## Description (merchant text, shortened)
Proven Tour Performance Meets the Next Evolution of Hammer Technology

About the Zero Mercy Tour

The Hammer Zero Mercy Tour continues Hammer's legacy of benchmark performance, following in the footsteps of favorites like the Obsession Tour, Envy Tour, and Effect Tour. By popular demand, Hammer brought back the proven Obsession Tour core from the Obsession and Envy Tour series and paired it with a first-of-its-kind coverstock innovation.

For the first time, the HK22C2 additives that helped make the Zero Mercy line one of Hammer's biggest recent successes have been infused into a Tour cover formulation: the C2 Tour Edition solid. The result is the perfect blend of traction and control, strong enough to handle heavier oil volumes while maintaining the smooth, predictable motion Tour ball enthusiasts love. It reads the lane with confidence, handles volume with ease, and continues through the pins without losing energy downlane, in a deep Crimson solid at a 500, 1000 Siaair Micro Pad finish.

Understanding the Hammer Obsession Tour and Hammer C2 Tour Edition Solid Reactive

Hammer built the Zero Mercy Tour for smooth, predictable benchmark motion on medium to heavy oil. Specifically, the asymmetric Obsession Tour core carries a low RG with a moderate differential (2.469 RG, .034 differential, .013 intermediate differential at 15 lb), so it revs early and rolls smoothly rather than snapping, while the C2 Tour Edition solid cover at a 500, 1000 Siaair Micro Pad finish digs into heavier volume with the HK22C2 additives that made the Zero Mercy line a success. The 13 and 12 lb weights use a dedicated core (2.597 RG, .041 differential at 13 lb). The full per-weight numbers are listed below.

The Proven Tour Core, Back by Popular Demand

At the heart of the Zero Mercy Tour is the asymmetric Obsession Tour core, the engine from the Obsession Tour and Envy Tour series that Hammer brought back by popular demand. At 15 lb it measures a low 2.469 RG, a moderate .034 differential, and a .013 intermediate differential, the classic Tour recipe: early roll, controlled flare, and a smooth, predictable arc instead of a sharp snap.

That controlled shape is what Tour ball enthusiasts love, and it is what makes the Zero Mercy Tour a benchmark: it reads the lane with confidence and continues through the pins without losing energy downlane. The 13 and 12 lb weights carry a dedicated core (2.597 RG, .041 differential, .014 intermediate differential at 13 lb).

A First-of-Its-Kind Tour Cover Infused With HK22C2 Additives

Wrapping the Obsession Tour core is the C2 Tour Edition solid coverstock, a first-of-its-kind formulation. For the first time, Hammer infused the HK22C2 additives that helped make the Zero Mercy line one of its biggest recent successes into a Tour cover, and finished it at 500, 1000 Siaair Micro Pad for a strong, sanded box surface.
