The Yonex Nanoflare 1000 Tour is built for competitive advanced players seeking both ultra-fast swing speed and strong repulsion. According to the official Yonex listing, the racket uses an extra stiff flex shaft.
It comes in two variants: 4U (G5,G6) and 3U (G4,G5,G6); the official stringing advice is up to 20-28 lbs for 4U and up to 21-29 lbs for 3U.
Although the manufacturer doesn't obviously label “balance” as headLight/even/headHeavy, multiple retailers list the balance as head-light, which aligns with its design focus on quick handling and fast swings rather than smash-dominant head-heavy feel.
Key design features include a longer frame by 10 mm to increase shuttle hold, a Built-in T-Joint for torso stability, and frame materials including HM Graphite, Nanocell NEO and EX-HYPER MG.
A stiff shaft offers maximum control and precision, ideal for players with fast swing speeds who can fully load the shaft.
A head-light design increases speed and maneuverability, perfect for fast defensive play and quick doubles rallies.
