Outer shell of the ball
Prime Hybrid
Surface texture on the ball (sanded, polished, etc)
500/2000 Abralon
Lane Condition
Length and/or amount of oil on the lane
Heavy Oil
Color of the ball
Available weights
12-16lb LBS
Weight block inside the ball
Core Type
Basic shape type of the core (Symmetric, Asymmetrical, Pancake)
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.
16lb LB. - 2.50
15lb LB. - 2.49
14lb LB. - 2.51
13lb LB. - 2.58
12lb LB. - 2.61
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.
16lb LB. - 0.047
15lb LB. - 0.054
14lb LB. - 0.054
13lb LB. - 0.049
12lb LB. - 0.046
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.

Alias Product Notes


The Alias from Track can do it all. Designed with every bowling style and every lane pattern type in mind, the Alias can be drilled for any situation. Whether you want a smooth, strong mid lane, or angular motion, the Alias can be transformed into any desired ball motion.

Alias Core

Designed with every bowling style in mind, the NEW Alias core is the most versatile core that Track has ever created. Because of the extremely tight pin distance and top weight spec we have enforced, it will allow the ball driller to achieve multiple mass bias drilling angles without the addition of a weight hole. This also will allow for an intermediate differential range of perfectly symmetric .000 Intermediate Differential to a very asymmetric, high Intermediate Differential.

Prime Hybrid Coverstock

This Prime Hybrid coverstock comes with a finish of 500/2000 sanded and provides a very fast response time to friction on heavier oil conditions. It will provide more overall hook than its QR-10 predecessor.
