Theorem Solid

The Track Theorem Solid expands on the proven success of the Theorem line by introducing a solid coverstock option designed to tackle medium to heavy oil conditions. Retaining the clean length and sweeping backend motion that made the Hybrid and Pearl versions so popular, the Solid brings added traction and earlier lane read for better performance when oil is more abundant.

Whether you're using it as your first ball out of the bag or switching to it when transition hits, the Theorem Solid is built for versatility and consistency. It’s a smart addition to your arsenal when you need a predictable shape with more bite up front—ideal for competitive bowlers who demand precision under pressure.

Why choose the Track Theorem Solid?

• Solid cover for stronger lane read and traction
• Classic Theorem motion with added control
• Ideal benchmark on medium to heavy oil
• Smooth, sweeping backend with predictable shape
• Perfect transition ball when shiny isn’t enough
