Overview

Yonex USA identifies the ASTROX 100 TOUR as an unstrung badminton racquet. The reviewed product page lists 4UG5 with an additional 4U (83 g avg.) notation, head-heavy balance, extra-stiff shaft flex, a 10 mm-longer length, 20–28 lb stringing advice and a 22 × 21 string pattern.

Construction and context

Yonex USA lists HM Graphite, NANOMESH NEO, Tungsten and Namd™ in the material field and provides named technology labels. These are manufacturer-published descriptions for the cited product, not independent measurements of handling, durability, shuttle speed or other outcomes.

Who it may suit

This entry may help a shopper verify the exact listed ASTROX 100 TOUR configuration and compare its published balance label, flex, length, average-weight notation, material labels and stringing field with other catalogued badminton rackets. It does not establish individual fit or on-court results.

Specifications in context

Extra Stiff shaft flex
This is Yonex’s published flex label, useful for catalog comparison but not a prediction of personal feel or performance.
10 mm longer
Yonex lists this length descriptor for the cited configuration; it is retained as published rather than independently measured here.
20–28 lb stringing advice
This is the manufacturer’s published tension guidance, not an assurance about a chosen string setup or its durability.

Tradeoffs and caveats

  • The reviewed Yonex USA listing is specifically 4UG5; verify regional stock and configuration details before purchase.
  • The 4U (83 g avg.) notation is an average specification and not a measured value for every individual racquet.
  • The cited product is unstrung, so the final setup depends on string selection, tension, installation and grip modifications.
