Nittaku describes the C-1 as an offensive rubber that offers high speed, an ideal arc, and powerful topspin. The concept behind the C-1 is "catch-first," and it features a Tension Spin topsheet combined with a Soft Strong sponge. The Fastarc C-1 was developed to merge the speed of the S-1 with the spin of the G-1, resulting in a balanced rubber that delivers excellent control.
