Description (merchant text, shortened)
Skid-Flip Power for Medium Patterns
About the Equinox
With the majority of leagues and weekend tournaments played on medium oil patterns, Storm built the Storm Equinox to own exactly that range. 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.
The 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.
Understanding the Storm Solarion A.I. Core and Storm A1S Pearl Reactive
Storm 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.
A Tri-Cylindrical Asymmetric Core for a Strong, Decisive Skid-Flip
At 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.
That 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.
A Polished Pearl With Adhesion System Tech for Effortless Length
The 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.
