It pairs the legendary asymmetric Gas Mask Core with the solid Aggression coverstock, delivering big flare and a strong, continuous read on medium to heavy oil. It is a dependable heavy-oil benchmark with a hard-hitting backend.\n\nThe Black Widow 2.0 built its reputation on traction and power. The high-flaring Gas Mask core reads the midlane early and drives hard, while the Aggression Solid cover at a sanded finish digs into oil. The result is the strong, predictable, feared motion that put the Black Widow on the map.\n\nUnderstanding the Hammer Gas Mask Core and Hammer Aggression Solid Reactive\n\nHammer built the Black Widow 2.0 for strong, aggressive motion on medium to heavy oil. Specifically, the asymmetric Gas Mask Core posts a 2.500 RG, a strong .058 differential, and a .016 intermediate differential for high flare and a defined breakpoint, while the Aggression Solid cover at a 2000-grit finish reads the midlane early and drives through the pins. As a result, it gives you the Black Widow's signature strong, continuous hook. The per-weight specifications are listed below.\n\nThe Legendary Asymmetric Core Behind the Black Widow Name\n\nAt the heart of the Black Widow 2.0 is the asymmetric Gas Mask Core, the weight block that built the Black Widow legacy. At 15 lb it measures a 2.500 RG, a strong .058 differential, and a .016 intermediate differential, a combination that produces big track flare and a defined, aggressive breakpoint.\n\nBecause the Gas Mask 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 strong the Black Widow 2.0 plays. That tunable, high-flaring power is the foundation of the whole Black Widow line.\n\nA Sanded Solid Cover That Digs Into Oil\n\nThe Black Widow 2.0 wraps that core in Hammer's Aggression Solid Reactive coverstock at a 2000-grit finish. The solid cover and sanded surface read the midlane early, so the ball gets into a strong roll on medium to heavy oil and drives hard and continuously through the pins.\n\nThat early, traction-first read paired with the high-flaring Gas Mask core is what gives the Black Widow 2.0 its feared reputation. Leave it at the 2000-grit box finish for medium to heavy oil, take the surface lower for more traction on the heaviest volume, or polish it up for a cleaner, longer look as the lanes dry.\n\nBlack Widow 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 proven strong asymmetric for medium to heavy oil with hard-hitting power\n\n✓Higher-Rev Bowlers: The high-flaring Gas Mask core and Aggression solid reward revs with a strong, continuous breakpoint\n\n✓Power Players: Big flare and an early-reading solid to clear oil and drive through the pins\n\n✓Arsenal Builders: A dependable strong-oil benchmark, paired with the Black Widow 2.0 Hybrid and the pearls\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 2000 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 Black Widow 2.0 Fits in Your Hammer Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Hammer lineup, the Black Widow 2.0 is a proven strong asymmetric for medium to heavy oil. It shares the Gas Mask core with the rest of the line; step to the 2.0 Hybrid for a slightly cleaner read, or move to the Black Widow Mania and Ghost Pearl pearls for length as the lane transitions.\n\nSurface Adjustments\n\nThe 2000-grit finish gives the Black Widow 2.0 its early, aggressive read. Take the surface lower for more traction on heavier oil, or polish it up for a cleaner, longer look as the lanes dry. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nWipe the Aggression cover with an approved reactive ball cleaner after every session, and deep clean it periodically. A sanded solid like the Black Widow 2.0 relies on a fresh, clean surface to keep reading the midlane early.\n\nEarn points on every Hammer purchase through the Striking Rewards loyalty program.
