Core Type
Basic shape type of the core (Symmetric, Asymmetrical, Pancake)
Asymmetrical
RG
Radius of Gyration: measurement related to weight distribution of the core. This affects how quickly a ball will get in to a roll. A ball with a higher RG will roll later. A ball with lower RG will roll sooner.
16 LB. - 2.51
15 LB. - 2.49
14 LB. - 2.48
13 LB. - 2.53
12 LB. - 2.60
Differential
Difference between the RG of the core's x-axis and y-axis. Indicates track flare potential and stability. A higher differential means more flare potential and less stabilty. A low differential ball will be more stable and have less flare potential.
16 LB. - 0.036
15 LB. - 0.038
14 LB. - 0.041
13 LB. - 0.055
12 LB. - 0.039
Intermediate Differential 
Difference between the RG of the core's x-axis and Z-axis on an asymmetrical core. Indicates the asymmetry of the core. A higher intermediate differential ball will be less stable and will transition more quickly from skid to roll than a ball with lower intermediate differential.

Kinetic Ruby Product Notes

Kinetic Ruby

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.

QR-6 Solid -  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. 

Modified Kinetic - 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!
