Track Kinetic Cobalt 15# NIB

The Kinetic Cobalt is a mid performance hybrid reactive ball. It pairs the Shuttle core with DynamiCore outer core technology and a QR-7 Hybrid coverstock built on the HK22 base. Track finishes it at 500, 1500, 4000 Siaair, a smoother surface that keeps the angular Kinetic shape while adding mid lane traction and stronger continuation through the backend. Track rates it for medium oil, with a reaction length that is strong off the backend.

HK22 is Track's coverstock base, engineered for improved color, clarity, and translucency. DynamiCore, developed by Brunswick, is a tougher outer core material that compresses less on impact, which adds hitting power and pin carry.
