It pairs the asymmetric High Rev Offset Core with the HK22 Cohesion Hybrid coverstock, delivering big flare with a smooth, controllable read. Its lower intermediate differential gives it a continuous, even motion rather than a sharp, hard-to-read backend. The 3-D Offset Assault pairs strong flare with a controllable shape. The High Rev Offset core has a strong differential but a low intermediate differential, so it produces big flare with a smooth, predictable breakpoint, while the HK22 Cohesion Hybrid cover reads the midlane firmly. The result is a strong, even asymmetric that rewards revs with control. Understanding the Hammer High Rev Offset Core and Hammer HK22 Cohesion Hybrid Reactive Hammer built the 3-D Offset Assault for strong but controllable motion on medium to heavy oil. Specifically, the asymmetric High Rev Offset Core posts a 2.489 RG, a strong .053 differential, and a low .008 intermediate differential, numbers that produce high flare with a smooth, continuous breakpoint, while the HK22 Cohesion Hybrid cover at a 2000-grit finish reads the midlane firmly. As a result, it gives you strong flare with a controllable, even motion. The per-weight specifications are listed below. A Strong-Differential Asymmetric Core With a Smooth, Even Motion At the heart of the 3-D Offset Assault is the asymmetric High Rev Offset Core. At 15 lb it measures a 2.489 RG, a strong .053 differential, and a low .008 intermediate differential, a combination that produces high track flare with a smooth, continuous breakpoint. The strong differential gives it big flare while the low intermediate differential keeps the motion even and controllable. Because the core is asymmetric, layout still has an influence on the reaction, so your pro shop can tune it to your game. That mix of strong flare and a controllable, even shape is what makes the 3-D Offset Assault reward higher revs without an erratic backend. An HK22 Cohesion Hybrid for a Firm, Controllable Read The 3-D Offset Assault wraps that core in Hammer's HK22 Cohesion Hybrid Reactive coverstock at a 2000-grit finish. As a hybrid, the cover blends solid and pearl material, so it reads the midlane firmly like a solid while keeping enough cleanliness to drive rather than roll out, ideal for medium to heavy oil. Paired with the strong, even High Rev Offset core, the HK22 Cohesion Hybrid gives the 3-D Offset Assault a firm, controllable read with big flare. Leave it at the 2000-grit box finish for medium to heavy oil, take the surface lower for more traction, or polish it up for more length as the lanes dry. 3-D Offset Assault Specs RG and differential vary by weight.
