It introduces the revolutionary tri-cylindrical Solarion A.I. Core and debuts Storm's Adhesion System coverstock technology, a combination engineered for the classic Storm skid-flip with added control and power.\n\nThe Equinox pairs that asymmetric Solarion A.I. Core with the A1S Pearl Reactive coverstock at a Power Edge polish. The low-RG core revs quickly with a tumbling front-lane read, while the polished pearl cover delivers effortless length and a sharp, controlled move at the breakpoint, the strong, angular motion that thrives on medium patterns.\n\nUnderstanding the Storm Solarion A.I. Core and Storm A1S Pearl Reactive\n\nStorm built the Equinox for a strong, controllable skid-flip on medium oil. Specifically, the asymmetric tri-cylindrical Solarion A.I. Core lowers RG for fast revving and a tumbling read through the fronts, while the A1S Pearl cover at a Power Edge polish conserves energy and stores it for a sharp, controlled move at the breakpoint. As a result, it delivers effortless length with a strong, angular backend, ideal for the medium patterns most bowlers see. The full per-weight specifications are listed below.\n\nA Tri-Cylindrical Asymmetric Core for a Strong, Decisive Skid-Flip\n\nAt the heart of the Equinox is the asymmetric, tri-cylindrical Solarion A.I. Core. At 15 lb it measures RG 2.48, a strong .054 differential, and a .018 intermediate differential (mass bias), numbers that produce heavy flare and a strong, decisive motion at the breakpoint. The core's three distinct cylinders each do a job: the largest lowers RG for fast revving and a tumbling front-lane read, the top cylinder enhances drilling versatility, and the lightweight base adds torque and continuation.\n\nThat design creates the classic skid-flip reaction Storm is known for, but with added control and power. The strong differential supplies the flare for medium oil, while the asymmetric shape drives hard and continuously through the pins. Because it is asymmetric, layout has a strong influence on the reaction, so your pro shop can tune the pin and mass bias to your game.\n\nA Polished Pearl With Adhesion System Tech for Effortless Length\n\nThe Equinox wraps that core in Storm's A1S Pearl Reactive coverstock, debuting Storm's Adhesion System technology, at a Power Edge polish. The pearl additive and polished surface conserve energy through the front of the lane, so the ball pushes cleanly through the heads, then makes a sharp, controlled move when it reaches the friction, effortless length with a strong, angular finish.\n\nThat skid-flip shape is exactly what medium patterns reward. The Equinox gets down the lane cleanly and stores its energy for a decisive backend, giving you angle and pin carry without burning up early. Leave it polished for the most length and angle, or take the surface down at your pro shop for an earlier, smoother read when the oil increases.\n\nEquinox Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Tournament Players: A strong, angular skid-flip built for the medium patterns most leagues and weekend events are played on\n\n✓Higher-Rev Bowlers: The low-RG Solarion core revs fast and stores energy for a sharp, hard-driving backend\n\n✓Angle Players: Effortless length and a decisive move at the breakpoint for bowlers who want to open up the lane\n\n✓Arsenal Builders: The pearl, length-and-angle side of the Solarion core, paired with the solid Equinox for more hook\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 polished: The Power Edge (Polished) finish runs clean and long out of the box. For an earlier read on heavier oil, take the surface down at your pro shop.\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 Equinox Fits in Your Storm Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Storm lineup, the Equinox is the strong, angular pearl for medium patterns. It clears the fronts cleanly and stores its energy for a sharp backend, so it shines when you want length and angle on medium oil. It pairs naturally with its solid sibling, the Equinox Solid, which reads earlier and hooks more for heavier volume, the two covering the Solarion core's full range.\n\nSurface Adjustments\n\nThe Power Edge polish is a length-and-angle setup out of the box. Take the surface down with a lower-grit pad for an earlier, smoother read on more oil, or re-polish to restore length. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nWipe the A1S Pearl cover with an approved reactive ball cleaner after every session, and deep clean it periodically. Keeping a polished pearl clean preserves the effortless length and sharp backend that define the Equinox.\n\nEarn points on every Storm purchase through the Striking Rewards loyalty program.
