Continue the movement with Track Kinetic Ruby!
The Kinetic Ruby uses the Kinetic asymmetric core, which features a low RG/medium differential/low MB differential. Track fans have clamored for the return of this core due to its ability to store energy and change direction on the backend.
Combined with the QR-6 Solid Coverstock with a matte 500/2000 Abralon finish, the Kinetic Ruby is ready to tackle higher oil volumes and longer oil patterns with a more continuous motion.
Here's what Track has to say about the 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.
