Featuring the Shape-Lock HD core with low RG/high differential, prepare to test the laws of gravity. This core will help provide a heavy rolling motion that will cause the pins to fall faster than you can say "evolve".
The SPEC solid reactive coverstock finished at 2000-grit Abralon, as made famous by the Crux Prime, will grab on to the lane throughout heavier conditions and not stop until it hits the pit. Evolve your game with the Gravity Evolve.
