Track Theorem Solid Bowling Ball

An Early-Reading Asymmetric for Medium to Heavy Oil

About the Theorem Solid

The Track Theorem Solid is the earlier-reading, stronger version of the Theorem. It pairs the asymmetric MC2 Asym Core with the Super Response Solid (HK22C) coverstock at a sanded finish, so it reads the midlane early and makes a strong, controllable move through the pins on medium to heavy oil. It is the traction-first piece of the Theorem pair.

The Theorem Solid shares the proven MC2 asymmetric core with the Theorem Pearl but wraps it in a stronger, sanded HK22C solid. The Super Response Solid cover grabs the midlane earlier than the pearl, so the Theorem Solid reads sooner and rolls stronger, giving you an early, defined asymmetric shape when the lane has more oil.

Understanding the Track MC2 Asym Core and Track Super Response Solid (HK22C)

Track built the Theorem Solid for an early, strong asymmetric read on medium to heavy oil. Specifically, the asymmetric MC2 Asym Core posts a 2.47 RG, a .046 differential, and a .017 intermediate differential for a defined breakpoint, while the Super Response Solid HK22C cover at a 2000-grit Siaair finish reads the midlane early and drives through the pins. As a result, it gives you a strong, controllable asymmetric motion. The per-weight specifications are listed below.

A Defined Asymmetric Core, Shared With the Theorem Pearl

At the heart of the Theorem Solid is the same asymmetric MC2 Asym Core used in the Theorem Pearl. At 15 lb it measures a 2.47 RG, a .046 differential, and a .017 intermediate differential, a combination that produces strong flare and a defined, asymmetric breakpoint.

Track wraps the MC2 core in DynamiCore, Brunswick’s industry-leading outer-core technology, for added durability and a stronger hitting ball. Pairing this core with a sanded solid cover is what gives the Theorem Solid its early, strong read, and because it is asymmetric, your pro shop can tune the layout to your game.

A Sanded HK22C Solid for an Early, Strong Read

The Theorem Solid wraps that core in Track’s Super Response Solid (HK22C) coverstock at a 2000-grit Siaair finish. The solid cover and sanded surface read the midlane early, so the ball gets into a strong roll on medium to heavy oil and makes a controllable, continuous move rather than skidding too far down the lane.

That early, traction-first read is what separates the Theorem Solid from the Theorem Pearl: it reads sooner and rolls stronger, making it the choice when the lane has more oil. Leave it at the 2000 Siaair box finish for medium to heavy oil, take the surface lower for more traction, or polish it up for a cleaner, longer look as the lanes dry.
