The next evolution of Tour control. The Zero Mercy Tour continues Hammer's benchmark legacy — following the Obsession Tour, Envy Tour, and Effect Tour — by bringing back the proven Obsession/Envy Tour core and pairing it with a first-of-its-kind cover innovation.

For the first time, the HK22C² additives that made the Zero Mercy line one of Hammer's biggest recent successes have been infused into a Tour cover formulation. You get the traction to handle heavier oil volumes and the smooth, predictable, continuous motion Tour ball players demand. It reads with confidence, handles volume with ease, and keeps driving through the pins.

Who It's For

• Tournament bowlers — a true tour piece with low-diff control and smooth, repeatable motion.
• Heavy-oil players — the C² Tour Edition cover holds up on volume where most benchmarks give up.
• Obsession/Envy Tour fans — the proven core is back, this time with modern cover chemistry.
