We developed Jekyll & Hyde C55.0. This is the first dual-tension rubber with X-Factor that doesn't require booster dual tension and is already built-in. This was made possible only by artificial intelligence. Jekyll & Hyde C55.0 has a thicker top sheet, shorter pimples, and a more compact pimple arrangement.

The Jekyll & Hyde C55.0's top sheet is coated with optimized stickiness and minimized gap, ensuring an enhanced feel when hitting the ball. The optimized integration between the top sheet and sponge further enhances this experience, providing a clearer, more intuitive feel.

Inside the Jekyll & Hyde C55.0, our new sponge engineering technology, Epsilon sponge, features smaller and more uniformly distributed bubbles. This, combined with the low pimple geometry, increases the energy transfer from the sponge, ensuring that even when hitting far away, the sponge can power more directly deliver to the ball.
