. By rolling your bat you can enjoy the bat’s maximum potential from the very first swing without putting all the wear and tear on it. The bat is placed between two rollers and then pressure is applied so that as the bat passes through the rollers the bat’s fibers are stretched out. This causes the fibers to become more flexible which greatly improves the bat’s trampoline effect when the ball hits it resulting in increased batted ball speed and distance. It will make the sweet spot bigger and much more consistent as well. Rolling bats year round. only 24.99 End caps replaced/repaired Will travel.
