Theorem Solid

Track Theorem Solid – Built to Read the Oil

The Theorem Solid is the latest evolution in Track’s high-performance lineup, designed to take the trusted motion of the Theorem Hybrid and Pearl and optimize it for medium to oily lane conditions. Featuring a solid coverstock formulation, this version maintains the clean length and sweeping backend motion the line is known for—while offering enhanced traction when the oil is heavier up front.

Why Bowlers Love It:

• Strong, Predictable Traction: Tackles fresh patterns and oil-heavy lanes with confidence.

• Signature Motion: Delivers the same dynamic, sweeping reaction of the original—now with more bite in the midlane.

• Versatile Arsenal Fit: Perfect as a first ball out of the bag, before transitioning to your shiny Theorem when the lanes start to break down.

Whether you're chasing carry in league or control in competition, the Theorem Solid brings reliable performance to every frame—when control and power matter most.
