C 57.5 J&H

Pimple In, Epsilon Sponge

Forehand X FACTOR sticky rubber does not need the booster to make it softer. Amazing click feel to boost your confidence.

We developed Jekyll & Hyde C57.5. This was made only possible by Artificial intelligence. Jekyll & Hyde C57.5 has a thicker top sheet, shorter pimples, and a more compact pimple arrangement.

The top sheet is coated with optimized stickiness and minimized gap and optimized integration between the top sheet and sponge allow for a clearer, more intuitive feel when hitting the ball.

Inside the Epsilon sponge, our new sponge engineering technology, the bubbles are smaller and more uniformly distributed. Low pimple geometry increases the energy transfer from epsilon sponge, so even when hitting far away epsilon sponge can power more directly deliver to the ball.
