Yonex Astrox 100ZZ vs Yonex Astrox 99 Pro
Two head-heavy rackets from Yonex's range, lined up spec by spec from the makers' published figures. Rows marked in red are where they differ; the notes underneath say what each difference means on court.
Astrox 100ZZ
A very stiff, very slim-shafted attacking racket that rewards precise, fast technique with sharp smashes and accurate placement. It is one of the least forgiving rackets Yonex sells and is best left to advanced and professional players.
Full specs →Astrox 99 Pro
A heavy-hitting singles frame for strong players who generate their own racket speed and want maximum steepness on the smash. The extra-stiff shaft punishes slow swings, so it is a poor fit for developing players or fast flat doubles exchanges.

Balance, flex, weights, grips, tension and materials come from the manufacturers' published specifications; the level, play-style tags and typical prices are our own database fields and are labelled as such. We do not rate rackets we have not measured. Shaft flex and balance are the makers' own categories, so compare them within a brand with more confidence than across brands. Our head-heavy vs head-light guide and string tension guide explain what the categories mean on court.
