The proof is in the pudding with Theorem from Track!

Track's newest high performance line comes in the form of Theorem. Theorem features the Prime Response Hybrid (HK22) coverstock finished at 500/1000/1500 Siaair and polished with Factory Compound. 

Paired with the MC² Asymmetric core, Theorem will create a strong skid/flip reaction on medium to heavy lane conditions.
Here's what Track has to say about Theorem:

Introducing the revolutionary Track Bowling ball, Theorem, where groundbreaking technology meets precision engineering to redefine the game. Designed to amplify performance on the lanes, Theorem features an innovative asymmetric core design where we modified the proven MC2 Technology from the Triton Elite. Its hybrid coverstock, Prime Response Hybrid with HK22, a fusion of reactive and solid materials, strikes the perfect balance between traction and backend reaction, resulting in exceptional performance on various lane conditions. Theorem’s dynamic asymmetrical core configuration paired with Prime Response Hybrid – HK22 enhances angularity, ensuring more entry angle. Whether you are a seasoned pro, a league bowler, or you just want a new Track ball, Theorem’s innovative design will elevate your game.


The Theorem is very clean through the front of the lane and provides a strong move at the breakpoint and back end. The length from this ball allows bowlers to play in the same area once stronger balls like the Archetype start to hook early.


The glossy hybrid cover needs some friction, so heavier oil is not the best option unless more surface is used. Even our medium oil pattern gave Cranker some issues on the fresh when playing too much through the oil.

Overall Summary

The Theorem provides more length than duller balls, such as the Stealth and Archetype, with a good back end motion that is a bit smoother in shape than the Paragon Pearl.
