Clean, controlled, snappy downlane. The Track Kinetic Sapphire is built for controlled motion when the fronts start to go and you need something quicker and sharper. In purple, sky blue, and white, it combines the Prime Response Pearl (HK22) cover with the Shuttle core for an easy-clearing, medium-flare motion that lets you open your angles without losing control.

When the fronts hook and your benchmark quits, this is the cleaner, snappier move you want.

Who It's For

• Speed-dominant players — easier length with enough pop to carry.
• Balanced bowlers — the transition ball when your benchmark reads too quick.
• Rev-dominant players — clean through the heads with a defined, controllable move.
