It introduces the fourth generation of the legendary I-Core, the asymmetric I-Core Gen4, paired with the QR-12 Solid (HK22C) coverstock. The result is a ball that grips the midlane, builds momentum, and finishes with strong, continuous motion on medium to heavy oil.\n\nThe Synthesis takes the proven I-Core and pushes it further. The Gen4 version adds intermediate differential for a sharper, more angular breakpoint than previous I-Cores, and the QR-12 Solid cover at a sanded finish reads the midlane with confidence. With the most flare in the line, the Synthesis is the answer when you need the most hook and the strongest backend.\n\nUnderstanding the Track I-Core Gen4 and Track QR-12 Solid (HK22C)\n\nTrack built the Synthesis for aggressive, high-flare motion on medium to heavy oil. Specifically, the asymmetric I-Core Gen4 posts a 2.48 RG, a strong .053 differential, and a high .020 intermediate differential, numbers that produce 5 to 6 inches of track flare and a sharp, angular breakpoint, while the QR-12 Solid HK22C cover at a 1500-grit Siaair finish reads the midlane and builds momentum. As a result, it gives you the strongest hook and continuation in the line. The per-weight specifications are listed below.\n\nThe Fourth Generation of Track's Legendary I-Core\n\nAt the heart of the Synthesis is the asymmetric I-Core Gen4. At 15 lb it measures a 2.48 RG, a strong .053 differential, and a high .020 intermediate differential, a combination that produces 5 to 6 inches of track flare and a sharp, angular breakpoint. The increased intermediate differential is what separates Gen4 from earlier I-Cores: it adds a more pronounced, continuous move at the spot.\n\nTrack wraps the I-Core Gen4 in DynamiCore, Brunswick's industry-leading outer-core technology, for added durability and a stronger hitting ball. Because the core is asymmetric, layout has a strong influence on the reaction, so your pro shop can tune the pin and intermediate differential to control how early and how angular the Synthesis plays.\n\nAn HK22C Solid That Reads the Midlane With Confidence\n\nThe Synthesis wraps that core in Track's QR-12 Solid (HK22C) coverstock at a 1500-grit Siaair finish. The QR-12 solid reads the midlane with confidence and builds momentum through the pattern, so the ball grips medium to heavy oil and keeps driving rather than rolling out.\n\nPaired with the high-flare I-Core Gen4, the QR-12 Solid gives the Synthesis its identity: a strong, aggressive ball that grips the midlane and finishes with continuation. The 1500-grit Siaair finish adds a touch more length than a typical sanded solid. Leave it at the box finish for medium to heavy oil, take the surface lower for even more traction, or polish it up for more length as the lanes transition.\n\nSynthesis Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Tournament Players: The strongest, highest-flaring Track ball, built for medium to heavy oil\n\n✓Higher-Rev Bowlers: The high-intermediate-differential I-Core Gen4 rewards revs with a sharp, continuous breakpoint\n\n✓Power Players: 5 to 6 inches of flare and a confident midlane read to grip oil and drive through the pins\n\n✓Arsenal Builders: The strong-oil benchmark at the top of the bag, the most overall hook in the Track line\n\nGood to Know Before You Buy\n\n·Strong, aggressive motion: This is a high-flare piece built for traction. If you want a controlled, lower-hook reaction, a lower-differential ball will suit you better.\n\n·Ships sanded for traction: The 1500 Grit finish is built to grip in oil. Polish it for more length when the volume drops.\n\n·Asymmetric layout sensitivity: Layout choices shift the reaction more than on a symmetric ball. Match the pin and mass bias to your game with your pro shop.\n\n·Colors vary: Actual colors vary somewhat from the photos shown; no two balls come out of the mold exactly alike.\n\n·Tiny pit holes are normal: A few tiny pit holes in the coverstock are a normal part of the manufacturing process.\n\n·Sold undrilled: Ships without finger holes, so it can be fitted to your hand and span.\n\nBowlersMart Tips: Where the Synthesis Fits in Your Track Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Track lineup, the Synthesis is the strongest, most aggressive piece, the ball you start with when the lane is heavy and fresh. It provides more overall hook than the angular Paragon Fire and a sharper backend than the Theorem solids. As the oil moves, step down to the Paragon line or the Theorem pieces for more length.\n\nSurface Adjustments\n\nThe 1500 Siaair Micro Pad finish gives the Synthesis its strong midlane read with a touch of length. Take the surface lower for even more traction on the heaviest oil, or polish it up for more length as the lanes transition. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nWipe the QR-12 Solid cover with an approved reactive ball cleaner after every session, and deep clean it periodically. Keeping the cover fresh preserves the strong midlane read that defines the Synthesis.\n\nEarn points on every Track purchase through the Striking Rewards loyalty program.
