Ebonite Spartan Bowling Ball

Strong, Continuous Power for Heavy Oil

About the Spartan

The Ebonite Spartan tackles heavy oil with ease, delivering strong continuation and powerful backend motion while still providing excellent traction, a rare combination. It pairs the asymmetric Iron Fist V2 Core with the solid HK22C2 Optimize coverstock, so it reads the midlane early and drives hard through the pins when the lane has the most volume.

The Spartan draws its core from the proven Iron Fist design found in Ebonite’s popular Warrior series. That aggressive asymmetric shape stores energy for heavy oil and releases it with a strong, continuous breakpoint, while the HK22C2 solid cover digs into the midlane. The result is a powerful, controllable heavy-oil ball for bowlers who need traction and drive.

Understanding the Ebonite Iron Fist V2 Core and Ebonite HK22C2 Optimize Solid Reactive

Ebonite built the Spartan for strong, continuous power on heavy oil. Specifically, the asymmetric Iron Fist V2 Core posts a 2.473 RG, a strong .053 differential, and a .019 intermediate differential, numbers that produce high flare and a defined, continuous breakpoint, while the HK22C2 Optimize Solid cover at a 500, 1500 Siaair Micro Pad finish reads the midlane early and drives through the pins. As a result, it gives you strong traction and powerful backend motion on heavy oil. The per-weight specifications are listed below.

An Aggressive Asymmetric Core From the Proven Iron Fist Design

At the heart of the Spartan is the asymmetric Iron Fist V2 Core, drawn from the proven Iron Fist design found in Ebonite’s popular Warrior series. At 15 lb it measures a 2.473 RG, a strong .053 differential, and a .019 intermediate differential, a combination that produces high track flare and a defined, asymmetric breakpoint. The aggressive shape stores energy for heavy oil and releases it with strong continuation.

Ebonite wraps the Iron Fist V2 core in DynamiCore for added durability and a stronger hitting ball. Because the 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 Spartan reads.

An HK22C2 Solid Cover That Digs Into Oil

The Spartan wraps that core in Ebonite’s HK22C2 Optimize Solid Reactive coverstock at a 500, 1500 Siaair Micro Pad finish. The solid cover and sanded surface grab the midlane early, so the ball gets into a strong roll on heavy oil and makes a controllable, continuous move rather than skidding too far down the lane.

That early, traction-first read paired with the aggressive Iron Fist V2 core is what gives the Spartan its rare combination: strong continuation and powerful backend, but with the traction to handle real volume. Leave it at the 1500 Siaair box finish for maximum traction, or polish it up at your pro shop for a cleaner, longer read as the lanes transition.
