    The Ebonite Challenge brings the latest High Performance Technology to the Bowling Industry.


    Core: All new AXS core design focuses on bringing the best we can design in core dynamics and shape!

    • Contour Planes – With all the research our R and D team has done on contour planes, the new AXS core has been designed to allow ball drillers more confidence in drilling, by eliminating large “void” areas in the contour profile.
    • Advanced Drilling Stability – This is something that we talked about in the Empire core shape, and the AXS core shares this unique feature. As a result of the unique shape of the AXS core, you will change the values of RG and Differential at the same rate when drilling.

    Cover: We are heading down a great new path in HP cover technology…..with the all new RCS cover system. RCS stands for “Reaction Control System”. By reformulating some of our very best High Performance veneers, we are bringing the very best in cover stock technology to market.
