Every ball we design at Track serves a purpose and this one is no different. The purpose behind this ball is simple, provide Track fans around the world with a classic looking ball which makes picking up spares a breeze. CORE Our new 100P features a pancake core design. Spare balls are designed to go straight, so no need for a high-tech core in this one. COVER Polyester covers provided a decent amount of hook back in the 70’s. Today they make perfect spare balls due to the low friction levels they create on modern bowling environments. FINISH The polished finished keeps this one from gripping the lane which is ideal for picking up those pesky corner pins. OVERALL It’s been said for years that straighter is greater. They don’t get much straighter than the 100P Black Sparkle
