Track Theorem Pearl Bowling Ball

The Track Theorem Pearl Bowling Ball is the perfect evolution of a proven winner. Building on the original Theorem’s sweeping backend and continuous motion, this Pearl version adds more length and an even sharper breakpoint, making it the go-to ball when you need added down-lane reaction on medium to heavy oil conditions.

Retaining the same MC2 Asymmetrical Core that made the original so effective, the Theorem Pearl upgrades the formula with a Prime Response Pearl Reactive coverstock infused with HK22 technology. This premium pearlized blend extends the ball's glide through the heads while producing a crisp, angular move at the breakpoint—ideal for bowlers looking for a clean, sharp, and continuous motion off the spot.

Polished to 1500 grit, the Theorem Pearl keeps its energy stored for the backend, offering a noticeable boost in hitting power and pin action. With a low RG of 2.47 and .046 differential, this high-performance pearl is tuned for precision and versatility without sacrificing control.
