Overview
Yonex USA identifies the ASTROX 77 TOUR as an unstrung badminton racquet. The reviewed product page lists 4UG5, an additional 4U (83 g avg.) notation, medium shaft flex, a 10 mm-longer length, 4U 20–28 lb stringing advice and a 22 × 21 string pattern.
Construction and context
Yonex USA lists HM GRAPHITE, LIGHT FEEL, CARBON NEO, TUNGSTEN and NANOMESH NEO in the material field, alongside named technology labels. These are manufacturer-published construction and technology descriptors for the cited model, not independent measurements or evidence of a specific playing outcome.
Who it may suit
This entry may help a shopper verify an ASTROX 77 TOUR listing against Yonex’s published configuration, tier, material labels, flex, length and stringing fields. Those catalog fields do not determine personal comfort, handling, fit or on-court results.
Specifications in context
- 4UG5; 4U (83 g avg.)
- Yonex’s page identifies the reviewed option as 4UG5 and separately gives a 4U average-weight notation; it should not be read as an exact individual-racquet measurement.
- Medium shaft flex
- This is Yonex’s published flex label for the model, useful when checking catalog information but not a promise about feel or results.
- 4U 20–28 lbs stringing advice
- This is manufacturer guidance attached to the listed 4U configuration, not a universal setup instruction for every string or player.
Tradeoffs and caveats
- Yonex lists this reviewed USA configuration as 4UG5, so a retailer listing with another weight or grip notation should be checked carefully.
- The 4U (83 g avg.) statement is an average-weight notation, not an exact finished weight for each individual racquet.
- The listed unstrung configuration means strings, tension, installation and grip changes can affect a finished setup.
