Precision Engineering! 

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.

Ball of the Year Contender!!

This ball is all that and more!! Mine rolls well on house & sport conditions!! I feel like it reads just enough in the fronts with plenty of continuation downlane. The more i roll it, the better it gets. It is a MUST HAVE!!!

The Pythagorean Theorem

Theorem - House Patterns and Sport Patterns

One of my favorite bowling balls right here, Versatile is the aka name for the Theorem. You want it to be a hook monster no problem hit is with some surface lower the number the better. Want to see the Theorem be smooth throughout the lane no problem hit it with 2000/3000 or just 3000. Want to see the Theorem snap with fun watching SKID FLIP leave it box or hit it with 1000 or 2000 then polish it. Almost anything you want to see from the Theorem you are going to get. What is most impressive for me is the true roll on house and sport patterns sure you might leave a good amount of back row but aren’t you getting to the pocket? The finish through the pins is ridiculously GOOD in my opinion. This is similar to what I have said about other bowling balls if this not it the Theorem will show you but I think the Theorem is a bowling ball you can use from game one to game X without having to do a lot of guessing. The Theorem did this ok adjustment, the Theorem did that ok adjustment. Almost like having the answers to the test but you remember or memorized them from studying not cheating. The Theorem is kind of like that.

Ball of the Year?

The Track Theorem is mentioned in the discussion as Ball of the Year! Rightfully so!! This is another great hybrid asymmetrical option for sport and medium to long patterns for transition. It is very clean through the heads (front) and mid part of the lane and gives you a strong angular motion off the breakpoint. This ball is great for all bowlers!!! Go see your pro shop today and get this ball in your bag!!

Ball of the Year!

What can I say? This is the “Ball of the Year” in my opinion, coming from Track. Switch to this asymmetric ball when you need something to get through the heads clean but have some angularity on the back ends and continuity through the pins, thanks to the hybrid HK22 cover. You’ll find this ball to be super versatile on a variety of lane conditions. This is one of those balls that’s great for a beginner, recreational bowler, competitive bowler or professional. Get one now!

On Top For A Reason

Layout: 60 x 4.5 x 30

Just a flat out winner all the way around. The ball doesn’t quite on the backend and is very clean through the front part of the lanes. There’s a reason you are seeing this ball on almost every PBA telecast and big scores are being posted week in and week out in leagues. If you haven’t tried a track ball, this is the number 1 ball in this brand I would recommend.
