The rules of the game have changed. New from Track, the Rule uses the Morpheus 2.0 core and takes it to the next level, adding the rev-enhancing lever so the ball revs faster, responds to friction better and gives you more angle on the back end. We topped this improved core with our new Goo coverstock, which gives you more friction in oil without giving up the back end angularity offered by the core. This cutting-edge combination of Track technology makes the Rule unstoppable and lets you redefine the rules of your own game.
