Full specs →Where they differ
- Both are head-heavy frames with a stiff shaft, so neither asks for a faster swing than the other and the differences below are what separate them.
- Weights offered differ: Li-Ning Tectonic 9 comes in 3U / 4U / 5U, Yonex Astrox 88D Pro (3rd gen) in 3U / 4U.
- Grip sizes differ too (G5 / G6 versus G5); if you like a thin handle, check the size before buying.
- Li-Ning Tectonic 9 is rated to 32 lbs against 28 lbs for Yonex Astrox 88D Pro (3rd gen). That only matters if you string above the mid-20s; see our string tension guide.
- Play style tags differ: Li-Ning Tectonic 9 is listed for singles play, Yonex Astrox 88D Pro (3rd gen) for doubles. The tags come from the maker's positioning and the balance and flex above, not from our own play-testing.
- The materials listed by the makers differ (frame: Graphite (Dynamic Optimum frame) versus HM graphite, CSR, tungsten, 2G-Namd Flex Force; shaft: Carbon fibre, 6.6 mm shaft versus HM graphite (ultra slim shaft)). Material names are marketing terms as much as engineering ones, so treat them as a tie-breaker rather than a reason to choose.
- Li-Ning Tectonic 9 is typically around US$40 cheaper (≈ US$250 against ≈ US$290; prices vary by region).
- Yonex Astrox 88D Pro (3rd gen) is the newer design (2024 against 2022).
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.
