The Signum The Signum is the most recent addition to the Series Range and was inspired by requests from several top pro players for a meaty, full profile bat. The Signum ticks all the boxes and is huge throughout with no concaving. Special emphasis has also gone into a strong shoulder and toe to help withstand the forces of the modern game. Contrary to popular believe, most pro players use a bat which weighs in between 2’10” and 2’13” which means the Signum is a perfect fit.
