It pairs the symmetric LED Resin Core with the NU Active coverstock, delivering controlled, readable motion with more flare than traditional urethane on dry to medium oil.\n\nThe NU 2.0 reads the lane gently and predictably like urethane, but it is tuned to create noticeably more flare than urethane or other NU options. That extra flare gives it a stronger midlane and a more readable shape while keeping the controlled, on-line motion competitive players rely on for short and broken-down patterns.\n\nUnderstanding the Hammer LED Resin Core and Hammer NU Active\n\nHammer built the NU 2.0 as a purpose-built urethane alternative with more flare than traditional urethane. Specifically, the symmetric LED Resin Core posts a 2.586 RG and a low .027 differential, numbers that produce controlled flare and a smooth, on-line motion, while the NU Active cover at a 2000-grit finish reads the lane gently like urethane but with more midlane flare. As a result, it delivers controlled, readable motion on dry to medium oil. The per-weight specifications are listed below.\n\nA High-RG Symmetric Core Tuned for Controlled Flare\n\nAt the heart of the NU 2.0 is the symmetric LED Resin Core. At 15 lb it measures a high 2.586 RG and a low .027 differential, numbers that produce controlled flare and a smooth, on-line motion. The high RG keeps the ball clean through the fronts, while the differential provides more flare than most urethane and NU options.\n\nThat extra flare is what sets the NU 2.0 apart from traditional urethane: a stronger, more readable midlane while keeping the controlled motion the category is known for. As a symmetric core, it reads the lane the same way shot after shot.\n\nA Not Urethane Cover That Reads Like Urethane With More Flare\n\nThe NU 2.0 wraps that core in Hammer's NU Active coverstock at a 2000-grit finish. NU stands for Not Urethane: the cover reads the lane gently and predictably, much like urethane, so the ball holds a controlled line on dry to medium oil and short patterns where a strong reactive ball would over-hook.\n\nWhat separates the NU 2.0 from traditional urethane is flare. The NU Active cover creates noticeably more flare than urethane or other NU options, for a stronger midlane and a more readable, repeatable shape. As urethane faces increasing tournament restrictions, the NU 2.0 gives competitive bowlers a purpose-built, rule-friendly alternative. Adjust the surface at your pro shop to fine-tune the control.\n\nNU 2.0 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 purpose-built urethane alternative for dry to medium oil as urethane faces restrictions\n\n✓Control Players: Urethane-like control with more flare and a stronger, more readable midlane\n\n✓Short-Pattern Bowlers: A controlled, predictable read for short patterns where a reactive ball over-hooks\n\n✓Arsenal Builders: The NU control piece that adds flare to the urethane-style part of the bag\n\nGood to Know Before You Buy\n\n·Control over raw hook: The lower differential means moderate total hook. For maximum board coverage on heavy oil, step up to stronger equipment.\n\n·Ships sanded for traction: The 2000 Grit finish is built to grip in oil. Polish it for more length when the volume drops.\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 NU 2.0 Fits in Your Hammer Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Hammer lineup, the NU 2.0 is the specialty control piece for dry to medium oil and short patterns. Where your reactive balls hook sharply, the NU Active NU 2.0 reads smoothly and holds its line, but with more flare than traditional urethane. Pair it with the Purple and Black Pearl Urethanes when you want even smoother, lower-flare control.\n\nSurface Adjustments\n\nThe 2000-grit finish gives the NU 2.0 its controlled, urethane-like read with extra flare. Take the surface lower for more traction, or smooth it up for a cleaner, longer read. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nWipe the NU Active cover with an approved ball cleaner after every session, and deep clean it periodically. Keeping the cover fresh preserves the controlled, readable motion that defines the NU 2.0.\n\nEarn points on every Hammer purchase through the Striking Rewards loyalty program.
