Hammer Zero Mercy Tour Bowling Ball

The Hammer Zero Mercy Tour is built for bowlers who want a strong, confident read of the lane without giving up control. Designed for medium to heavy oil, this high-performance asymmetric combines a proven Tour-style core with a strong solid cover to create plenty of traction through the midlane and a powerful, dependable move downlane.

At the heart of the Zero Mercy Tour is the Obsession Tour Core, an asymmetric design built to give you the control and predictability serious bowlers look for when there's enough oil on the lane to use it. It helps the ball pick up confidently in the middle part of the lane while maintaining enough energy to continue through the pins.

Around it, Hammer uses the C² Tour Edition Solid Reactive coverstock, finished at 500/1000 Siaair. This aggressive surface helps the Zero Mercy Tour dig into heavier volumes and establish an earlier, stronger read than cleaner equipment. Instead of skating past the breakpoint, it gives you traction where you need it and follows it with a strong move off the spot.

The result is a ball that fits comfortably near the top of your arsenal. When the lanes are fresh, there's oil in the middle, and your benchmark ball isn't quite giving you enough traction, the Zero Mercy Tour gives you the extra strength to take control.
