Nittaku

Fastarc S-1

Name: Fastarc S-1
Brand: Nittaku
Price: 76000 KRW
Availability: InStock

The speed type of the Fastarc series, realising top speed through a tension speed sheet. Also suits players with less power, including women and juniors.

About this product

The lowest spin of the three Fastarc rubbers at 11.75, with speed among the highest at 15.50. Its hardness, 35 (German 45), matches C-1.

That two rubbers of identical hardness produce different figures is the interesting part. If spin is lower and speed higher at the same sponge hardness, the topsheet is what changed — this is built to return the ball with spring rather than rotation.

It is also the cheapest Fastarc at ₩76,000. For a player who wins through fast exchanges and angles rather than spin, this is the better match, and there is no reason to pay more for G-1.

For a game built on driving the ball, 11.75 is the weakest spin figure in the family.

What the numbers say

Inverted, 35° (45° German scale) sponge. Its speed of 9.4 ranks 4 of 23 rubbers, among the very highest. The other axes sit at a similar level, so the profile is well balanced. Based on the manufacturer’s published figures.

Where this rubber sits among Nittaku inverted rubbers

Speed and spin figures Nittaku publishes for 14 of its inverted rubbers. Nittaku does not state a maximum, so read this as relative position within the family. Further right is faster; higher means more spin. Other brands use different scales and are not mixed in.
