TRACK KINETIC RUBY
Track bowling's Kinetic Emerald offered heavy mid-lane roll with great backend and continuation on medium oil conditions. The new Kinetic Ruby offers that same great motion, but for heavier volumes of oil and longer oil patterns.
The QR-6 Solid coverstock is a modified version of the QR-5 solid coverstock that was previously seen on the Heat X-treme. This modification allows for a faster response in oil and gives bowlers the bite in the mid-lane they're looking for.
The Modified Kinetic core is back by popular demand. This low RG, medium differential and low MB core stores energy longer and uses it quicker than Track’s other mid performance cores. You wont find an asymmetric core for this price anywhere!
