anomaly connection: pairs the barrel with a stiff, composite handle to offer feedback while maximizing comfort, bat speed and energy transfer on contact.anomaly end cap: designed to work with composite barrels, using light and durable materials to reduce swing weights, improve bat control and optimize performance.two-piece composite construction: designed for improved weight distribution that allows for great balance, bat speed and barrel control; 2 3/4" barrel: a barrel diameter measured at 2 ¾” – the maximum allowed in travel baseball – to optimize performance.dark matter composite barrel: a groundbreaking composite material and construction resulting in demarini’s largest-ever barrel profile with a lighter swing weight and insane performance.
