Track
The Track 715T is a ump gen4t bowling ball with the Catback core. RG 2.520 and differential 0.052 at 15 lb. For medium oil – medium-heavy oil. No longer made.
Track’s 715T is the first “T” (Track-tion) ball released in the 7 series; designed to be a stronger version of the popular 505T. The designers set out to make a more aggressive product by using an all new UMP GEN4T coverstock. This cover has a larger footprint on the lane to help carve through the head oil. The “Catback” core was unchanged and is still a 0.015 intermediate differential, which gives this ball unbelievable striking power.
