In contrast to the all-around Speed, the second chapter of Madness, "Pure Madness," has been developed with aggressive specifications that run and cut. By combining an HK22-equipped solid cover with a core specialized for sharp cuts, this ball features a sharp break point unlike any solid-type ball before. Ensuring an entry angle at the back end despite being resistant to oil means an absolute advantage in score-making. The appeal of Columbia's maverick, Madness, can only be understood by those who have experienced it. ▶Coverstock: HK22-ERT Solid ▶Core: Craze ▶Color: Black/Red/Yellow ▶Hardness: 75～77 ▶Factory Finish: 2000 Micro Pad ▶RG: 2.495 ⊿RG: 0.048 ▶Mass Bias: 0.012 ▶Performance: Strong Mid-Lane and Backend ▶Best Lane Condition: Heavy Oil ▶Available Weights: 13～15
