Gosen Ryoga Shiden review: the cult conical-shaft speed blade, decoded
The first-generation Ryoga Shiden ('Blue-Purple Lightning') is Gosen's Zylon-and-Aermet conical-shaft 3U: a tiny sweet spot, the brand's hardest shaft, and arguably the best point-smash feel ever made.

A genuine cult classic
Gosen is best known in the West for strings, but its Ryoga racket line earned a cult following, and the first-generation Shiden is the most legendary entry. The blue-to-white finish with the flowing calligraphic name still looks high-end today, and the transparent shaft showing the carbon weave reads like a piece of craftsmanship rather than a mass-market frame. I is upfront about the usual old-Gosen weakness: the paint and stickers are fragile, picking up press marks from stringing and chipping easily. As with the other grails here, we treat this as a heritage assessment of a discontinued, now-pricey collector racket, not a current value pick.
The conical-shaft black tech
The Shiden's defining feature, and what made it ahead of its time, is a tapered shaft that narrows from about 7.5mm at the cone to 6.7mm at the T-joint. That geometry was built to resolve the tension between shaft elasticity and anti-torsion, and Gosen reinforced it with Zylon fibre, the material used in body armour, and aircraft-grade Aermet nickel-cobalt alloy steel. The result is force-transmission efficiency I rates as hard to beat even now. For a buyer, the engineering explains the character that follows: this is a frame designed to deliver everything you put in, with nothing softened or forgiven along the way.
The downsides come first, honestly
I leads with the flaws because they are unanimous among owners. The sweet spot is extraordinarily small, smaller even than a Z-Speed, so any off-centre contact produces obvious jarring and a hollow loss of power. The shaft is Gosen's hardest plus-three rating, effectively an iron bar with no spare flex. Tolerance is therefore extremely low: if your power is scattered, you will play badly with it, returns will float and smashes feel like hitting cotton. It offers nothing to paper over technique gaps. The honest buyer takeaway is that this racket demands consistent, concentrated, active power on every shot, or it will actively make you worse.
Net, drops and the hybrid-string fix
Touch was historically the Shiden's weak area: with a single thin string the wrapping feel was poor and drop placement hard to control. I's hybrid setup, a higher-friction vertical string with an explosive cross, noticeably improves this, adding bite and a better pocket so drops gain control and net spins gain precision. It still does not match a dedicated control all-rounder such as an Arcsaber 10, but it crosses from frustrating to usable. The practical lesson generalises: if you own or chase one of these extreme small-frame blades, string choice is not a detail, it is the difference between a precise tool and an unforgiving one.
Point smashes, drives and the verdict
Where the Shiden is untouchable is the point smash: hit the sweet spot and the shuttle leaves like a slingshot, instant release with zero drag, the best I has felt on any racket. Smashes are fast rather than heavy, with placement so quick the shuttle seems not to decelerate. Flat drives are its kingdom despite the 3U weight, the tiny swing weight and rigid shaft giving total mid-court control and a zero-delay, addictive feel. It is moody, state-dependent and high-ceilinged. As a purchase, accept that it is now a collector item with a steep premium: pursue it only if you have the technique to unlock it, and buy on authenticity and condition.
