Donacle
An easy-to-control short-pips rubber optimised for knuckle-ball variation. Handles heavy attacks comfortably with chops, suiting a defensive style.
Performance
Nittaku official (scale maximum not published)The manufacturer does not publish a maximum for these figures. This chart therefore uses the actual range of its own published values across the same family as the ends of each axis. It shows relative position within that family, not an absolute score, and because the origin is not zero the differences look larger than they are. See the manufacturer figures below for the exact numbers.
About this product
A pips-out soft (short pips with sponge) rubber. Described as easy to control with knuckle-ball-style variation, able to block even powerful attacks safely — suited to defensive styles. Hardness 32.5°.
Hardness and thickness options (OX, ultra-thin, thin, medium) match its line-mate, Super Donacle, exactly. The official copy frames Donacle around ease of control and Super Donacle around amplified variation, suggesting the pair is separated by pip design rather than the stated numbers.
What the numbers say
Short pips, 32.5° sponge. Its spin of 4.1 ranks 16 of 23 rubbers, on the low side. The other axes sit at a similar level, so the profile is well balanced. Based on the manufacturer’s published figures.
