Even More Versatility!
Track’s Theorem line continues to push the boundaries of performance with the launch of the new Theorem Solid. Building on the success of the Theorem Hybrid and Pearl, the Theorem Solid brings the same length and strong sweeping motion that made the original so popular—only now, it’s engineered to tackle medium to oily lanes with its built-in traction. This solid version fills a crucial gap in the lineup, giving you a ball that works as a reliable first ball out of the bag or a go-to option when conditions demand a bit more hook before reaching for the shiny versions. If you loved the clean, dependable reaction of the original Theorem, the Theorem Solid takes that same dynamic shape and adapts it for even more versatility when there’s more oil on the lanes.
